Current Strategies to Enhance Delivery of Drugs across the Blood–Brain Barrier. Pharmaceutics 2022; 14:pharmaceutics14050987.

Abstract
The blood–brain barrier (BBB) has shown to be a significant obstacle to brain medication delivery. The BBB in a healthy brain is a diffusion barrier that prevents most substances from passing from the blood to the brain; only tiny molecules can pass across the BBB. The BBB is disturbed in specific pathological illnesses such as stroke, diabetes, seizures, multiple sclerosis, Parkinson’s disease, and Alzheimer’s disease. The goal of this study is to offer a general overview of current brain medication delivery techniques and associated topics from the last five years. It is anticipated that this review will stimulate readers to look into new ways to deliver medications to the brain. Following an introduction of the construction and function of the BBB in both healthy and pathological conditions, this review revisits certain contested questions, such as whether nanoparticles may cross the BBB on their own and if medications are selectively delivered to the brain by deliberately targeted nanoparticles. Current non-nanoparticle options are also discussed, including drug delivery via the permeable BBB under pathological circumstances and the use of non-invasive approaches to improve brain medication absorption.

Abstract
Polylysine and materials that integrate lysine form promising drug delivery platforms. As a cationic macromolecule, a polylysine polymer electrostatically interacts with cells and is efficiently internalized, thereby enabling intracellular delivery. Although polylysine is intrinsically pH-responsive, the conjugation with different functional groups imparts smart, stimuli-responsive traits by adding pH-, temperature-, hypoxia-, redox-, and enzyme-responsive features for enhanced delivery of therapeutic agents. Because of such characteristics, polylysine has been used to deliver various cargos such as small-molecule drugs, genes, proteins, and imaging agents. Furthermore, modifying contrast agents with polylysine has been shown to improve performance, including increasing cellular uptake and stability. In this review, the use of lysine residues, peptides, and polymers in various drug delivery systems has been discussed comprehensively to provide insight into the design and robust manufacturing of lysine-based delivery platforms.

Abstract
According to World Health Organization (WHO) cancer is the second most important cause of death globally. Because angiogenesis is considered as an essential process of growth, proliferation and tumor progression, within this review we decided to shade light on recent development of chemical compounds which play a significant role in its imaging and monitoring. Indeed, the review gives insight about the current achievements of active agents structures involved in imaging techniques such as: positron emission computed tomography (PET), magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT), as well as combination PET/MRI and PET/CT. The review aims to provide the journal audience with a comprehensive and in-deep understanding of chemistry policy in tumor angiogenesis imaging.

Abstract
Magnetic resonance imaging (MRI) contrast agents (CAs) have drawn increasing attention in cancer diagnosis. However, since the signals they generate are always "on" and may bring interfering background signals to the region of interest, their selectivity and sensitivity need further improvement. Herein, extremely small iron oxide nanoparticles (ESIONPs) conjugated through a disulfide bond with polyethylene glycol (PEG) that is terminally modified with folic acid (FA), namely ESIONPs-s-s-PEG-FA, were designed and synthesized to target tumor tissues and selectively activate the T2 MRI contrast effect in the reducing environment of tumor cells. Due to the breakage of disulfide bonds by the high glutathione (GSH) concentration in tumor cells, the hydrophilic PEG chains detached from the surface of ESIONPs, which led to the aggregation of ESIONPs and the activation of the T2 contrast effect. In vitro results showed that ESIONPs-s-s-PEG-FA could effectively target tumors to assemble in the reductive environment and switch from a T1 contrast agent (CA) to a T2 one. Furthermore, MRI in tumor-bearing mice also indicated the obvious targeting capacity and the "turn on" of the T2 contrast effect. In addition, the results of the biosafety assay suggest that the tumor-targeted T1/T2 switchable CA is equipped with favorable biocompatibility for cancer diagnosis.

Abstract
Double-hydrophilic block copolymers (DHBCs), consisting of at least two different water-soluble blocks, are an alternative to the classical amphiphilic block copolymers and have gained increasing attention in the field of biomedical applications. Although the chemical nature of the two blocks can be diverse, most classical DHBCs consist of a bioeliminable non-ionic block to promote solubilization in water, like poly(ethylene glycol), and a second block that is more generally a pH-responsive block capable of interacting with another ionic polymer or substrate. This second block is generally non-degradable and the presence of side chain functional groups raises the question of its fate and toxicity, which is a limitation in the frame of biomedical applications. In this review, following a first part dedicated to recent examples of non-degradable DHBCs, we focus on the DHBCs that combine a biocompatible and bioeliminable non-ionic block with a degradable functional block including polysaccharides, polypeptides, polyesters and other miscellaneous polymers. Their use to design efficient drug delivery systems for various biomedical applications through stimuli-dependent self-assembly is discussed along with the current challenges and future perspectives for this class of copolymers.

Abstract
OBJECTIVE We try to establish designs for the macromolecular agents possessing high Gd3+-chelating stability, because free Gd3+ ion released from Gd chelates is known as a risk factor to cause toxic side effects and a safety concern. MATERIALS AND METHODS We prepared three types of Gd-based macromolecular MRI contrast agents from a synthetic polymer (poly(glutamic acid) homopolymer or poly(ethylene glycol)-b-poly(lysine) block copolymer) and a chelating moiety (DO3A or DOTA) having two strategic designs for high chelate stability. Then, we examine the in vitro Gd3+-chelate stability of these macromolecular MRI contrast agents. RESULTS The prepared macromolecular agents exhibited the same or higher Gd3+-chelate stability as/than did Gd-DOTA that possesses the highest Gd3+-chelate stability among the approved small-MW Gd-chelate MRI contrast agent. DISCUSSION Our macromolecular design was considered to work well for high Gd3+-chelate stability.

Abstract
Background:The main issue is finding the most efficient method in the treatment of cancer in terms of early and accurate diagnostic. One of the most modern diagnostic techniques is imaging methods. The accuracy and detection speed of MRI and CT SCAN are high.Methods:The most important complication of iodinated contrast agents in medical imaging is severe renal toxicity Nephrogenic Systemic Fibrosis (NSF). In order to reduce the cytotoxicity of kidney cells caused by the usage of iodized contrast agents a complex agent should be designed. The two drugs which have been used for the synthesis of this compound are L -lysine amino acid and NAcetyl- Cysteine (NAC).Results:The synthesis of this complex due to two dimer molecules with each other and NAC greatly a helper for an antioxidant activity and L-lysine amino acid helps in drug entry into the cells. However, helping for an antioxidant activity heavily reinforce and eventually will successfully reduce the cytotoxicity. When its exposure to HEK 293 cell line (P<0.05). The reduction in toxicity at the dosage of 100 µM has been showed as the greatest reduction. The amount of renal toxicity was reported 40% in Omniscan.Conclusion:Omniscan was tested when iodinated contrast medium was combined with the synthesized 2NAC-LYS-OMNISCAN complex and the human embryonic kidney 293 (HEK293) cell line. Then, the cytotoxicity was reduced to 10 %. On the other hand, the viability increased from 60 % to 90 %, or in other words, the cytotoxicity was reduced from 40 % to 10 %.

Abstract
Polymeric-micelle carrier systems have emerged as a novel drug-carrier system and have been actively studied for anticancer drug targeting. In contrast, toxicological and immunological concerns related to not only polymeric-micelle carrier systems, but also other nanocarrier systems, have received little attention owing to researchers' focus on therapeutic effects. However, in recent clinical contexts, biopharmaceuticals' effects on immune responses have come to light, requiring that researchers substantively explore the potential negative side effects of nanocarrier systems and of therapeutic proteins in order to develop nanocarrier systems suitable for clinical use. The present review describes current insights into both toxicological and immunological issues regarding polymeric-micelle carrier systems. The review focuses on immunogenicity issues of polymeric-micelle carrier systems possessing poly(ethylene glycol) (PEG). We conclude that PEG-related immunogenicity is deeply related to characteristics of a counterpart block of PEG-conjugates, and we propose future directions for addressing this unresolved issue.

Abstract
Combating melanoma via topical route is a highly challenging task due to low selectivity, poor efficacy and impeding biological environment of the skin. In the present study, we engineered a chitosan based pH responsive biodegradable nanogel (FCNGL), encapsulated with 5-FU that was effective even at very low drug doses (0.2% w/v) against melanoma. The FCNGL was synthesized by ion gelation technique exhibited nano-size particle distribution and sustained drug release kinetics. Hemolysis and coagulation analysis revealed high safety whereas MTT and apoptosis assays exhibited the efficacy of FCNGL. DMBA-Croton oil Swiss albino mice model was employed for in vivo assessment followed by gamma scintigraphic screening. Tumor burden and pharmacokinetic antioxidant stress levels along with whole-body gamma scintigraphy imaging using 99 mTc labelled nanogel exhibited selective accumulation in melanoma tumor nodules. The pH responsive behaviour of the nanogels resulted in triggered release of 5-FU in slightly acidic microenvironment, resulting in selective drug accumulation at the melanoma site. Immunohistochemistry (IHC) analysis of tumor showed improvement of subcutaneous layer alignment and regeneration of the epithelial skin layer when compared with standard 5% 5-FU and control mice group. Overall our preclinical data using the FCNGL portends to be a promising platform for efficient and sustained delivery of 5-FU for topical chemotherapy that can result in high efficacy, patient compliance and safety in the clinical set up.

Abstract
The blood-brain barrier (BBB) has been a great hurdle for brain drug delivery. The BBB in healthy brain is a diffusion barrier essential for protecting normal brain function by impeding most compounds from transiting from the blood to the brain; only small molecules can cross the BBB. Under certain pathological conditions of diseases such as stroke, diabetes, seizures, multiple sclerosis, Parkinson's disease and Alzheimer disease, the BBB is disrupted. The objective of this review is to provide a broad overview on current strategies for brain drug delivery and related subjects from the past five years. It is hoped that this review could inspire readers to discover possible approaches to deliver drugs into the brain. After an initial overview of the BBB structure and function in both healthy and pathological conditions, this review re-visits, according to recent publications, some questions that are controversial, such as whether nanoparticles by themselves could cross the BBB and whether drugs are specifically transferred to the brain by actively targeted nanoparticles. Current non-nanoparticle strategies are also reviewed, such as delivery of drugs through the permeable BBB under pathological conditions and using non-invasive techniques to enhance brain drug uptake. Finally, one particular area that is often neglected in brain drug delivery is the influence of aging on the BBB, which is captured in this review based on the limited studies in the literature.

Gold nanocage decorated pH-sensitive micelle for highly effective photothermo-chemotherapy and photoacoustic imaging. Acta Biomater 2017; 64:223-236. [PMID: 29030300 DOI: 10.1016/j.actbio.2017.10.018] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2017] [Revised: 10/07/2017] [Accepted: 10/09/2017] [Indexed: 01/11/2023]
Abstract
A pH-sensitive copolymer PAsp(DIP)-b-PAsp(MEA) (PDPM) was synthesized and self-assembled to micelle loading chemotherapeutic drug doxorubicin (DOX) and introducing a gold nanocage structure for photothermo-chemotherapy and photoacoustic imaging. After further surface modification with polyethylene glycol (PEG), the DOX-loaded pH-sensitive gold nanocage (D-PGNC) around 100 nm possessed a uniform spherical structure with a pH-sensitive core of PAsp(DIP) incorporating DOX, an interlayer crosslinked via disulfide bonds and decorated with discontinuous gold shell, and a PEG corona. The release of DOX from D-PGNC was turned off in bloodstream due to the cross-linking and gold decoration of interlayer but turned on inside tumor tissue by multiple stimulations including the low pH value of tumor tissue (≈6.8), the low lysosomal pH value of cancer cells (≈5.0) and near-infrared (NIR) irradiation. The gold nanocage receiving NIR irradiation could generate hyperthermia to ablate tumor cells. Moreover, the photoacoustic (PA) imaging and analysis of DOX fluorescence inside tumor tissue demonstrated that photothermal therapy based on the gold nanocage effectively drove DOX penetration inside tumor. Owing to the rapid intratumor release and deep tissue penetration of drug favorable for killing cancer cells survived the photothermal therapy, the combined therapy based on D-PGNC via NIR irradiation exhibited a synergistic treatment effect superior to either chemotherapy or NIR-induced photothermal therapy alone. STATEMENT OF SIGNIFICANCE The novelty of the manuscript is its multifunctional system which incorporates anticancer drug DOX in its pH-sensitive core and acts as a template to introduce a gold nanocage. This nanomedicine presents potentials of sequestrating drug molecules in blood circulation but releasing them inside tumor upon responding to the acidic microenvironment therein. Exposure to NIR laser further expedited the pH-sensitive DOX release and promoted DOX penetration into cancer tissues far away from the vasculature. Consequently, the combined photothermo-chemotherapy showed synergistic effects to inhibit tumor growth and prolong animal survival in nude mice bearing human SKOV-3 ovarian tumor. Moreover, owing to the decoration with gold nanocage, the tumor accumulation and intratumor diffusion of the micelles were easily trackable using photoacoustic imaging.

Abstract
Rapidly developing polymeric micelles as potential targeting carriers has intensified the need for better understanding of the underlying principles related to the selection of suitable delivery materials for designing, characterizing, drug loading, improving stability, targetability, biosafety and efficacy. The emergence of advanced analytical tools such as fluorescence resonance energy transfer and dissipative particle dynamics has identified new dimensions of these nanostructures and their behavior in much greater details. This review summarizes recent efforts in the development of polymeric micelles with respect to their architecture, formulation strategy and targeting possibilities along with their preclinical and clinical aspects. Literature of the past decade is discussed critically with special reference to the chemistry involved in the formation and clinical applications of these versatile materials. Thus, our main objective is to provide a timely update on the current status of polymeric micelles highlighting their applications and the important parameters that have led to successful delivery of drugs to the site of action.

Abstract
In this work, a novel type of block copolymer micelles with K+ -responsive characteristics for targeted intracellular drug delivery is developed. The proposed smart micelles are prepared by self-assembly of poly(ethylene glycol)-b-poly(N-isopropylacry-lamide-co-benzo-18-crown-6-acrylamide) (PEG-b-P(NIPAM-co-B18C6Am)) block copolymers. Prednisolone acetate (PA) is successfully loaded into the micelles as the model drug, with loading content of 4.7 wt%. The PA-loaded micelles display a significantly boosted drug release in simulated intracellular fluid with a high K+ concentration of 150 × 10-3 m, as compared with that in simulated extracellular fluid. Moreover, the in vitro cell experiments indicate that the fluorescent molecules encapsulated in the micelles can be delivered and specifically released inside the HSC-T6 and HepG2 cells responding to the increase of K+ concentration in intracellular compartments, which confirms the successful endocytosis and efficient K+ -induced intracellular release. Such K+ -responsive block copolymer micelles are highly potential as new-generation of smart nanocarriers for targeted intracellular delivery of drugs.

Abstract
Selective deposition of Gd(iii) ions onto the shell structure of complex micelles was achieved to yield Gd decorated hybrid micelles for integrated magnetic resonance imaging and drug delivery. The complex micelles were engineered by the hydrophilic-hydrophobic self-assembly of two kinds of amphiphilic polymers, pluronic F127 and a peptide-amphiphile (PA), via a facile, environmentally benign strategy. These core-shell complex micelles provide a robust multifunctional platform for theranostic applications. The hydrophobic core of micelles allows us to compartmentalize anti-cancer drugs, while the shell structure with a mixed poly(ethylene-oxide) (PEO) and peptide composition provides chelation capacity for the MRI contrast agent Gd(iii). The nanoscaled hybrid micelles are not only developed to address the challenges of small molecular Gd(iii)-chelates, but also be integrated with the capability of anticancer drug delivery for tumor therapy. More importantly, a synergy effect was observed such that the coordination effect of Gd(iii) with the shell enhanced the micellar stability and retarded the DOX release behavior. In vitro and in vivo experiments of MRI contrast enhancement and therapy clearly evidenced that the DOX loaded hybrid micelles can serve as efficient theranostic agents.

Abstract
Gadolinium-based contrast agents are extensively used as magnetic resonance imaging (MRI) contrast agents due to their outstanding signal enhancement and ease of chemical modification. However, it is increasingly recognized that information obtained from single modal molecular imaging cannot satisfy the higher requirements on the efficiency and accuracy for clinical diagnosis and medical research, due to its limitation and default rooted in single molecular imaging technique itself. To compensate for the deficiencies of single function magnetic resonance imaging contrast agents, the combination of multi-modality imaging has turned to be the research hotpot in recent years. This review presents an overview on the recent developments of the functionalization of gadolinium-based contrast agents, and their application in biomedicine applications.

Abstract
Liposomes are spherical, self-closed structures formed by lipid bilayers that can encapsulate drugs and/or imaging agents in their hydrophilic core or within their membrane moiety, making them suitable delivery vehicles. We have synthesized a new liposome containing gadolinium-DOTA lipid bilayer, as a targeting multimodal molecular imaging agent for magnetic resonance and optical imaging. We showed that this liposome has a much higher molar relaxivities r1 and r2 compared to a more conventional liposome containing gadolinium-DTPA-BSA lipid. By incorporating both gadolinium and rhodamine in the lipid bilayer as well as biotin on its surface, we used this agent for multimodal imaging and targeting of tumors through the strong biotin-streptavidin interaction. Since this new liposome is thermosensitive, it can be used for ultrasound-mediated drug delivery at specific sites, such as tumors, and can be guided by magnetic resonance imaging.

Abstract
The ion exchange intercalation of two Gd-based magnetic resonance imaging contrast agents into hydroxy double salts (HDSs) is reported. The presence of Gd(3+) diethylenetriaminepentaacetate and Gd(3+) diethylenetriaminepenta(methylenephosphonate) complexes in the HDS lattice after intercalation was confirmed by microwave plasma-atomic emission spectroscopy. The structural aspects of the HDS-Gd composites were studied by X-ray diffraction, with the intercalates having an interlayer spacing of 14.5-18.6 Å. Infrared spectroscopy confirmed the presence of characteristic vibration peaks associated with the Gd(3+) complexes in the intercalation compounds. The proton relaxivities of the Gd(3+) complex-loaded composites were 2 to 5-fold higher in longitudinal relaxivity, and up to 10-fold higher in transverse relaxivity, compared to solutions of the pure complexes. These data demonstrate that the new composites reported here are potentially potent MRI contrast agents.

Abstract
Since the 1990s, nanoscale drug carriers have played a pivotal role in cancer chemotherapy, acting through passive drug delivery mechanisms and subsequent pharmaceutical action at tumor tissues with reduction of adverse effects. Polymeric micelles, as supramolecular assemblies of amphiphilic polymers, have been considerably developed as promising drug carrier candidates, and a number of clinical studies of anticancer drug-loaded polymeric micelle carriers for cancer chemotherapy applications are now in progress. However, these systems still face several issues; at present, the simultaneous control of target-selective delivery and release of incorporated drugs remains difficult. To resolve these points, the introduction of stimuli-responsive mechanisms to drug carrier systems is believed to be a promising approach to provide better solutions for future tumor drug targeting strategies. As possible trigger signals, biological acidic pH, light, heating/cooling and ultrasound actively play significant roles in signal-triggering drug release and carrier interaction with target cells. This review article summarizes several molecular designs for stimuli-responsive polymeric micelles in response to variation of pH, light and temperature and discusses their potentials as next-generation tumor drug targeting systems.

Abstract
OBJECTIVES The objective of this study was to establish an efficient carrier for small interfering RNA (siRNA) delivery targeting pancreatic tumor cells. METHODS A copolymer consisting of a single-chain variable fragment targeted to human CD44 variant 6 (scFv(CD44v6)) functional group conjugated to polyethylene glycol-poly-L-lysine was synthesized and assembled into micelles encapsulating the siRNAs. Flow cytometry and Western blot assays were performed to evaluate the transfection efficiency and gene-silencing effect of the siRNAs. Afterward, (4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide, Transwell, soft agar colony formation, and enzyme-linked immunosorbent assays were performed to evaluate the biological functions of PANC-1 cells after Kirsten rat sarcoma viral oncogene knockdown. In vivo assays were performed using a BALB/c (nu/nu) mouse model subcutaneously injected with PANC-1 xenografts. Real-time in vivo fluorescence imaging was used to monitor the tumor homing of the nanoparticles. RESULTS The scFv(CD44v6) enabled more efficient delivery of siRNAs and exhibited enhanced gene silencing compared with nontargeted nanoparticles. Furthermore, targeted delivery of the siRNAs induced a potent inhibitory effect on cell proliferation, colony formation, invasion, and vascular endothelial growth factor production. The animal assays revealed that single-chain variable fragment nanoparticles accumulated in the tumor tissue and enhanced the inhibition of tumor growth in vivo. CONCLUSIONS The scFv(CD44v6)-conjugated nanocarriers provide a highly efficient and safe platform for systemic gene therapy for pancreatic cancer.

Abstract
Application of organic nanotubes (ONTs) into drug nanocarriers ultimately requires validation in live animals. For improving the dispersibility in biological media and in vivo distribution, the outer surface of an ONT was functionalized with polyethylene glycol (PEG) via the coassembly of an ONT-forming lipid with 5-20 mol% of a PEG-tethered lipid analogue (PEG-lipid). Firstly, the effect of PEGylation on the psysicochemical properties of ONTs, such as morphology and dispersibility, was investigated. PEGylation of ONTs slightly reduced the average length and effectively prevented the aggregation in phosphate-buffered saline (PBS). The PEGylated ONTs even showed high thermal stability in aqueous dispersion at least up to 95°C. Secondly, differential scanning calorimetry and powder X-ray diffraction indicated that ~10 mol% of PEG-lipid was completely incorporated into the ONTs, while 20 mol% of PEG-lipid encountered a partial phase separation during coassembly. In the heating differential scanning calorimetry runs, the resultant PEGylated ONTs with 5 mol% PEG-lipid showed no sign of phase separation up to 180°C under lyophilized condition, while those with 10 mol% and 20 mol% PEG-lipid showed some phase separation of the PEG-lipid above 120°C. Finally, PEGylation significantly affected the tissue distribution and prolonged the persistence time in the blood in mice. Non-PEGylated ONTs was quickly cleared from the circulation after intravenous infusion and preferentially accumulated in the lung, while PEGylated ONTs was mainly trapped in the liver and could circulate in the blood up to 24 hours. This study provided valuable information of physicochemical properties and the in vivo distribution behavior of PEGylated ONTs for their potential application into drug nanocarriers.

Abstract
The ability to efficiently deliver a drug or gene to a tumor site is dependent on a wide range of factors including circulation time, interactions with the mononuclear phagocyte system, extravasation from circulation at the tumor site, targeting strategy, release from the delivery vehicle, and uptake in cancer cells. Nanotechnology provides the possibility of creating delivery systems where the design constraints are decoupled, allowing new approaches for reducing the unwanted side effects of systemic delivery, increasing tumor accumulation, and improving efficacy. The physico-chemical properties of nanoparticle-based delivery platforms introduce additional complexity associated with pharmacokinetics, tumor accumulation, and biodistribution. To assess the impact of nanoparticle-based delivery systems, we first review the design strategies and pharmacokinetics of FDA-approved nanomedicines. Next we review nanomedicines under development, summarizing the range of nanoparticle platforms, strategies for targeting, and pharmacokinetics. We show how the lack of uniformity in preclinical trials prevents systematic comparison and hence limits advances in the field.

Abstract
Targeting to solid tumors is the most challenging issue in the drug delivery field. To obtain the ideal pharmacodynamics of administrated drugs, drug carriers must suppress drug release and interactions with non-target tissues while circulating in the bloodstream, yet actively release the incorporated drug and interact with target cells after delivery to the tumor tissue. To handle this situation, stimuli-responsive drug carriers are extremely useful, because carriers change their physicochemical properties to control the drug release rate and interaction with cells in response to the surrounding environmental conditions or applied physical signals. The current review focuses on the strategy and availability of temperature-responsive (TR) polymeric micelles as a next-generation drug carrier. In particular, we discuss the unique properties of TR polymeric micelles, such as temperature-triggered drug release and intracellular uptake system. In addition, we explore the methodology for integrating other targeting systems into TR micelles to pursue the ideal pharmacodynamics in conjunction with thermal therapy as a future prospective of the TR system.

Abstract
We developed Pyrene-Gadolinium (Py-Gd) nanoparticles as pH-sensitive magnetic resonance imaging (MRI) contrast agents capable of showing a high-Mr signal in cancer-specific environments, such as acidic conditions. Py-Gd nanoparticles were prepared by coating Py-Gd, which is a complex of gadolinium with pyrenyl molecules, with pyrenyl polyethyleneglycol PEG using a nano-emulsion method. These particles show better longitudinal relaxation time (T1) MR signals in acidic conditions than they do in neutral conditions. Furthermore, the particles exhibit biocompatibility and MR contrast effects in both in vitro and in vivo studies. From these results, we confirm that Py-Gd nanoparticles have the potential to be applied for accurate cancer diagnosis and therapy.
