Endoplasmic reticulum-targeted phototherapy using one-step synthesized trace metal-doped carbon-dominated nanoparticles: Laser-triggered nucleolar delivery and increased tumor accumulation. Acta Biomater 2019; 88:462-476. [PMID: 30735810 DOI: 10.1016/j.actbio.2019.02.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 01/03/2019] [Accepted: 02/04/2019] [Indexed: 12/22/2022]
Abstract
Lysosomal entrapment and liver accumulation are the two main obstacles faced by many anticancer drugs for achieving satisfactory therapeutic outcomes. Here, we develop a facile one-step hydrothermal synthetic route to prepare trace metal (M)-, N-, and O-doped carbon-dominated nanoparticles (termed as MNOCNPs, M = Ni, Pd, or Cu, metal content: <0.1 mol%) with exceptional photothermal properties (e.g., the ultrahigh extinction coefficient of 32.7 L g-1 cm-1), which can simultaneously realize preferable endoplasmic reticulum (ER) targeting and specific tumor enrichment without noticeable liver accumulation after poly(ethylene glycol) (PEG) conjugation. More interestingly, the PEG-modified MNOCNPs with nanoscale lengths exhibit considerable nucleolar delivery and increased tumor accumulation upon laser irradiation. After fluorescence labeling, these PEG-modified MNOCNPs are suitable for fluorescence/photoacoustic/thermal triple-modal imaging-guided photothermal cancer treatment. Additionally, the ultralow metal content ensures the exceptional biosafety of the nanoagents. The present work provides a novel, facile, and general synthetic method of carbon-dominated nanoparticles with superior photothermal properties for highly efficient tumor ablation, and the large-organelle (ER and nucleus)-targeted cancer therapeutic strategy may represent an alternative solution for optimizing the anticancer efficacy of nanomaterials. STATEMENT OF SIGNIFICANCE: Limited wire-like nanomaterials have been used for biomedical applications due to their lack of intrinsic photothermal properties, poor cellular uptake and tumor accumulation, and potential biotoxicity arising from their micrometer lengths and/or massive heavy metal doping. Besides, the clinical applications of many nanoagents are hindered by their tendency to accumulate in liver, which may cause severe liver toxicity. Herein, we develop for the first time a one-step hydrothermal method to prepare wire-like trace metal-, N-, and O-doped carbon-dominated nanoparticles with excellent photothermal properties, massive cellular uptake, preferable ER localization, selective tumor targeting with negligible liver deposition, laser irradiation-enhanced nucleolar delivery and tumor accumulation, and multimodal imaging-guided cancer therapy. This work opens a new window for simultaneously overcoming lysosomal entrapment and liver accumulation in cancer therapy.

Abstract
The right choice of a fluorescent probe is essential for successful luminescence imaging and sensing and especially concerning in vivo and in vitro applications, the development of new classes have gained more and more attention in the last years. One of the most promising class are upconversion nanoparticles (UCNPs)-inorganic nanocrystals capable to convert near-infrared light in high energy radiation. In this review we will compare UCNPs with other fluorescent probes in terms of (a) the optical properties of the probes, such as their brightness, photostability and excitation wavelength; (b) their chemical properties such as the dispersibility, stability under experimental or physiological conditions, availability of chemical modification strategies for labelling; and (c) the potential toxicity and biocompatibility of the probe. Thereby we want to provide a better understanding of the advantages and drawbacks of UCNPs and address future challenges in the design of the nanocrystals.

Abstract
Breast tumor heterogeneity is responsible for the death of ~ 40,000 women in 2017 in USA. Triple-negative breast cancers (TNBCs) are very aggressive and it is the only breast cancer subgroup still lacking effective therapeutic. As a result, early stage detection of TNBC is vital and it will have huge significant in the clinics. Driven by the need, here we report the design of highly crystalline antibody-conjugated multifunctional multicolor luminescence nanosystem derived from naturally available popular tropical fruits mango and prune, which have capability to track breast cancer heterogeneity via selective separation and accurate identification of TNBC and HER-2 (+) or ER/PR (+) breast cancer cells selectively and simultaneously. A detailed synthesis and characterization of multifunctional multicolor nanosystems from tropical fruits has been reported. Experimental results show that by changing the fruits, multicolor luminescent carbon dots (LCDs) can be developed and is mainly due to the formation of highly crystalline nano dots with different heavy metal doping and also due to the presence of different types of surface functional groups. Experimental data presented show that multifunctional multicolor nanoprobe can be used for highly selective and simultaneous capturing of targeted TNBCs, HER2(+) or ER(+) breast cancer cells and the capture efficiency can be as high as 98%. Reported data indicate that multicolor fluorescence imaging can be used for mapping hetergenous breast cancer cells simultaneously, and it can distinguish targeted TNBCs from non-targeted HER-2 (+) or ER/PR (+) breast cancer. Our finding suggests excellent possibility of designing multicolor nanosystems from natural fruits for tracking cancer heterogeneity in clinics.

Abstract
In this work, we presented ternary nanoparticles [poly(carboxybetaine methacrylate) (pCBMA)(peptide dendrimer-modified carbon dots (CD-D)/doxorubicin (DOX))] based on peptide dendritic carbon dots (CDs) to realize tumor-specific drug delivery and highly efficient cancer therapy. The versatile nanoparticles could achieve "stealth" delivery in blood due to the antifouling zwitterion coating. Meanwhile, charge changes of the zwitterions could be moderated during their transportation toward/inside tumor cells, where subtle environmental pH variations acted as potent stimuli to actualize desired functions. In particular, the detachment of the zwitterionic "coat" at the tumor site resulted in the exposure of abundant peripheral guanidine groups on peptide dendritic carbon dots (CD-D/DOX) owing to the extracellular pH environment (pH 6.8)-induced charge conversion. Consequently, the positively charged CD-D/DOX (+7.02 mV) interacted with the negatively charged cancer cell membrane to enhance cellular uptake. After endocytosis, tumor intracellular microenvironments (acidic conditions and high glutathione (GSH) levels) could lead to effective disintegration of the CD-D/DOX entities due to acid-induced protonation of guanidine groups and glutathione-induced cleavage of peptide dendritic components on CDs, and then effective endosomal escape and fast doxorubicin hydrochloride (DOX·HCl) release (73.2% accumulative release within 4 h) were achieved successively. This strategy enabled a 9.19-fold drug release rate at tumor sites in comparison with the one in the physiological environment. Moreover, the excellent fluorescence properties of CDs endowed the pCBMA(CD-D/DOX) with fluorescence bioimaging function. In view of the above-mentioned advantages, pCBMA(CD-D/DOX) exhibited outstanding antitumor activities both in vitro and in vivo, demonstrating much higher antitumor efficacy and less side effects than the free DOX·HCl.

Abstract
Carbon quantum dots (CQDs) are a member of carbon nanostructures family which have received increasing attention for their photoluminescence (PL), physical and chemical stability and low toxicity. The classical semiconductor quantum dots (QDs) are semiconductor particles that are able to emit fluorescence by excitation. The CQDs is mainly referred to photoluminescent carbon nanoparticles less than 10 nm, with surface modification or functionalization. Contrary to other carbon nanostructures, CQDs can be synthesized and functionalized fast and easily. The fluorescence origin of the CQDs is a controversial issue which depends on carbon source, experimental conditions, and functional groups. However, PL emissions originated from conjugated π-domains and surface defects have been proposed for the PL emission mechanisms of the CQDs. These nanostructures have been used as nontoxic alternatives to the classical heavy metals containing semiconductor QDs in some applications such as in-vivo and in-vitro bio-imaging, drug delivery, photosensors, chemiluminescence (CL), and etc. This paper will introduce CQDs, their structure, and PL characteristics. Recent advances of the application of CQDs in biotechnology, sensors, and CL is comprehensively discussed.

Abstract
Integration of multiple diagnostic/therapeutic modalities into a single system with ultrasmall size, excellent photothermal/photodynamic properties, high cellular uptake efficiency, nuclear delivery capacity, rapid renal clearance, and good biosafety is highly desirable for cancer theranostics, but still remains challenging. Here, a novel type of multifunctional nanodots (denoted as BCCGH) was synthesized by mixing bovine serum albumin, carbon dots, and metal ions (Cu2+ and Gd3+), followed by the conjugation with a photosensitizer (HPPH). The nanodots hold great promise for fluorescence/photoacoustic/magnetic resonance/photothermal imaging-guided synergistic photothermal/photodynamic therapy (PDT) because of their appealing properties such as high photothermal conversion efficiency (68.4%), high longitudinal relaxivity (11.84 mM-1 s-1, 7 T), and superior colloidal stability with negligible Gd3+ release. Benefiting from the massive cellular uptake, endoplasmic reticulum/mitochondrion-targeting ability, and mild near-infrared laser irradiation-promoted nuclear delivery of BCCGH, a high anticancer therapeutic efficiency is achieved in the subsequent in vitro PDT. Besides, as revealed by the in vivo/ex vivo results, the nanodots also exhibit excellent tumor accumulation, efficient renal clearance, complete tumor ablation, and exceptional biosafety. To summarize, this work develops a carbon dot-mediated and albumin-based synthetic approach for constructing ultrasmall and multifunctional nanodots, which may hold great potential for cancer theranostics and beyond.

Abstract
Integrating the optical properties of near-infrared fluorescent carbon dots into liposomes may construct a multifunctional nano-system with the potential as a drug carrier, tracer and efficacy intensifier of the anticancer agent. In this study, the liposomes loaded with hydrophilic near-infrared carbon dots as a nano-carrier and tracer of lipophilic anticancer agent cinobufagin were developed. Prepared liposomes were characterized by particle size, morphology and entrapment efficiency. The drug release behavior, the tracer function, the anticancer effect and the side effect were investigated in vitro and in vivo. It was observed that the photoluminescence emission of carbon dots could be strongly enhanced up to 5 times by nano-liposomes. Due to this property, the bio-imaging of CDs + CB liposomes in vitro and in vivo could be clearly obtained. Our results also showed that the CDs + CB liposomes could be uptaken by cells (the lysosomes targeted) and delivered to the tumor site, and undoubtedly, the CDs + CB liposomes demonstrated sustained drug release, enhanced anticancer efficacy and low side effects in vivo. With the assistance of imaging function of CDs, the CDs + CB liposomes can easily display the distribution of drugs, which is very helpful for drug development and may open a novel avenue for drug delivery.

Abstract
Mitochondria-targeted cancer phototherapy (PT), which works by delivering photoresponsive agents specifically to mitochondria, is a powerful strategy to improve the phototherapeutic efficiency of anticancer treatments. Mitochondria play an essential role in cellular apoptosis, and are relevant to the chemoresistance of cancer cells. Furthermore, mitochondria are a major player in many cellular processes and are highly sensitive to hyperthermia and reactive oxygen species. Therefore, mitochondria serve as excellent locations for organelle-targeted phototherapy. In this review, we focus on the recent advances of mitochondria-targeting materials for mitochondria-specific PT. The combination of mitochondria-targeted PT with other anticancer strategies is also summarized. In addition, we discuss both the challenges currently faced by mitochondria-based cancer PT and the promises it holds.

Abstract
Being a typical copper-containing oxidase, tyrosinase plays critical roles in biological activity, and its aberrant expression might cause diverse skin diseases. Herein, we, for the first time, have found an interesting green fluorogenic reaction between methyldopa and ethanolamine. By combining transmission electron microscopy, UV-vis absorption spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and MALDI-TOF mass spectrum analysis, we have confirmed that there is a reliable method for preparing the bright green fluorescent polymethyldopa nanoparticles (PMNPs) by simply mixing methyldopa and ethanolamine at room temperature. Inspired by such a simple and convenient fluorogenic reaction, a novel polymethyldopa nanoparticles-based fluorescent sensor for detection of tyrosinase activity was developed by using the commercially available metyrosine as a substrate, accompanied by the tyrosinase-catalyzed specific conversion of metyrosine into methyldopa. According to the intrinsic sensitivity/selectivity of fluorescence technology and unambiguous response mechanism, our fluorescent sensor exhibits excellent sensing performance and can be utilized in the determination of the tyrosinase activity in real biological samples and inhibitor screening.

Abstract
Carbon quantum dots (CQDs) doped with phosphorus and nitrogen were prepared via a hydrothermal method starting from citric acid, urea and phosphoric acid in dimethylformamide solution. The size, morphology, surface composition, energy levels, and optical properties of the CQDs were characterized. They show both green down-conversion and up-conversion fluorescence. Ferric ions (Fe3+) are found to quench the fluorescence. Cyclic voltammetry was used to identify the HOMO and LUMO levels of the doped CQDs. The quenching mechanism, as confirmed by energy level calculations and absorption spectra, can be attributed to the selective coordination of Fe3+ by the surface functional groups on the CQDs. This facilitates the photo-induced electron transfer from the CQDs to the d orbitals of Fe3+. The CQDs are shown to be viable fluorescent probes for determination of Fe3+ with high selectivity and sensitivity. The assay has a linear response in the 0.1 μM to 0.9 μM Fe3+ concentration range and a 50 nM as limit of detection (at a S/N ratio of 3). Graphical abstract Fluorescence probe for determination of ferric ions based on carbon quantum dot quenching via chelation facilitate photo-electron transfer.

Abstract
INTRODUCTION Interest in mesoporous silica nanoparticles for drug delivery has resulted in a good understanding of the impact of size and surface chemistry of these nanoparticles on their performance as drug carriers. Shape has emerged as an additional factor that can have a significant effect on delivery efficacy. Rod-shaped mesoporous silica nanoparticles show improvements in drug delivery relative to spherical mesoporous silica nanoparticles. AREAS COVERED This review summarises the synthesis methods for producing rod-shaped mesoporous silica nanoparticles for use in nanomedicine. The second part covers recent progress of mesoporous silica nanorods by comparing the impact of sphere and rod-shape on drug delivery efficiency. EXPERT OPINION As hollow mesoporous silica nanorods are capable of higher drug loads than most other drug delivery vehicles, such particles will reduce the amount of mesoporous silica in the body for efficient therapy. However, the importance of nanoparticle shape on drug delivery efficiency is not well understood for mesoporous silica. Studies that visualize and quantify the uptake pathway of mesoporous silica nanorods in specific cell types and compare the cellular uptake to the well-studied nanospheres should be the focus of research to better understand the role of shape in uptake.

Abstract
Tumor growth and metastasis are two main causes of cancer-related deaths. Here, we simultaneously investigated the effects of nanoparticles on cancer cell viability and migration using polyethylene glycol (PEG)-modified, platinum-doped (<4 mol %) carbon nanoparticles (denoted as PEG-PtCNPs). The bare PtCNPs were prepared by the facile one-step hydrothermal treatment of p-phenylenediamine and K2PtCl4 in aqueous solution. After PEGylation, the obtained PEG-PtCNPs can serve as an excellent photothermal nanoagent for cell migration inhibition, laser-triggered nuclear delivery, effective tumor accumulation, and imaging-guided tumor ablation with improved therapeutic efficacy and reduced side effects. In the absence of laser exposure, the positively charged PEG-PtCNPs with a hydrodynamic diameter of ∼19 nm easily entered the cells by endocytosis and were located in multiple organelles (including mitochondrion, endoplasmic reticulum, lysosome, and Golgi apparatus), causing a slight increase in the expression level of nuclear protein lamin A/C. Upon mild laser irradiation (0.3 W cm-2), the fragmented cytoskeletal structures and overexpression of lamin A/C were observed, thus inhibiting cancer cell migration. Furthermore, hyperthermia induced by PEG-PtCNPs plus laser irradiation at a higher power density (1.0 W cm-2) could cause irreversible damage to the nuclear membranes and then facilitate the nuclear delivery of the nanoagents without the introduction of nuclear targeting ligands. Taken together, this work develops a facile synthetic approach of platinum-based carbon nanoparticles with excellent photothermal properties, and demonstrates their potential applications for modulating tumor metastasis and realizing multi-organelle-targeted tumor ablation.

Abstract
Organelles play crucial roles in cellular activities and the functions of organelles are related greatly to the pH values, therefore, the bio-imaging of targeted organelles and their related pH sensing is of great importance in biological assays. Herein we report the fluorescence imaging of specific organelles, i.e., lysosomes and endoplasmic reticulum, and their pH sensing with surface regulated carbon dots (CDs). Carbon dots functionalized with amine groups (ACDs) are first prepared by hydrothermal treatment of citric acid and urea, and then laurylamine functionalized CDs (LCDs) are obtained via the conjugation of laurylamine with ACDs. The as-prepared ACDs and LCDs provide clear and bright imaging results for the lysosome and endoplasmic reticulum, respectively. The subcellular targeting features of the two CDs are attributed to their surface chemistries and cellular uptake pathways. Moreover, both the CDs are pH responsive within a certain pH range, i.e., 4.0-5.4 for ACDs and 6.2-7.2 for LCDs. The ACDs and LCDs are thus successfully applied to visualize the pH fluctuations of the lysosome and endoplasmic reticulum in MCF-7 cells.
