Abstract
Well-defined amphiphilic polymers of the ABA and ABC type are synthesized, where A is poly(L-lysine hydrochloride) (PLL), B is poly(γ-benzyl-(d7) L-glutamate) (PBLG(-d7)), and C is poly(ethylene oxide) (PEO). The two polymers exhibit similar PBLG(-d7) composition, while in the ABC, the volume fraction of PEO block is higher than that of PLL. Both polymers form polymersomes in water. The polymersomes are loaded with doxorubicin or paclitaxel. It is found that in the ABC, due to asymmetry of the two hydrophilic blocks, PEO is always on the outer periphery and the dimensions of the vesicles are smaller. The release of the vesicles is temperature- and pH-dependent. In vivo toxicity tests of the empty vesicles show that they are not toxic. In vitro activity of the loaded vesicles against human pancreatic cancer cell lines reveals comparable activity to Myocet for the ABA loaded with doxorubicin, while lower activity is observed for the ABC.

Abstract
Quantum dots (QDs) are highly fluorescent and stable probes for cellular and molecular imaging. However, poor intracellular delivery, stability, and toxicity of QDs in biological compartments hamper their use in cellular imaging. To overcome these limitations, we developed a simple and effective method to load QDs into polymersomes (Ps) made of poly(dimethylsiloxane)-poly(2-methyloxazoline) (PDMS-PMOXA) diblock copolymers without compromising the characteristics of the QDs. These Ps showed no cellular toxicity and QDs were successfully incorporated into the aqueous compartment of the Ps as confirmed by transmission electron microscopy, fluorescence spectroscopy, and fluorescence correlation spectroscopy. Ps containing QDs showed colloidal stability over a period of 6 weeks if stored in phosphate-buffered saline (PBS) at physiological pH (7.4). Efficient intracellular delivery of Ps containing QDs was achieved in human liver carcinoma cells (HepG2) and was visualized by confocal laser scanning microscopy (CLSM). Ps containing QDs showed a time- and concentration-dependent uptake in HepG2 cells and exhibited better intracellular stability than liposomes. Our results suggest that Ps containing QDs can be used as nanoprobes for cellular imaging.

Abstract
In this study, glucose transporter and folic acid (FA) receptor-mediated Pluronic P105 polymeric micelles loaded with DOX (GF-DOX) were prepared for enhancing the blood-brain barrier (BBB) transportation and improving the drug accumulation in the glioma cells. The pH-triggered DOX release of GF-DOX indicating a comparatively fast drug release at weak acidic condition and stable state of the carrier at physiological environment. The transport of GF-DOX across the in vitro BBB model showed that GF-DOX exhibited higher BBB transportation ability with the transporting ratio of 21.47% in 4 h. The carrier was internalized into C6 glioma cells upon crossing the BBB model for the combined effect of the brain targeting by transportation of glucose transporter and active tumor cell targeting by FA receptor-mediated endocytosis. Moreover, minimized weight changes and high suppression ratio of tumor growth were observed after intravenous injection of GF-DOX. In conclusion, the glucose transporter and FA dual-targeting micelles would provide a safe and effective strategy for new modalities to treat brain tumor.

Abstract
To improve bone metastases chemotherapy, a peptide-conjugated diblock copolymer consisting of chimeric peptide, poly(ethylene glycol) and poly(trimethylene carbonate) (Pep-b-PEG-b-PTMC) is fabricated as a drug carrier capable of bone-seeking targeting as well as pathology-responsive charge reversal to ensure effective cellular uptake at the lesion sites. The chimeric peptide CKGHPGGPQAsp8 consists of an osteotropic anionic Asp8, a cathepsin K (CTSK)-cleavable substrate (HPGGPQ) and cationic residue tethered to polymer chain. Pep-b-PEG-b-PTMC can spontaneously self-assemble into negatively charged nanomicelles (~75 nm). As to the model drug of doxorubicin, Pep-b-PEG-b-PTM shows 30.0 ± 1 % and 90.1 ± 2 % for loading content and loading efficiency, respectively. High bone binding capability is demonstrated with that 66 % of Pep-b-PEG-b-PTMC micelles are able to bind to hydroxyl apatite, whereas less than 15 % is for Pep-free micelles. The nanomicelles exhibit a negative-to-positive charge conversion from -18.5 ± 1.9 mV to 15.2 ± 1.8 mV upon exposure to CTSK, an enzyme overexpressed in bone metastatic microenvironments. Such a pathology-responsive transition would lead to remarkably enhanced cellular uptake of the nanomicelles upon reaching lesion sites, thus improving the drug efficacy as verified by the in vitro cytotoxicity assay and the in vivo study in myeloma-bearing 5TGM1 mice model.

Abstract
Aliphatic polycarbonates were discovered a long time ago, with their conventional applications mostly limited to low molecular weight oligomeric intermediates for copolymerization with other polymers. Recent developments in polymerization techniques have overcome the difficulty in preparing high molecular weight aliphatic polycarbonates. These in turn, along with new functional monomers, have enabled the preparation of a wide range of aliphatic polycarbonates with diverse chemical compositions and structures. This review summarizes the latest polymerization techniques for preparing well-defined functional aliphatic polycarbonates, as well as the new applications of those aliphatic polycarbonates, esecially in the biomedical field.

Abstract
In this paper, a novel daunorubicin (DNR)-loaded MUC1 aptamer-near infrared (NIR) CuInS2 quantum dot (DNR-MUC1-QDs) conjugates were developed, which can be used as a targeted cancer imaging and sensing system. After the NIR CuInS2 QDs conjugated with the MUC1 aptamer-(CGA)7, DNR can intercalate into the double-stranded CG sequence of the MUC1-QDs. The incorporation of multiple CG sequences within the stem of the aptamers may further increase the loading efficiency of DNR on these conjugates. DNR-MUC1-QDs can be used to target prostate cancer cells. We evaluated the capacity of MUC1-CuInS2 QDs for delivering DNR to cancer cells in vitro, and its binding affinity to MUC1-positive and MUC1-negative cells. This novel aptamer functionalized QDs bio-nano-system can not only deliver DNR to the targeted prostate cancer cells, but also can sense DNR by the change of photoluminescence intensity of CuInS2 QDs, which concurrently images the cancer cells. The quenched fluorescence intensity of MUC1-QDs was proportional to the concentration of DNR in the concentration ranges of 33-88 nmol L(-1). The detection limit (LOD) for DNR was 19 nmol L(-1). We demonstrate the specificity and sensitivity of this DNR-MUC1-QDs probe as a cancer cell imaging, therapy and sensing system in vitro.

Abstract
We report the size-controlled self-assembly of polymersomes through the cooperative self-assembly of nanoparticles and amphiphilic polymers. Polymersomes densely packed with magnetic nanoparticles in the polymersome membrane (magneto-polymersome) were fabricated with a series of different sized iron oxide nanoparticles. The distribution of nanoparticles in a polymersome membrane was size-dependent; while small nanoparticles were dispersed in a polymer bilayer, large particles formed a well-ordered superstructure at the interface between the inner and outer layer of a bilayer membrane. The yield of magneto-polymersomes increased with increasing the diameter of incorporated nanoparticles. Moreover, the size of the polymersomes was effectively controlled by varying the size of incorporated nanoparticles. This size-dependent self-assembly was attributed to the polymer chain entropy effect and the size-dependent localization of nanoparticles in polymersome bilayers. The transverse relaxation rates (r2) of magneto-polymersomes increased with increasing the nanoparticle diameter and decreasing the size of polymersomes, reaching 555 ± 24 s(-1) mM(-1) for 241 ± 16 nm polymersomes, which is the highest value reported to date for superparamagnetic iron oxide nanoparticles.

Abstract
Polymersome vesicles and wormlike filomicelles self-assembled with amphiphilic, degradable block copolymers have recently shown promise in application to cancer therapy. In the case of filomicelles, dense, hydrophilic brushes of poly(ethylene glycol) on these nanoparticles combine with flexibility to nonspecifically delay clearance by phagocytes in vivo, which has motivated the development of "self" peptides that inhibit nanoparticle clearance through specific interactions. Delayed clearance, as well as robustness of polymer assemblies, opens the dosage window for delivery of increased drug loads in the polymer assemblies and increased tumor accumulation of drug(s). Antibody-targeting and combination therapies, such as with radiotherapy, are emerging in preclinical animal models of cancer. Such efforts are expected to combine with further advances in polymer composition, structure, and protein/peptide functionalization to further enhance transport through the circulation and permeation into disease sites.

Abstract
In this study, three types of hybrid nanotubes (NTs), ie, oxidized multiwalled carbon NTs (COOH MWCNTs), heparin (Hep)-conjugated MWCNTs (Hep MWCNTs), and diblock copolymer polyglycolic acid (PGA)-co-heparin conjugated to MWCNTs (PGA MWCNTs), were synthesized with improved biocompatibility and drug-loading capacity. Hydrophilic Hep substituents on MWCNTs improved biocompatibility and acted as nucleus-sensitive segments on the CNT carrier, whereas the addition of PGA enhanced drug-loading capacity. In the PGA MWCNT system, the amphiphilic copolymer (PGA-Hep) formed micelles on the side walls of CNTs, as confirmed by electron microscopy. The PGA system encapsulated the hydrophobic drug with high efficiency compared to the COOH MWCNT and Hep MWCNT systems. This is because the drug was loaded onto the PGA MWCNTs through hydrophobic forces and onto the CNTs by π-π stacking interactions. Additionally, most of the current drug-carrier designs that target cancer cells release the drug in the lysosome or cytoplasm. However, nuclear-targeted drug release is expected to kill cancer cells more directly and efficiently. In our study, PGA MWCNT carriers effectively delivered the active anticancer drug doxorubicin into targeted nuclei. This study may provide an effective strategy for the development of carbon-based drug carriers for nuclear-targeted drug delivery.

Abstract
Self-assembled systems from biodegradable amphiphilic polymers at the nanometer scale, such as nanotubes, nanoparticles, polymer micelles, nanogels, and polymersomes, have attracted much attention especially in biomedical fields. Among these nano-aggregates, polymersomes have attracted tremendous interests as versatile carriers due to their colloidal stability, tunable membrane properties and ability of encapsulating or integrating a broad range of drugs and molecules. Biodegradable block polymers, especially aliphatic polyesters such as polylactide, polyglycolide and poly (ε-caprolactone) have been widely used as biomedical materials for a long time to well fit the requirement of biomedical drug carriers. To have a precise control of the aggregation behavior of nano-aggregates, the more ordered polypeptide has been used to self-assemble into the drug carriers. In this review we focus on the study of polymersomes which also named pepsomes formed by polypeptide-based copolymers and attempt to clarify the polypeptide-based polymersomes from following aspects: synthesis and characterization of the polypeptide-based copolymers, preparation, multifunction and application of polypeptide-based polymersomes.

Abstract
Metallic nanoparticles (MNPs) such as iron oxide and gold nanoparticles are interesting platforms to build theragnostic nanocarriers which combine both therapeutic and diagnostic functions within a single nanostructure. Nevertheless, their surface must be functionalized to be suitable for in vivo applications. Surface functionalization also provides binding sites for targeting ligands, and for drug loading. This review focuses on the materials and surface chemistry used to build hybrid nanocarriers that are inorganic cores functionalized with organic materials. The surface state of the MNPs largely depends on their synthesis routes, and dictates the strategies used for functionalization. Two main strategies can be found in the literature: the design of core-shell nanosystems, or embedding nanoparticles in organic materials. Emerging tendencies such as the use of clusters or alternative coating materials are also described. To present both hydrophilic and lipophilic nanosystems, we chose the doxorubicin anticancer agent as an example, as the molecule presents an affinity for both types of materials.

Abstract
This present article demonstrates the strategy to prepare photoresponsive reduced graphene oxide with mussel inspired adhesive material dopamine (DN) and photochromic dye spiropyran (SP) conjugated to the backbone of the targeting ligand hyaluronic acid (HA; HA-SP). Graphene oxide (GO) was reduced by prepared HA-SP accepting the advantages of catechol chemistry under mildly alkaline condition enabling to achieve functionalized graphene (rGO/HA-SP) as fluorescent nanoparticles. Due to containing HA, rGO/HA-SP can bind to the CD44 cell receptors. The prepared rGO/HA-SP is able to retain its photochromic features and can be converted to merocyanine (MC) form upon irradiation with UV light (wavelength: 365 nm) displaying purple color. Photochromic behavior of rGO/HA-SP was monitored by UV-vis and fluorescence spectroscopy. In vitro fluorescence behavior, examined by confocal laser scanning microscope (CLSM), of rGO/HA-SP in cancerous A549 cell lines assured that efficient delivery of rGO/HA-SP was gained due to HA as targeting ligand. In this work, we have shown that in vivo fluorescence image of spiropyran is possible by administrating MC form solution of rGO/HA-SP using Balb/C mice as in vivo modal. Accumulation of rGO/HA-SP in tumor tissue from biodistribution analysis strongly supports the specific delivery of prepared graphene to the target destination. The well tuned drug release manner from the surface of rGO/HA-SP strongly recommends the developed material not only as fluorescent probe for diagnosis but also as a drug carrier in drug delivery system.

Abstract
An efficient tumor-targeted niosomal delivery system for the vehiculation of doxorubicin hydrochloride as an anticancer agent was designed. Niosomes were prepared from a mixture of an opportunely modified Pluronic L64 surfactant and cholesterol as a membrane additive and characterized in terms of size and related distribution function and drug entrapment efficiency. After the preparation, transferrin was conjugated to niosomes to produce transferrin (Tf) niosomes, and the cytotoxicity of the final formulation was studied. The specific uptake of Tf niosomes into cells was evaluated via incubation of MCF-7 and MDA-MB-231 cells with fluorescently rhodamine-loaded Tf niosomes for various times and concentration intervals and further investigated by fluorescence microscopy. Results showed that doxorubicin can be easily encapsulated into niosomes, which are regular and spherical in shape. Moreover, transferrin conjugate niosomes demonstrated far greater extents of cellular uptake by MCF-7 and MDA-MB-231 cells, suggesting that they were mainly taken up by transferrin receptor-mediated endocytosis. Doxorubicin-loaded niosome anticancer activity was also achieved against MCF-7 and MDA-MB-231 tumor cell lines, and a significant reduction in viability in a dose- and time-related manner was observed. Finally, our formulation could be potentially useful as a target doxorubicin delivery system in anticancer therapy.

Abstract
Rapid and efficient side-chain functionalization of polypeptide with neighboring carboxylgroups is achieved via the combination of ring-opening polymerization and subsequent thiol-yne click chemistry. The spontaneous formation of polymersomes with uniform size is found to occur in aqueous medium via electrostatic interaction between the anionic polypeptide and cationic doxorubicin hydrochloride (DOX·HCl). The polymersomes are taken up by A549 cells via endocytosis, with a slightly lower cytotoxicity compared with free DOX ·HCl. Moreover, the drug-loaded polymersomes exhibit the enhanced therapeutic efficacy, increase apoptosis in tumor tissues, and reduce systemic toxicity in nude mice bearing A549 lung cancer xenograft, in comparison with free DOX ·HCl.

Abstract
The pH and reduction dual-responsive polypeptide nanogels with self-reinforced endocytoses were prepared through ring-opening polymerization of l-glutamate N-carboxyanhydrides, deprotection of benzyl group and subsequent quaternization reaction between γ-2-chloroethyl-l-glutamate unit in polypeptide block and 2,2'-dithiobis(N,N-dimethylethylamine). The nanogels were revealed to exhibit smart pH and reduction dual-responsiveness, and excellent biocompatibilities, which expressed great potential as antitumor drug nanocarriers. Doxorubicin (DOX) as a model antitumor drug was loaded into nanogels through dispersion. DOX-loaded nanogels displayed a stable core-cross-linked structure under normal physiological condition (pH7.4), while rapidly releasing the payloads in the mimicking endosomal (pH5.3), tumor tissular (pH6.8) or intracellular reductive microenvironments (10.0mM glutathione). Confocal fluorescence microscopy demonstrated that DOX-loaded nanogels could deliver DOX into HepG2 cells (a human hepatoma cell line) more efficiently than the parent DOX-loaded micelle and free DOX. The enhanced cellular internalizations of DOX-loaded nanogels were more significant under tumor tissular acidic condition (pH6.8) ascribed to the quaternary ammonium groups in the cores. In addition, DOX-loaded nanogels exhibited improved in vitro and in vivo antitumor activities, and in vivo securities compared with DOX-loaded micelle and free DOX. These excellent features of the smart nanogels with quaternary ammonium groups were endowed with a bright prospect for intracellular targeting antitumor drug delivery.

Abstract
Doxorubicin hydrochloride (DOX) is an effective anticancer agent for leukemia chemotherapy, although its clinical use has been limited because of its side effects such as cardiotoxicity, alopecia, vomiting, and leucopenia. Attention has been focussed on developing new drug carriers with high adsorption capacity and rapid adsorption rate in order to minimize the side effects of DOX. Graphene oxide (GO), a new type of nanomaterial in the carbon family, was prepared by Hummers method and used as adsorbent for DOX from aqueous solution. The physico-chemical properties of GO were characterized by transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), zeta potential, and element analysis. The adsorption properties of DOX on GO were studied as a function of contact time, adsorbent dosage, temperature and pH value. The results showed that GO had a maximum adsorption capacity of 1428.57 mg/g and the adsorption isotherm data fitted the Langmuir model. The kinetics of adsorption fits a pseudo-second-order model. The thermodynamic studies indicate that the adsorption of DOX on GO is spontaneous and endothermic in nature.

Abstract
A series of dual stimuli responsive synthetic polymer bioconjugate chimeric materials, poly(N-isopropylacrylamide)55-block-poly(L-histidine)n [p(NIPAM)55-b-p(His)n] (n=50, 75, 100, 125), have been synthesized by employing reversible addition-fragmentation chain transfer polymerization of NIPAM, followed by ring-opening polymerization of α-amino acid N-carboxyanhydrides. The dual stimuli responsive properties of the resulting biocompatiable and membrenolytic p(NIPAM)55-b-p(His)n polymers are investigated for their use as a stimuli responsive drug carrier for tumor targeting. Highly uniform self-assembled micelles (∼55 nm) fabricated by p(NIPAM)55-b-p(His)n polymers display sharp thermal and pH responses in aqueous media. An anticancer drug, doxorubicin (Dox), is effectively encapsulated in the micelles and the controlled Dox release is investigated in different temperature and pH conditions. Antitumor effect of the released Dox is also assessed using the HepG2 human hepatocellular carcinoma cell lines. Dox molecules released from the [p(NIPAM)55-b-p(His)n] micelles remain biologically active and have stimuli responsive capability to kill cancer cells. The self-assembling ability of these hybrid materials into uniform micelles and their efficiency to encapsulate Dox makes them a promising drug carrier to cancer cells. The new chimeric materials thus display tunable properties that can make them useful for a molecular switching device and controlled drug delivery applications needing responses to temperature and pH for the improvement of cancer chemotherapy.

Abstract
A series of well-defined thermoresponsive diblock copolymers (PEO45-b-PtNEAn, n=22, 44, 63, 91, 172) were prepared by the atom transfer radical polymerization of trans-N-(2-ethoxy-1,3-dioxan-5-yl) acrylamide (tNEA) using a poly(ethylene oxide) (PEO45) macroinitiator. All copolymers are water-soluble at low temperature, but upon quickly heating to 37 °C, laser light scattering (LLS) and transmission electron microscopy (TEM) characterizations indicate that these copolymers self-assemble into aggregates with different morphologies depending on the chain length of PtNEA and the polymer concentration; the morphologies gradually evolved from spherical solid nanoparticles to a polymersome as the degree of polymerization ("n") of PtNEA block increased from 22 to 172, with the formation of clusters with rod-like structure at the intermediate PtNEA length. Both the spherical nanoparticle and the polymersome are stable at physiological pH but susceptible to the mildly acidic medium. Acid-triggered hydrolysis behaviors of the aggregates were investigated by LLS, Nile red fluorescence, TEM, and (1)H NMR spectroscopy. The results revealed that the spherical nanoparticles formed from PEO45-b-PtNEA44 dissociated faster than the polymersomes of PEO45-b-PtNEA172, and both aggregates showed an enhanced hydrolysis under acidic conditions. Both the spherical nanoparticle and polymersome are able to efficiently load the hydrophobic doxorubicin (DOX), and water-soluble fluorescein isothiocyanate-lysozyme (FITC-Lys) can be conveniently encapsulated into the polymersome without using any organic solvent. Moreover, FITC-Lys and DOX could be coloaded in the polymersome. The drugs loaded either in the polymersome or in the spherical nanoparticle could be released by acid triggering. Finally, the DOX-loaded assemblies display concentration-dependent cytotoxicity to HepG2 cells, while the copolymers themselves are nontoxic.

Abstract
Nonsmall cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. Herein, we develop a polypeptide-based block ionomer complex formed by anionic methoxy poly(ethylene glycol)-b-poly(L-glutamic acid) (mPEG-b-PLG) and cationic anticancer drug doxorubicin hydrochloride (DOX·HCl) for NSCLC treatment. This complex spontaneously self-assembled into spherical nanoparticles (NPs) in aqueous solutions via electrostatic interaction and hydrophobic stack, with a high loading efficiency (almost 100%) and negative surface charge. DOX·HCl release from the drug-loaded micellar nanoparticles (mPEG-b-PLG-DOX·HCl) was slow at physiological pH, but obviously increased at the acidic pH mimicking the endosomal/lysosomal environment. In vitro cytotoxicity and hemolysis assays demonstrated that the block copolypeptide was cytocompatible and hemocompatible, and the presence of copolypeptide carrier could reduce the hemolysis ratio of DOX·HCl significantly. Cellular uptake and cytotoxicity studies suggested that mPEG-b-PLG-DOX·HCl was taken up by A549 cells via endocytosis, with a slightly slower cellular internalization and lower cytotoxicity compared with free DOX·HCl. The pharmacokinetics study in rats showed that DOX·HCl-loaded micellar NPs significantly prolonged the blood circulation time. Moreover, mPEG-b-PLG-DOX·HCl exhibited enhanced therapeutic efficacy, increased apoptosis in tumor tissues, and reduced systemic toxicity in nude mice bearing A549 lung cancer xenograft compared with free DOX·HCl, which were further confirmed by histological and immunohistochemical analyses. The results demonstrated that mPEG-b-PLG was a promising vector to deliver DOX·HCl into tumors and achieve improved pharmacokinetics, biodistribution and efficacy of DOX·HCl with reduced toxicity. These features strongly supported the interest of developing mPEG-b-PLG-DOX·HCl as a valid therapeutic modality in the therapy of human NSCLC and other solid tumors.

Abstract
Local and temporal control of drug release has for long been a main focus in the development of novel drug carriers. Polymersomes, which can load both hydrophilic and hydrophobic species and, at the same time, be tailored to respond to a desired stimulus, have drawn much attention over the last decade. Here we describe polymersomes able to encapsulate up to 6% (w/w) of doxorubicin (DOX) together with 30% (w/w) of superparamagnetic iron oxide nanoparticles (USPIO; γ-Fe2O3). Upon internalization in HeLa cells and when a high frequency AC magnetic field (14mT at 750kHz) was applied, the developed delivery system elicited an 18% increase in cell toxicity, associated with augmented DOX release kinetics. In order to ensure that the observed cytotoxicity arose from the increased doxorubicin release and not from a pure magnetic hyperthermia effect, polymersomes loaded with magnetic nanoparticles alone were also tested. In this case, no increased toxicity was observed. We hypothesize that the magnetic field is inducing a very local hyperthermia effect at the level of the polymersome membrane, increasing drug release. This approach opens new perspectives in the development of smart delivery systems able to release drug upon demand and therefore, improving treatment control.

Efficacious hepatoma-targeted nanomedicine self-assembled from galactopeptide and doxorubicin driven by two-stage physical interactions. J Control Release 2012; 169:193-203.

Abstract
Polymers bearing pendant galactosyl group are attractive for targeted intracellular antitumor drug delivery to hepatoma cells (e.g. HepG2 and SMMC7721 cells) with asialoglycoprotein receptor (ASGP-R). Herein, a series of galactopeptides was synthesized through ring-opening polymerization of L-glutamate N-carboxyanhydride, deprotection of benzyl group and subsequent Huisgens cycloaddition "click" reaction with azide-modified galactosyl group. The copolypeptides were revealed to have excellent hemocompatibilities, and cell and tissue compatibilities, which rendered their potential for drug delivery applications. The hepatoma-targeted micellar nanoparticle (i.e. nanomedicine) was fabricated by cooperative self-assembly of galactopeptide and doxorubicin (DOX) induced by two-stage physical interactions. In vitro DOX release from nanomedicine was accelerated in the intracellular acidic condition. Through the recognition between galactose ligand and ASGP-R of HepG2 cells, the endocytosis of galactosylated nanomedicine was significantly promoted, which was demonstrated by confocal laser scanning microscopy and flow cytometry. Remarkably, the galactose-decorated nanomedicine retained much higher antitumor activity toward HepG2 cells in contrast to the nanomedicine without galactosyl group in vitro and in vivo. The above superiorities indicated that the galactosylated nanomedicine possessed great promising for hepatoma-targeted chemotherapy.

Abstract
Nanoparticle-based drug delivery systems have been developed to improve the efficacy and reduce the systemic toxicity of a wide range of drugs. Although clinically approved nanoparticles have consistently shown value in reducing drug toxicity, their use has not always translated into improved clinical outcomes. This has led to the development of "multifunctional" nanoparticles, where additional capabilities like targeting and image contrast enhancement are added to the nanoparticles. However, additional functionality means additional synthetic steps and costs, more convoluted behavior and effects in vivo, and also greater regulatory hurdles. The trade-off between additional functionality and complexity is the subject of ongoing debate and the focus of this Review.

Abstract
We report the development of bioconjugated plasmonic vesicles assembled from SERS-encoded amphiphilic gold nanoparticles for cancer-targeted drug delivery. This new type of plasmonic assemblies with a hollow cavity can play multifunctional roles as delivery carriers for anticancer drugs and SERS-active plasmonic imaging probes to specifically label targeted cancer cells and monitor intracellular drug delivery. We have shown that the pH-responsive disassembly of the plasmonic vesicle, stimulated by the hydrophobic-to-hydrophilic transition of the hydrophobic brushes in acidic intracellular compartments, allows for triggered intracellular drug release. Because self-assembled plasmonic vesicles exhibit significantly different plasmonic properties and greatly enhanced SERS intensity in comparison with single gold nanoparticles due to strong interparticle plasmonic coupling, disassembly of the vesicles in endocytic compartments leads to dramatic changes in scattering properties and SERS signals, which can serve as independent feedback mechanisms to signal cargo release from the vesicles. The unique structural and optical properties of the plasmonic vesicle have made it a promising platform for targeted combination therapy and theranostic applications by taking advantage of recent advances in gold nanostructure based in vivo bioimaging and photothermal therapy and their loading capacity for both hydrophilic (nucleic acids and proteins) and hydrophobic (small molecules) therapeutic agents.

Abstract
Titratable polyanions, and more particularly polymers bearing carboxylate groups, have been used in recent years to produce a variety of pH-sensitive colloids. These polymers undergo a coil-to-globule conformational change upon a variation in pH of the surrounding environment. This conformational change can be exploited to trigger the release of a drug from a drug delivery system in a pH-dependent fashion. This review describes the current status of pH-sensitive vesicles, polymeric micelles, and nanospheres prepared with polycarboxylates and their performance as nano-scale drug delivery systems, with emphasis on our recent contribution to this field.
