Advances in Liposome-Encapsulated Phthalocyanines for Photodynamic Therapy. Life (Basel) 2023; 13:life13020305. [PMID: 36836662 PMCID: PMC9965606 DOI: 10.3390/life13020305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 01/12/2023] [Accepted: 01/18/2023] [Indexed: 01/24/2023] Open
Abstract
This updated review aims to describe the current status in the development of liposome-based systems for the targeted delivery of phthalocyanines for photodynamic therapy (PDT). Although a number of other drug delivery systems (DDS) can be found in the literature and have been studied for phthalocyanines or similar photosensitizers (PSs), liposomes are by far the closest to clinical practice. PDT itself finds application not only in the selective destruction of tumour tissues or the treatment of microbial infections, but above all in aesthetic medicine. From the point of view of administration, some PSs can advantageously be delivered through the skin, but for phthalocyanines, systemic administration is more suitable. However, systemic administration places higher demands on advanced DDS, active tissue targeting and reduction of side effects. This review focuses on the already described liposomal DDS for phthalocyanines, but also describes examples of DDS used for structurally related PSs, which can be assumed to be applicable to phthalocyanines as well.

Multifunctional Photoactive Nanomaterials for Photodynamic Therapy against Tumor: Recent Advancements and Perspectives. Pharmaceutics 2022; 15:pharmaceutics15010109. [PMID: 36678738 PMCID: PMC9866498 DOI: 10.3390/pharmaceutics15010109] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/16/2022] [Accepted: 12/20/2022] [Indexed: 12/31/2022] Open
Abstract
Numerous treatments are available for cancer, including chemotherapy, immunotherapy, radiation therapy, hormone therapy, biomarker testing, surgery, photodynamic therapy, etc. Photodynamic therapy (PDT) is an effective, non-invasive, novel, and clinically approved strategy to treat cancer. In PDT, three main agents are utilized, i.e., photosensitizer (PS) drug, oxygen, and light. At first, the photosensitizer is injected into blood circulation or applied topically, where it quickly becomes absorbed or accumulated at the tumor site passively or actively. Afterward, the tumor is irradiated with light which leads to the activation of the photosensitizing molecule. PS produces the reactive oxygen species (ROS), resulting in the death of the tumor cell. However, the effectiveness of PDT for tumor destruction is mainly dependent on the cellular uptake and water solubility of photosensitizer molecules. Therefore, the delivery of photosensitizer molecules to the tumor cell is essential in PDT against cancer. The non-specific distribution of photosensitizer results in unwanted side effects and unsuccessful therapeutic outcomes. Therefore, to improve PDT clinical outcomes, the current research is mostly focused on developing actively targeted photosensitizer molecules, which provide a high cellular uptake and high absorption capacity to the tumor site by overcoming the problem associated with conventional PDT. Therefore, this review aims to provide current knowledge on various types of actively and passively targeted organic and inorganic nanocarriers for different cancers.

[PMID: 36483974 PMCID: PMC9724186 DOI: 10.5306/wjco.v13.i11.880] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 09/12/2022] [Accepted: 10/18/2022] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Photodynamic therapy (PDT) is a minimally invasive form of cancer therapy, and the development of a novel photosensitizer (PS) with optimal properties is important for enhancing PDT efficacy. Folate receptor (FR) membrane protein is frequently overexpressed in 40% of human cancer and a good candidate for tumor-specific targeting. Specific active targeting of PS to FR can be achieved by conjugation with the folate moiety. A folate-linked, near-infrared (NIR)-sensitive probe, folate-Si-rhodamine-1 (FolateSiR-1), was previously developed and is expected to be applicable to NIR-PDT.
AIM To investigate the therapeutic efficacy of NIR-PDT induced by FolateSiR-1, a FR-targeted PS, in preclinical cancer models.
METHODS FolateSiR-1 was developed by conjugating a folate moiety to the Si-rhodamine derivative through a negatively charged tripeptide linker. FR expression in the designated cell lines was examined by western blotting (WB). The selective binding of FolateSiR-1 to FR was confirmed in FR overexpressing KB cells (FR+) and tumors by fluorescence microscopy and in vivo fluorescence imaging. Low FR expressing OVCAR-3 and A4 cell lines were used as negative controls (FR-). The NIR light (635 ± 3 nm)-induced phototoxic effect of FolateSiR-1 was evaluated by cell viability imaging assays. The time-dependent distribution of FolateSiR-1 and its specific accumulation in KB tumors was determined using in vivo longitudinal fluorescence imaging. The PDT effect of FolateSiR-1 was evaluated in KB tumor-bearing mice divided into four experimental groups: (1) FolateSiR-1 (100 μmol/L) alone; (2) FolateSiR-1 (100 μmol/L) followed by NIR irradiation (50 J/cm2); (3) NIR irradiation (50 J/cm2) alone; and (4) no treatment. Tumor volume measurement and immunohistochemical (IHC) and histological examinations of the tumors were performed to analyze the effect of PDT.
RESULTS High FR expression was observed in the KB cells by WB, but not in the OVCAR-3 and A4 cells. Substantial FR-specific binding of FolateSiR-1 was observed by in vitro and in vivo fluorescence imaging. Cell viability imaging assays showed that NIR-PDT induced cell death in KB cells. In vivo longitudinal fluorescence imaging showed rapid peak accumulation of FolateSiR-1 in the KB tumors 2 h after injection. In vivo PDT conducted at this time point caused tumor growth delay. The relative tumor volumes in the PDT group were significantly reduced compared to those in the other groups [5.81 ± 1.74 (NIR-PDT) vs 12.24 ± 2.48 (Folate-SiR-1), vs 11.84 ± 3.67 (IR), vs 12.98 ± 2.78 (Untreated), at Day 16, P < 0.05]. IHC analysis revealed reduced proliferation marker Ki-67-positive cells in the PDT treated tumors, and hematoxylin-eosin staining revealed features of necrotic- and apoptotic cell death.
CONCLUSION FolateSiR-1 has potential for use in PDT, and FR-targeted NIR-PDT may open a new effective strategy for the treatment of FR-overexpressing tumors.

Abstract
Photodynamic/photothermal therapy (PDT/PTT) has become a research focus of cancer treatment due to the non-invasiveness, spatio-temporal controllability, and effectiveness of repeated treatment. Here, Au@MOF core-shell hybrids were designed and constructed by the layer-by-layer method, and the thickness of the MOF shell can be adjusted by controlling the coordination reaction between the layers. Au nanorod cores mainly produce the PTT effect due to their strong absorbance at 650 nm. The porphyrin ligand in the MOF shell can convert O2 into 1O2 under light conditions, resulting in a high PDT effect. Moreover, the metal node Fe3O(OAc)6(H2O)3+ cluster of the MOF can catalyze the decomposition of H2O2 into O2 to overcome the hypoxic environment of tumors, which further improves the effect of PDT. The combination of the porphyrin ligand in the MOF structure and Au nanorods has promoted the synergistic effects of PDT/PTT. As expected, the results confirmed that Au@MOF hybrids showed no obvious biotoxicity in both cells and animal experiments, and exhibited good biocompatibility. With the synergistic effects of PDT/PTT, cancer cells could be effectively killed and tumor growth could be inhibited. In addition, the modification of folic acid on the surface of Au@MOF can further enrich the hybrids at the tumor site and enhance the inhibitory effect on tumors. These studies have proved that PDT and PTT can be effectively combined and have greater advantages in enhancing the treatment of tumors.

Abstract
Photodynamic therapy (PDT) is a promising alternative to overcome the resistance of melanoma to conventional therapies. Currently applied photosensitizers (PS) are often based on tetrapyrrolic macrocycles like porphyrins. Unfortunately, in some cases the use of this type of derivative is limited due to their poor solubility in the biological environment. Feasible approaches to surpass this drawback are based on lipid formulations. Besides that, and inspired in the efficacy of potassium iodide (KI) for antimicrobial photodynamic therapy (aPDT), the combined effect of singlet oxygen (1 O2 ) with KI was assessed in this work, as an alternative strategy to potentiate the effect of PDT against resistant melanoma cells.

Abstract
PURPOSE In order to improve the therapeutic efficiency of the chemotherapeutic drug paclitaxel in tumors, a folate-based Paclitaxel nanoemulsion (FNEs) was developed for tumor targeted treatment. METHODS In this study, we designed a folate-targeted nanoemulsion (folate/PEG-DSPE/nanoemulsion, FNEs) based on the traditional nanoemulsion using the principle of long-circulation targeting receptor mediated. The nanoemulsion (folate/PEG-DSPE/nanoemulsion, FNEs) was fabricated using high-pressure homogenization with a microfluidizer. RESULTS The nanoemulsion (folate/PEG-DSPE/nanoemulsion, FNEs) can improve the delivery efficiency of nanocarriers at the tumor site by virtue of the high expression of folate receptors on the tumor surface. Malvern Nanoseries device and transmission electron microscopy (TEM) analyses showed that the nanoemulsions were spherical with an average diameter of 140 nm. The nanoemulsions can effectively carry paclitaxel (PTX) with an encapsulation rate of about 95%. And in vitro experiments have shown that it can efficiently increase the uptake of PTX in 4 T1 breast cancer cells and FNEs had a targeting capability hundredfold higher than that of PTX-loaded nanoemulsions (PTX-NEs) without folate. In vivo experiments have shown that the pharmacokinetic parameters of FNEs were better than those of other PTX groups and FNEs can significantly enhance circulation time in the body of the subcutaneously implanted 4 T1 breast cancer in mice, increase the accumulation of chemotherapy drugs at tumor sites and effectively inhibit tumor growth with lower system toxicity. CONCLUSIONS This study can effectively improve the therapeutic efficiency of chemotherapy drugs for tumors, and provide an useful reference for solving the problem of low efficacy of chemotherapy drugs in clinical treatment of tumors.

Abstract
Photodynamic therapy (PDT) is an emerging cancer treatment combining light, oxygen, and a photosensitizer (PS) to produce highly cytotoxic reactive oxygen species that cause cancer cell death. However, most PSs are hydrophobic molecules that have poor water solubility and cannot target tumor tissues, causing damage to normal tissues and cells during PDT. Thus, there is a substantial demand for the development of nanocarrier systems to achieve targeted delivery of PSs into tumor tissues and cells. This review summarizes the research progress in PS delivery systems for PDT treatment of tumors and focuses on the recent design and development of multifunctional nanoparticles as PS delivery carriers for enhanced PDT. These multifunctional nanoparticles possess unique properties, including tunable particle size, changeable shape, stimuli-responsive PS activation, controlled PS release, and hierarchical targeting capability. These properties can increase tumor accumulation, penetration, and cellular internalization of nanoparticles to achieve PS activation and/or release in cancer cells for enhanced PDT. Finally, recent developments in multifunctional nanoparticles for tumor-targeted PS delivery and their future prospects in PDT are discussed.

Abstract
![]()
meta-Tetra(hydroxyphenyl)chlorin
(mTHPC) is one
of the most potent second-generation photosensitizers, clinically
used for photodynamic therapy (PDT) of head and neck squamous cell
carcinomas. However, improvements are still required concerning its
present formulation (i.e., Foscan, a solution of mTHPC in ethanol/propylene
glycol (40:60 w/w)), as mTHPC has the tendency to aggregate in aqueous
media, e.g., biological fluids, and it has limited tumor specificity.
In the present study, polymeric micelles with three different diameters
(17, 24, and 45 nm) based on benzyl-poly(ε-caprolactone)-b-poly(ethylene glycol) (PCLn-PEG; n = 9, 15, or 23) were prepared with mTHPC
loadings ranging from 0.5 to 10 wt % using a film-hydration method
as advanced nanoformulations for this photosensitizer. To favor the
uptake of the micelles by cancer cells that overexpress the epidermal
growth factor receptor (EGFR), the micelles were decorated with an
EGFR-targeted nanobody (named EGa1) through maleimide-thiol chemistry.
The enhanced binding of the EGFR-targeted micelles at 4 °C to
EGFR-overexpressing A431 cells, compared to low-EGFR-expressing HeLa
cells, confirmed the specificity of the micelles. In addition, an
enhanced uptake of mTHPC-loaded micelles by A431 cells was observed
when these were decorated with the EGa1 nanobody, compared to nontargeted
micelles. Both binding and uptake of targeted micelles were blocked
by an excess of free EGa1 nanobody, demonstrating that these processes
occur through EGFR. In line with this, mTHPC loaded in EGa1-conjugated
PCL23-PEG (EGa1-P23) micelles demonstrated 4
times higher photocytotoxicity on A431 cells, compared to micelles
lacking the nanobody. Importantly, EGa1-P23 micelles also
showed selective PDT against A431 cells compared to the low-EGFR-expressing
HeLa cells. Finally, an in vivo pharmacokinetic study
shows that after intravenous injection, mTHPC incorporated in the
P23 micelles displayed prolonged blood circulation kinetics,
compared to free mTHPC, independently of the presence of EGa1. Thus,
these results make these micelles a promising nanomedicine formulation
for selective therapy.

Abstract
Osteosarcoma(OS) represents the main cancer affecting bone tissue, and one of the most frequent in children. In this review we discuss the major pathological hallmarks of this pathology, its current therapeutics, new active biomolecules, as well as the nanotechnology outbreak applied to the development of innovative strategies for selective OS targeting. Small RNA molecules play a role as key-regulator molecules capable of orchestrate different responses in what concerns cancer initiation, proliferation, migration and invasiveness. Frequently associated with lung metastasis, new strategies are urgent to upgrade the therapeutic outcomes and the life-expectancy prospects. Hence, the prominent rise of micelleplexes as multifaceted and efficient structures for nucleic acid delivery and selective drug targeting is revisited here with special emphasis on ligand-mediated active targeting. Future landmarks toward the development of novel nanostrategies for both OS diagnosis and OS therapy improvements are also discussed.

Abstract
The intestinal epithelium is the main barrier for nanocarriers to orally deliver poorly water-soluble and absorbed agents. To further improve the transmembrane transport efficiency of polymeric micelles, intestinal oligopeptide transporter PepT1-targeted polymeric micelles were fabricated by Gly-Sar-conjugated poly(ethylene glycol)-poly(d,l-lactic acid). The functionalized polymeric micelles with about 40 nm diameter, uniform spherical morphology and favorable cytocompatibility with Caco-2 cells were demonstrated to distinctly enhance the cellular uptake and transmembrane transport of the loaded agents. The results of intestinal absorption strongly evidenced the higher accumulation of the micelles inside the epithelial cells, at the apical and basolateral sides of the epithelium within the villi in mice. Furthermore, the interaction of Gly-Sar decorated polymeric micelles with PepT1 was explored to promote the internalization of the micelles through fluorescence immunoassay, and the PepT1 level on the membrane of Caco-2 cells treated with the micelles appeared to change in a distinctly time-dependent manner. Both clathrin- and caveolae-mediated pathways were involved in the transcellular transport for undecorated polymeric micelles, while the transcellular transport pathway for Gly-Sar decorated ones was changed to be mainly mediated by clathrin and lipid rafts. The colocalization of Gly-Sar decorated micelles with the organelles observed by confocal laser scanning microscopy indicated that late endosomes, lysosomes, endoplasmic reticulum and Golgi apparatus appeared to participate in the intracellular trafficking progression of the micelles. These results suggested that PepT1-targeted polymeric micelles might have a strong potential to greatly promote the oral absorption of poorly water-soluble and absorbed agents.

Abstract
Cancer has become one of the major diseases of human health around the world. Conventional antitumor drugs cannot specifically target cancers and result in serious side effects. To achieve better therapy, innovative functional drug delivery platforms that will aid specific targeting for cancer cells need to be developed. In this study, transferrin (Tf), which can target cancer cells, is covalently anchored onto the surface of MSNPs via disulfide linkage, which is used for glutathione-triggered intracellular drug release in tumor cells. The successful functionalization of redox-responsive MSNPs is confirmed by using BET/BJH, TEM, TGA, NMR, and FT-IR (BET, Brunauer-Emmett-Teller; BJH, Barrett-Joyner-Halenda). In addition, polyethylene glycol (PEG) is further grafted onto the surface of MSNPs to improve the biocompatibility and stability under physiological conditions for longer blood circulation. Our in vitro studies demonstrate that DOX-loaded MSNP-SS-Tf@PEG can selectively be internalized into cancer cells via Tf/Tf receptor interactions, and then, DOX is released in HT-29 and MCF-7 cells triggered by high GSH concentration in tumor cells. Remarkably, in vivo studies demonstrate that DOX-loaded MSNP-SS-Tf@PEG can significantly inhibit tumor growth with minimized side effects through cell apoptosis determined by TUNEL assay, whereas MSNP-SS-Tf@PEG revealed no significant inhibition. In conclusion, DOX-MSNP-SS-Tf@PEG with active targeting moieties and a redox-responsive strategy has been demonstrated as a great effective drug carrier for tumor therapy in vitro and in vivo.

Abstract
Combinatory modulation of the physical and biochemical characteristics of nanocarrier delivery systems is an emergent topic in the field of nanomedicine. Here, we studied the combined effects of incorporation of active targeting moieties into nanocarriers and their morphology affecting the enhanced permeation and retention effect for nanomedicine cancer therapy. Self-assembled lipid discoidal and vesicular nanoparticles with low-polydispersity sub-50 nm size range and identical chemical compositions were synthesized, characterized, and correlated with in vitro cancer cellular internalization, in vivo tumor accumulation and cancer treatments. The fact that folate-associated bicelle yields the best outcome is indicative of the preference for discoidal carriers over spherical carriers and the improved targeting efficacy due to the targeting ligand/receptor binding. The approach is successfully adopted to design the nanocarriers for photodynamic therapy, which yields a consistent trend in in vitro and in vivo efficacy: folate nanodiscs > folate vesicles > nonfolate nanodiscs > nonfolate vesicles. Folate discs not only have shown a higher tumor uptake and photothermal therapeutic efficiency, but also minimize skin photosensitivity side effects. The advantages of nanodiscoidal bicelles as nanocarriers, including well-defined size, robust formation, easy encapsulation of hydrophobic molecules (therapeutics and/or diagnostics), easy incorporation of targeting molecules, and low toxicity, enable the scalable manufacturing of a generalized in vivo multimodal delivery platform.

Abstract
Herein, we synthesised four aza-BODIPY dyes (1-4) with the singlet oxygen generation quantum yield values of ca. 65-85%. Furthermore, we formulated a nanomedicine by encapsulating these dyes into an amphiphilic micelle, DSPE. The spherical nanomicelles formed were characterized using photophysical and morphological analyses, and their in vitro and in vivo photodynamic efficacies were investigated. One of the conjugates, DSPE-1, showed the lowest IC50 value of 2 μM against a human breast cancer cell line (MDA MB 231). The mechanism of photodynamic activity has been evaluated by employing different biophysical and morphological assays, which confirmed apoptotic cell death (ca. 80-90%) predominantly through the involvement of reactive oxygen species. Interestingly, we observed that 2 mg kg-1DSPE-1 induced enhanced apoptosis and efficient inhibition of the growth of breast tumor xenografts in NOD/SCID mice models. Herein, we demonstrated the application of aza-BODIPY nanomicelles in photodynamic therapy for the first time, and our results revealed that the DSPE-BODIPY nanomicelles enhanced the cellular uptake as well as the photodynamic activity, thereby demonstrating the use of these nanomicelles as efficient sensitizers in biological applications.

Abstract
The cancer incidence world-wide has caused an increase in the demand for effective forms of treatment. One unconventional form of treatment for cancer is photodynamic therapy (PDT). PDT has 3 fundamental factors, namely a photosensitiser (PS) drug, light and oxygen. When a PS drug is administered to a patient, it can either passively or actively accumulate within a tumour site and once exposed to a specific wavelength of light, it is excited to produce reactive oxygen species (ROS), resulting in tumour destruction. However, the efficacy of ROS generation for tumour damage is highly dependent on the uptake of the PS in tumour cells. Thus, PS selective/targeted uptake and delivery in tumour cells is a crucial factor in PDT cancer drug absorption studies. Generally, within non-targeted drug delivery mechanisms, only minor amounts of PS are able to passively accumulate in tumour sites (due to the enhanced permeability and retention (EPR) effect) and the remainder distributes into healthy tissues, causing unwanted side effects and poor treatment prognosis. Thus, to improve the efficacy of PDT cancer treatment, research is currently focused on the development of specific receptor-based PS-nanocarrier platform drugs, which promote the active uptake and absorption of PS drugs in tumour sites only, avoiding unwanted side effects, as well as treatment enhancement. Therefore, the aim of this review paper is to focus on current actively targeted or passively delivered PS nanoparticle drug delivery systems, that have been previously investigated for the PDT treatment of cancer and so to deduce their overall efficacy and recent advancements.

Abstract
Nanocarrier-based delivery systems are promising strategies for enhanced therapeutic efficacy and safety of toxic drugs. Photodynamic therapy (PDT)—a light-triggered chemical reaction that generates localized tissue damage for disease treatments—usually has side effects, and thus patients receiving photosensitizers should be kept away from direct light to avoid skin phototoxicity. In this study, a clinically therapeutic antibody cetuximab (C225) was conjugated to the surface of methoxy poly(ethylene glycol)-b-poly(lactide) (mPEG-b-PLA) micelles via thiol-maleimide coupling to allow tumor-targetable chlorin e6 (Ce6) delivery. Our results demonstrate that more C225-conjugated Ce6-loaded polymeric micelles (C225-Ce6/PM) were selectively taken up than Ce6/PM or IgG conjugated Ce6/PM by epidermal growth factor receptor (EGFR)-overexpressing A431 cells observed by confocal laser scanning microscopy (CLSM), thereby decreasing the IC50 value of Ce6-mediated PDT from 0.42 to 0.173 μM. No significant differences were observed in cellular uptake study or IC50 value between C225-Ce6/PM and Ce6/PM groups in lower EGFR expression HT-29 cells. For antitumor study, the tumor volumes in the C225-Ce6/PM-PDT group (percentage of tumor growth inhibition, TGI% = 84.8) were significantly smaller than those in the Ce6-PDT (TGI% = 38.4) and Ce6/PM-PDT groups (TGI% = 53.3) (p < 0.05) at day 21 through reduced cell proliferation in A431 xenografted mice. These results indicated that active EGFR targeting of photosensitizer-loaded micelles provides a possible way to resolve the dose-limiting toxicity of conventional photosensitizers and represents a potential delivery system for PDT in a clinical setting.

Abstract
Hydrophobic drug candidates require innovative formulation agents. We designed and synthesized lipid-DNA polymers containing varying numbers of hydrophobic alkyl chains. The hydrophobicity of these amphiphiles is easily tunable by introducing a defined number of alkyl chain-modified nucleotides during standard solid-phase synthesis of DNA using an automated DNA synthesizer. We observed that the resulting self-assembled micelles solubilize the poorly water-soluble drug, meta-tetra-hydroxyphenyl-chlorin (mTHPC) used in photodynamic therapy (PDT) with high loading concentrations and loading capacities. A cell viability study showed that mTHPC-loaded micelles exhibit good biocompatibility without irradiation, and high PDT efficacy upon irradiation. Lipid-DNAs provide a novel class of drug-delivery vehicle, and hybridization of DNA offers a potentially facile route for further functionalization of the drug-delivery system with, for instance, targeting or imaging moieties.

Abstract
Surgery, chemotherapy, radiotherapy, and hormone therapy are the main common anti-tumor therapeutic approaches. However, the non-specific targeting of cancer cells has made these approaches non-effective in the significant number of patients. Non-specific targeting of malignant cells also makes indispensable the application of the higher doses of drugs to reach the tumor region. Therefore, there are two main barriers in the way to reach the tumor area with maximum efficacy. The first, inhibition of drug delivery to healthy non-cancer cells and the second, the direct conduction of drugs into tumor site. Nanoparticles (NPs) are the new identified tools by which we can deliver drugs into tumor cells with minimum drug leakage into normal cells. Conjugation of NPs with ligands of cancer specific tumor biomarkers is a potent therapeutic approach to treat cancer diseases with the high efficacy. It has been shown that conjugation of nanocarriers with molecules such as antibodies and their variable fragments, peptides, nucleic aptamers, vitamins, and carbohydrates can lead to effective targeted drug delivery to cancer cells and thereby cancer attenuation. In this review, we will discuss on the efficacy of the different targeting approaches used for targeted drug delivery to malignant cells by NPs.

Abstract
Photodynamic therapy (PDT) is a clinically approved cancer therapy, based on a photochemical reaction between a light activatable molecule or photosensitizer, light, and molecular oxygen. When these three harmless components are present together, reactive oxygen species are formed. These can directly damage cells and/or vasculature, and induce inflammatory and immune responses. PDT is a two-stage procedure, which starts with photosensitizer administration followed by a locally directed light exposure, with the aim of confined tumor destruction. Since its regulatory approval, over 30 years ago, PDT has been the subject of numerous studies and has proven to be an effective form of cancer therapy. This review provides an overview of the clinical trials conducted over the last 10 years, illustrating how PDT is applied in the clinic today. Furthermore, examples from ongoing clinical trials and the most recent preclinical studies are presented, to show the directions, in which PDT is headed, in the near and distant future. Despite the clinical success reported, PDT is still currently underutilized in the clinic. We also discuss the factors that hamper the exploration of this effective therapy and what should be changed to render it a more effective and more widely available option for patients.

Abstract
The objective of this study was to develop an active-targeted, pH-responsive albumin-photosensitizer-incorporated graphene oxide nanocomplex as an image-guided theranostic agent for dual therapies. Herein, bovine serum albumin (BSA)-cis-aconityl pheophorbide-a (c-PheoA) conjugate was complexed with graphene oxide (GO) at ratios of 1:1, 1:0.5, and 1:0.1 with the mean hydrodynamic diameter of the resulting complex being 100-200nm. Further, with the 1:0.5 ratio, we developed a folate-BSA-c-PheoA conjugate:GO complex incorporated free PheoA (PheoA+GO:FA-BSA-c-PheoA NC) with a mean hydrodynamic diameter of 182.0±33.2nm. The release study showed that the photosensitizer from the nanocomplex was released rapidly at pH5.5 compared to that at pH7.4 when incubated for 24h. Cellular uptake results showed that the PheoA+GO:FA-BSA-c-PheoA NCs was readily taken up by B16F10 and MCF7 cancer cells. In vitro phototoxicity results showed that PheoA+GO:FA-BSA-c-PheoA NC has a higher efficacy against cancer cells than free PheoA, thereby demonstrating the synergistic effect of PS and GO in response to a single laser of 670nm. In vivo and ex vivo bioimaging results showed that fluorescence signals of higher intensity were observed in the tumor area of mice treated with PheoA+GO:FA-BSA-c-PheoA NC than those in the tumor of mice treated with free PheoA, thereby suggesting that the targeted nanocomplex selectively accumulated in the tumor area compared to free PheoA. Through antitumor study, PheoA+GO:FA-BSA-c-PheoA NC showed a synergistic effect in tumor-bearing mice by a single 671nm laser treatment. These results demonstrate that our prepared PheoA+GO:FA-BSA-c-PheoA NC can be used as a theranostic agent in phototherapies and for the photodiagnosis of cancer.

Abstract
Specific targeting towards tumors and the on-site activation of photosensitizers to diagnose tumors and reduce side effects for patients are currently the main challenges for photodynamic therapy (PDT) in the clinic. Herein, uniform diiodostyryl bodipy conjugated hyaluronic acid nanoparticles (DBHA-NPs) were successfully synthesized. The evaluation of their PDT effect at both a cellular level and in animal models of tumor-bearing mice shows that the DBHA-NPs present a remarkable suppression of tumorous growth due to their specific targeting and enhanced permeability and retention (EPR) effect. More importantly, the enzyme-activated "self-assembly and disaggregation" behavior in tumors can lead to the on-site activation of DBHA-NPs, which can diagnose the tumor exactly and reduce the side effects for patients significantly. These findings confirm that DBHA-NPs have significant potential for photodynamically activated cancer theranostics in a clinical setting.

Abstract
Photodynamic therapy (PDT) is a minimally-invasive procedure that has been clinically approved for treating certain types of cancers. This procedure takes advantage of the cytotoxic activity of singlet oxygen (¹O₂) and other reactive oxygen species (ROS) produced by visible and NIR light irradiation of dye sensitizers following their accumulation in malignant cells. The main two concerns associated with certain clinically-used PDT sensitizers that have been influencing research in this arena are low selectivity toward malignant cells and low levels of ¹O₂ production in aqueous media. Solving the selectivity issue would compensate for photosensitizer concerns such as dark toxicity and aggregation in aqueous media. One main approach to enhancing dye selectivity involves taking advantage of key methods used in pharmaceutical drug delivery. This approach lies at the heart of the recent developments in PDT research and is a point of emphasis in the present review. Of particular interest has been the development of polymeric micelles as nanoparticles for delivering hydrophobic (lipophilic) and amphiphilic photosensitizers to the target cells. This review also covers methods employed to increase ¹O₂ production efficiency, including the design of two-photon absorbing sensitizers and triplet forming cyclometalated Ir(III) complexes.

Abstract
The selective and efficient drug delivery to tumor cells can remarkably improve different cancer therapeutic approaches. There are several nanoparticles (NPs) which can act as a potent drug carrier for cancer therapy. However, the specific drug delivery to cancer cells is an important issue which should be considered before designing new NPs for in vivo application. It has been shown that cancer cells over-express folate receptor (FR) in order to improve their growth. As normal cells express a significantly lower levels of FR compared to tumor cells, it seems that folate molecules can be used as potent targeting moieties in different nanocarrier-based therapeutic approaches. Moreover, there is evidence which implies folate-conjugated NPs can selectively deliver anti-tumor drugs into cancer cells both in vitro and in vivo. In this review, we will discuss about the efficiency of different folate-conjugated NPs in cancer therapy.

Abstract
Photodynamic therapy (PDT) is a promising treatment modality for cancer with possible advantages over current treatment alternatives. It involves combination of light and a photosensitizer (PS), which is activated by absorption of specific wavelength light and creates local tissue damage through generation of reactive oxygen species (ROS) that induce a cascade of cellular and molecular events. However, as of today, PDT is still in need of improvement and nanotechnology may play a role. PDT frequently employs PS with molecular structures that are highly hydrophobic, water insoluble and prone to aggregation. Aggregation of PS leads to reduced ROS generation and thus lowers the PDT activity. Some PS such as 5-aminolevulinic acid (ALA) cannot penetrate through the stratum corneum of the skin and systemic administration is not an option due to frequently encountered side effects. Therefore PS are often encapsulated or conjugated in/on nano-drug delivery vehicles to allow them to be better taken up by cells and to more selectively deliver them to tumors or other target tissues. Several nano-drug delivery vehicles including liposomes, fullerosomes and nanocells have been tested and reviewed. Here we cover non-liposomal self-assembled nanoparticles consisting of polymeric micelles including block co-polymers, polymeric micelles, dendrimers and porphysomes.

Abstract
The antitumor effect of photodynamic therapy (PDT) mediated by a novel photosensitizer I (Ps I; {γ-[N-poly(ethyleneglycol)]folic acid}-5,10,15-tris(3-hydroxyphenyl)-20-(4-carboxyphenyl)chlorin), in which chlorin was used as a photoactive unit, folic acid as a tumor‑targeting warhead, and polyethylene glycol as a linker, on cervical carcinoma was studied in vitro and in vivo. Ps I exhibited a considerably higher cellular uptake by HeLa cells than folic acid-free analogue Ps A (tert-butyl N-poly(ethyleneglycol)ethylcarbamate-5,10,15-tris(3-hydroxyphenyl)-20-(4-carboxyphenyl)chlorin), and the cellular uptake by HeLa cells of Ps I could be competitively inhibited by excess folic acid. Moreover, at different time points after the intravenous (i.v.) injection of Ps I and A, Ps I produced a >2-fold higher tumor to normal tissue ratio in tumor-bearing nude mice as compared to Ps A. MTT assay indicated that the HeLa cell proliferation inhibition ratio was increased 34% after Ps I-PDT compared with Ps A-PDT with a photosensitizer concentration of 15.2 µmol/l. Administration of Ps I (7 mg/kg, i.v.) followed by light exposure (80 J/cm2) markedly suppressed the growth of xenograft tumors, and the tumor volume was 10-fold smaller than that of the control group. Tumor growth inhibition in vitro and in vivo had an obvious dependency on the Ps I concentration and irradiation dose. The mode of cell death post-Ps I-PDT was analyzed by flow cytometry, confocal laser scanning microscopy, and electron microscope, and the results suggested that apoptosis was the primary mode of HeLa cell death induced by Ps I-PDT. The results also demonstrated that tumor targeting of Ps I was clearly improved because of the endocytosis mediated by the folate receptor. As a result, Ps I-PDT exhibited higher antitumor activity than Ps A-PDT and has potential as an alternative treatment modality for cervical cancer.

Abstract
The majority of drugs and biomolecules need to be delivered into cells to be effective. However, the cell membranes, a biological barrier, strictly resist drugs or biomolecules entering cells, resulting in significantly reduced intracellular delivery efficiency. To overcome this barrier, a variety of intracellular delivery approaches including chemical and physical ways have been developed in recent years. In this review, the focus is on summarizing the nanomaterial routes involved in making use of a collection of receptors for the targeted delivery of drugs and biomolecules and the physical ways of applying micro- and nanotechnologies for high-throughput intracellular delivery.

Abstract
Polymeric micelles are among the most promising delivery systems in nanomedicine. The growing interest in polymeric micelles as drug delivery vehicle is promoted by the advantages they offer for hydrophobic anticancer agents. The size of most polymeric micelles lies within the range 10–100 nm ensuring that they can selectively leave the circulation at tumor site via the enhanced permeability and retention effect. Their unique structure allows them to solubilize hydrophobic drugs, prolongs their circulatory half-life and eventually leads to enhanced therapeutic efficacy. In addition, they can undergo several structural modifications to further augment tumor cell uptake. In this review, we will discuss various micellar systems that have been studied in preclinical and clinical settings.

Abstract
Polymer-based nanomedicine is a large and fast growing field. Polymer-based systems have been extensively used as therapeutic carriers as well as bioimaging agents for example in tumour diagnosis. However, fewer polymeric systems have been able to combine both therapy and imaging in a new field that is called theranostics (theragnostics). This review aims to summarise the recent developments and trends on polymeric theranostics. Four different types of therapies/treatments are examined namely drug delivery, gene delivery, photodynamic therapy and hyperthermia treatment combined with different imaging moieties like magnetic resonance imaging agents, fluorescent agents and microbubbles for ultrasound imaging.

Abstract
As versatile drug delivery systems, polymeric micelles have demonstrated particular strength in solubilizing hydrophobic anticancer drugs while eliminating the use of toxic organic solvents and surfactants. However, the true promise of polymeric micelles as drug carriers for cancer therapy resides in their potential ability to preferentially elevate drug exposure in the tumor and achieve enhanced anticancer efficacy, which still remains to be fully exploited. Here, we review various micellar constructs that exhibit the enhanced permeation and retention effect in the tumor, the targeting ligands that potentiate the anticancer efficacy of micellar drugs, and the polyplex micelle systems suitable for the delivery of plasmid DNA and small interference RNA. Together, these preclinical studies in animal models help us further explore polymeric micelles as emerging drug carriers for targeted cancer therapy.
