| 1 | Theranostic nanoparticles with tumor-specific enzyme-triggered size reduction and drug release to perform photothermal therapy for breast cancer treatment显示文摘Although progress has been indeed made by nanomedicines, their efficacies for cancer treatment remain low, consequently leading to failures in translation to clinic. To improve the drug delivery efficiency,nanoparticles need to change size so as to fully utilize the enhanced permeability and retention(EPR) effect of solid tumor, which is the golden principle of nanoparticles used for cancer treatment. Herein, we employed cationic small-sized red emission bovine serum albumin(BSA) protected gold nanocluster(Au NC@CBSA,21.06 nm) to both load indocyanine green(ICG) and act as imaging probe to realize theranostic. Then Au NC@CBSA-ICG was fabricated with negatively charged hyaluronic acid(HA) to form Au NC@CBSAICG@HA, which was about 200 nm to easily retain at tumor site and could be degraded by tumor-specific hyaluronidase into small nanoparticles for deep tumor penetration. The HA shell also endowed Au NC@CBSA-ICG@HA with actively targeting ability and hyaluronidase-dependent drug release. Furthermore, the quenching and recovery of fluorescence revealed the interaction between ICG and carrier, which was essential for the investigation of pharmacokinetic profiles. No matter in vitro or in vivo, Au NC@CBSAICG@HA showed markedly anti-tumor effect, and could suppress 95.0% of tumor growth on mice breast cancer model. All results demonstrated Au NC@CBSA-ICG@HA was potential for breast cancer therapy. | Rui Liu Chuan Hu Yuanyuan Yang Jingqing Zhang Huile Gao | 2019 | Acta Pharmaceutica Sinica B2019，9，2： | 24 |

| 3 | One-pot photoreduction to prepare NIR-absorbing plasmonic gold nanoparticles tethered by amphiphilic polypeptide copolymer for synergistic photothermal-chemotherapy显示文摘We developed one-pot photoreduction strategy to prepare near infrared light(NIR)-absorbing plasmonic gold nanoparticles(Au NPs) tethered by amphiphilic polypeptide copolymer poly(L-cysteine)-b-poly(ethylene oxide)(PLC-b-PEO). The PLC-b-PEO@Au NPs possessed strong NIR absorption at 700–1100 nm and ultrahigh photothermal conversion efficiency of 62.1%. Upon the NIR irradiation(808nm,2 W/cm^2,5 min), the PLC-b-PEO@Au NPs(1mg/mL) sharply attained an elevation of 30.8℃ and the hyperthermia effect could efficiently kill cancer cells in vitro. As for the PT-CT treatment, the doxorubicin(DOX)-loaded nanoparticles of DOX-PLC-b-PEO@Au NPs gave a combination index of 0.9 compared to single chemotherapy(CT) or photothermal therapy(PT), demonstrating a synergistic effect. | Siqi Yang Linzhu Zhou Yue Su Rong Zhang Chang-Ming Dong | 2019 | Chinese Chemical Letters2019，30，1： | 6 |
| 4 | Comprehensive Application of Graphene: Emphasis on Biomedical Concerns显示文摘Graphene, sp^2 hybridized carbon framework of one atom thickness, is reputed as the strongest material to date. It has marked its impact in manifold applications including electronics, sensors, composites, and catalysis. Current state-of-the-art graphene research revolves around its biomedical applications. The two-dimensional(2D) planar structure of graphene provides a large surface area for loading drugs/biomolecules and the possibility of conjugating fluorescent dyes for bioimaging. The high near-infrared absorbance makes graphene ideal for photothermal therapy. Henceforth, graphene turns out to be a reliable multifunctional material for use in diagnosis and treatment. It exhibits antibacterial property by directly interacting with the cell membrane. Potential application of graphene as a sca old for the attachment and proliferation of stem cells and neuronal cells is captivating in a tissue regeneration scenario. Fabrication of 2D graphene into a 3D structure is made possible with the help of 3D printing, a revolutionary technology having promising applications in tissue and organ engineering. However, apart from its advantageous application scope, use of graphene raises toxicity concerns. Several reports have confirmed the potential toxicity of graphene and its derivatives, and the inconsistency may be due to the lack of standardized consensus protocols. The present review focuses on the hidden facts of graphene and its biomedical application, with special emphasis on drug delivery, biosensing, bioimaging, antibacterial, tissue engineering, and 3D printing applications. | S.Syama P.V.Mohanan | 2019 | Nano-Micro Letters2019，11，1： | 4 |
| 5 | Polydopamine and ammonium bicarbonate coated and doxorubicin loaded hollow cerium oxide nanoparticles for synergistic tumor therapy显示文摘The development of effective nanoplatforms is extremely necessary for cancer therapy.Herein,we prepared polydopamine(PDA)andammonium bicarbonate(NH4HCO3)coated and doxorubicin(Dox)loaded hollow cerium oxide(CeO2)NPs(PDAC NPs),which showedexcellent synergistic effect for photothermal therapy,chemotherapy and chemodynamic therapy.Under near infrared laser irradiation,PDA shell could absorb the incident light and convert it into heat,which could not only kill tumor cells with hyperthermia,but also trigger thedecomposition of NH4HCO3 into gaseous carbon dioxide and ammonia,leading to the destroy of PDA shell.The leakage of PDA furtheraccelerated Dox release and exposed CeO2 surface,in which Dox could enter into cell nucleus to induce chemotherapy,and CeO2 couldcatalyze cellular hydrogen peroxide into hydroxyl radical to present chemodynamic therapy.In fact,PDAC NPs showed an excellenttherapeutic efficacy both in vitro and in vivo.This design provides a new strategy for synergistic tumor therapy. | Keqiang Xu Yan Cheng Jiao Yan Yanlin Feng Runxiao Zheng Xiaqhig Wu Yanjing Wang Panpan Song Haiyuan Zhang | 2019 | Nano Research2019，12，12： | 4 |

In this work, gold nanoprisms (GNPs) was synthesized and then modified with LyP-1, a tumor-homing peptide, to improve the affinity of the GNPs to tumor cells, thus, to improve the efficacy of tumor-targeted photothermal therapy. The introduction of NIR dye IR780 not only enabled the GNPs-based nanosystem with the surface-enhanced resonant Raman scattering (SERRS) property, but also enhanced the plasmonic photothermal property which delivering therapeutic heating by 660 nm laser irradiation. The obtained GNPs/IR780-LyP-1 presented significantly increased of photothermal conversion in vitro and in vivo, which resulted in enhanced tumor-targeting photothermal therapeutic efficacy after laser irradiation. Hence, the GNPs/IR780-LyP-1 prepared in this study can be served as a Raman-encoded molecular imaging candidate and photothermal therapy agents for future cancer treatment. | Xi Huang Yanlong Yin Min Wu Wang Zan Qian Yang | 2019 | Chinese Chemical Letters2019，30，6： | 3 |

| 8 | Shape-controlled synthesis of liquid metal nanodroplets for photothermal therapy显示文摘The capping agents for liquid metal (LM) nanodroplets in aqueous solutions are restricted to thiol-containing and positively-charged molecules or macromolecules.However,both thiolate-metal complex and electrostatic interaction are liable to detachment upon strong mechanical forces such as sonication,leading to limited stability and applications.To address this,we utilized ultrasmall water soluble melanin nanoparticles (MNPs) as the capping agent,which exhibited strong metal binding capability with the oxide layer of gallium based LMs and resulted in enhanced stability.Interestingly,shape-controlled synthesis of LM nanodroplets can be achieved by the incorporation of MNPs.Various EGaln nanostructures including nanorice,nanosphere and nanorod were obtained by simply tuning the feed ratio,sonication time,and suspension temperature.Among these shapes,EGaln nanorice has the best photothermal conversion efficiency,which could be leveraged for photothermal therapy. | Junjie Yan Xudong Zhang Yang Liu Yanqi Ye Jicheng Yu Qian Chen Jinqiang Wang Yuqi Zhang Quanyin Hu Yang Kang Min Yang Zhen Gu | 2019 | Nano Research2019，12，6： | 2 |
| 9 | Visual dual chemodynamic/photothermal therapeutic nanoplatform based on superoxide dismutase plus Prussian blue显示文摘Enzyme-based anticancer therapy is more attractive for the less side effect than conventional chemotherapy.However,the poor stability and low membrane permeability of enzymes during the intracellular delivery are constraints for its practical applications.In this work,we synthesized novel near-infrared (NIR)-responsive core-shell-structured Prussian blue@fibrous SiO2 (PBFS) nanoparticles as the carrier of superoxide dismutase (SOD) and a glutathione (GSH)-activated Fenton reagent (DiFe).The PBFS nanoparticles are further modified with aGSH-responsive cationic polymer (poly(2-(acryloyloxy)-N,N-dimethyl-N-(4-(((2-((2-(((4-methyl-2-oxo-2H-chromen-7-yl)carbamoyl)oxy)ethyl)disulfaneyl)ethoxy)carbonyl)amino)benzyl)ethan-1-aminium,PSS) containing disulfide bonds and fluorophores.After SOD and DiFe are loaded on the PBFS-PSS nanoparticles,dual chemodynamic/photothermal therapeutic nanoparticulate systems (PBFS-PSS/DiFe/SOD) are obtained.In vitro experiments show that PBFS-PSS/DiFe/SOD nanoparticles have good biocompatibility and can be tracked under fluorescence microscope during the intracellular delivery process in MCF-7 tumor cells due to the GSH-activated release of fluorophores.They also exhibit high efficiency in NIR photothermal conversion and GSH-activated Fenton reaction in tumor cells,thus achieving high-efficient killing effect of tumor cells based on the combination of photothermal and chemodynamic therapeutic performance (PTT and CDT).This work offers a novel pathway to construct a visual multifunctional nanomedicine platform for future cancer therapy. | Shan Lei Jinxing Chen Kun Zeng Mozhen Wang Xuewu Ge | 2019 | Nano Research2019，12，5： | 2 |
| 10 | Stimuli-responsive nitric oxide generator for light-triggered synergistic cancer photothermal/gas therapy显示文摘As a minimally invasive local cancer therapy,photothermal therapy (PTT) has aroused intensive interests in recent years.However,the therapeutic effect of PTT is still unsatisfying due to the production of heat shock proteins.Combination therapy has been regarded as a promising strategy to enhance therapeutic efficiency.In this study,a novel intelligent protoporphyrin (PplX)-based polymer nanoplatform is developed for synergistic enhancement of cancer treatment through combined PTT and nitric oxide (NO) therapy.The core of the nanoparticle is composed of closely packed porphyrin-based NO donors and PplX branches of the block copolymer.The prepared nanoparticles exhibit good photothermal conversion capability and high sensitivity to release NO under light illumination.And the produced high localized temperature and intracellular NO concentration could efficiently inhibit cancer cells both in vitro and in vivo.More important,this therapeutic nanoplatform can fundamentally eliminate the emergence of multidrug resistance and overcome the hypoxia microenvironment in tumors because of the absence of chemotherapeutic drugs and the oxygen-independent process,thus opening up new ideas for multifunctional therapeutic agent design for treatment of multidrug-resistant cancer. | Xuehui Huang Funeng Xu Huabo Hou Jianwen Hou Yi Wang Shaobing Zhou | 2019 | Nano Research2019，12，6： | 2 |
| 11 | Tumor Photothermal Therapy Employing Photothermal Inorganic Nanoparticles/Polymers Nanocomposites显示文摘The past decade has witnessed the booming developments of the new methodologies for noninvasive tumor treatment, which are considered to overcome the current limitation of low treating efficacy, high risk of tumor recurrence, and severe side effects. Among a variety of novel therapeutic methods, photothermal therapy, employing nanometer-sized agents as the heat generators under near-infrared(NIR) light irradiation to ablate tumors, gives new insights into noninvasive tumor treatments with minimal side effects. Although many nanomaterials possess photothermal effects, inorganic nanoparticles and polymers are the most competitive alternatives considering the high photothermal performance and good biocompatibility. In this review, we summarized the tumor photothermal therapy using the nanocomposites composed of inorganic nanoparticles and polymers. Extinction coefficient and photothermal transduction efficiency are the two main factors to evaluate the photothermal performance of nanocomposites in vitro. Considering the improvement in the stability,biocompatibility, blood circulation half-life, and tumor uptake rate after polymer coating, these nanocomposites should be designed with inorganic core and polymer shell, thus improving the tumor treating efficacy in vivo. Such structure fulfills the requirements of high photothermal performance and good bio-security, making it possible to achieve complete ablation for shallow and small tumors under the safe limitation of NIR laser power density. | Shu-Wei Liu Lu Wang Min Lin Yi Liu Le-Ning Zhang Hao Zhang | 2019 | Chinese Journal of Polymer Science2019，37，2： | 2 |
