Abstract
In recent years, the exploration of tumor microenvironment has provided a new approach for tumor treatment. More and more researches are devoted to designing tumor microenvironment-responsive nanogels loaded with therapeutic drugs. Compared with other drug carriers, nanogel has shown great potential in improving the effect of chemotherapy, which is attributed to its stable size, superior hydrophilicity, excellent biocompatibility, and responsiveness to specific environment. This review primarily summarizes the common preparation techniques of nanogels (such as free radical polymerization, covalent cross-linking, and physical self-assembly) and loading ways of drug in nanogels (including physical encapsulation and chemical coupling) as well as the controlled drug release behaviors. Furthermore, the difficulties and prospects of nanogels as drug carriers are also briefly described.

Abstract
Despite recent advances in controlling ice formation and growth, it remains a challenge to design anti-icing materials in various fields from atmospheric to biological cryopreservation. Herein, tungsten diselenide (WSe2)-polyvinyl pyrrolidone (PVP) nanoparticles (NPs) are synthesized through one-step solvothermal route. The WSe2-PVP NPs show synergetic ice regulation ability both in the freezing and thawing processes. Molecularly speaking, PVP containing amides group can form hydrogen bonds with water molecules. At a macro level, the WSe2-PVP NPs show adsorption-inhibition and photothermal conversation effects to synergistically restrict ice growth. Meanwhile, WSe2-PVP NPs are for the first time used for the cryopreservation of human umbilical vein endothelial cell (HUVEC)-laden constructs based on rapid freezing with low concentrations of cryoprotectants (CPAs), the experimental results indicate that a minimal concentration (0.5 mg mL-1) of WSe2-PVP NPs can increase the viabilities of HUVECs in the constructs post cryopreservation (from 55.8% to 83.4%) and the cryopreserved constructs can also keep good condition in vivo within 7 days. Therefore, this work provides a novel strategy to synergistically suppress the formation and growth of the ice crystalsfor the cryopreservation of cells, tissues, or organs.

Abstract
Radiotherapy (RT) in practical use often suffers from off-target side effects and ineffectiveness against hypoxic tumor microenvironment (TME) as well as remote metastases. With regard to these problems, herein, we provide semiconductor heterojunction structured WO2.9-WSe2-PEG nanoparticles to realize a synergistic RT/photothermal therapy (PTT)/checkpoint blockade immunotherapy (CBT) for enhanced antitumor and antimetastatic effect. Based on the heterojunction structured nanoparticle with high Z element, the nanosystem could realize non-oxygen-dependent reactive oxygen species generation by catalyzing highly expressed H2O2 in TME upon X-ray irradiation, which could further induce immunogenic cell death. Meanwhile, this nanosystem could also induce hyperthermia upon near-infrared irradiation to enhance RT outcome. With the addition of anti-PD-L1 antibody-based CBT, our results give potent evidence that local RT/PTT upon mild temperature and low radiation dose could efficiently ablate local tumors and inhibit tumor metastasis as well as prevent tumor rechallenge. Our study provides not only one kind of radiosensitizer based on semiconductor nanoparticles but also a versatile nanoplatform for simultaneous triple-combined therapy (RT/PTT/CBT) for treating both local and metastasis tumors.
