Mesoporous silica nanoparticles (MSNs) have been widely praised as nanoadjuvants in vaccine/tumor immunotherapy thanks to their excellent biocompatibility, easy‐to‐modify surface, adjustable particle size, and remarkable immuno‐enhancing activity. However, the application of MSNs is still greatly limited by some severe challenges including the unclear and complicated relationships of structure and...
Ion‐interference therapy (IIT) utilizes ions to disturb intracellular biological processes and has been received increasing attention in tumor treatments recently. However, the low therapeutic efficiency still hinders its further biological applications. Herein, via a simple and one‐pot gas diffusion process, polyethylene glycol (PEG)‐modified Mn2+ ions and usnic acid (UA)‐incorporated CaCO3 nanomaterials...
Single‐component white light emitters based on the all‐inorganic perovskites will act as outstanding candidates for applications in solid‐state lighting thanks to their abundant energy states for self‐trapped excitons (STE) with ultra‐high photoluminescence (PL) efficiency. Here, a complementary white light is realized by dual STEs emissions with blue and yellow colors in a single‐component perovskite...
Nowadays, Fenton chemistry‐based chemodynamic therapy (CDT) is an emerging approach to killing tumor cells by converting endogenous H2O2 into cytotoxic hydroxyl radicals (·OH). However, the elimination of ·OH by intracellular overexpressed glutathione (GSH) results in unsatisfactory antitumor efficiency. In addition, the single mode of consuming GSH and undesirable drug loading efficiency cannot guarantee...
Sonodynamic therapy (SDT) has considerably revolutionized the healthcare sector as a viable noninvasive therapeutic procedure. It employs a combination of low‐intensity ultrasound and chemical entities, known as a sonosensitizer, to produce cytotoxic reactive oxygen species (ROS) for cancer and antimicrobial therapies. With nanotechnology, several unique nanoplatforms are introduced as a sonosensitizers,...
The outcome of laser‐triggered plasmons‐induced phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is significantly limited by the hypoxic tumor microenvironment and the upregulation of heat shock proteins (HSPs) in response to heat stress. Mitochondria, the biological battery of cells, can serve as an important breakthrough to overcome these obstacles. Herein, dendritic...
The efficiency of reactive oxygen species (ROS)‐mediated cancer therapy is restrained by intrinsic characteristics in the tumor microenvironment (TME), such as overexpressed glutathione (GSH), hypoxia and limited efficiency of H2O2. In this work, intelligent copper‐dropped calcium carbonate loading sonosensitizer Ce6 nanoparticles (Cu/CaCO3@Ce6, CCC NPs) are established to realize TME‐responsive self‐supply...
In spite of the widespread application of vaccine adjuvants in various preventive vaccines at present, the existing adjuvants are still hindered by weak cellular immunity responses in therapeutic cancer vaccines. Herein, a hollow silica nanoadjuvant containing aluminum hydroxide spikes on the surface (SiAl) is synthesized for the co‐loading of chemotherapeutic drug doxorubicin (Dox) and tumor fragment...
Carbonized Polymer Dots
In article number 2106863, Yeqing Chen, Ping Liang, Jun Lin, and co‐workers synthesize transition metal Mn ions doped in the form of covalent Mn–O bonds. The Mn–O bridge accelerates the electron flow between adjacent sp2 domains and enhances the electron transport in the Mn–carbonized polymer dots, thus improving the photoluminescence quantum yield and catalytic performance...
Carbonized polymer dots (CPDs) have received tremendous attention during the last decade due to their excellent fluorescent properties and catalytic performance. Doping CPDs with transition metal atoms accelerates the local electron flow in CPDs and improves the fluorescent properties and catalytic performance of the CPDs. However, the binding sites and the formation mechanisms of the transition‐metal‐atom‐doped...
Of all the reaction oxygen species (ROS) therapeutic strategies, NIR light‐induced photocatalytic therapy (PCT) based on semiconductor nanomaterials has attracted increasing attention. However, the photocatalysts suffer from rapid recombination of electron‐hole pairs due to the narrow band gaps, which are greatly restricted in PCT application. Herein, Bi2Se3/Au heterostructured photocatalysts are...
In order to achieve better antitumor therapeutic efficacy and inhibit tumor metastasis, a multifunctional nanovaccine based on L‐arginine (LA)‐loaded black mesoporous titania (BMT) is fabricated. In this system, LA is utilized as the exogenous NO supplementation for gas therapy, and BMT is served as acoustic sensitizer for sonodynamic therapy. The ultrasound (US) as the exogenous stimulus can simultaneously...
Multimodal synergistic therapy based on photodynamic therapy (PDT), photothermal therapy (PTT), and chemodynamic therapy (CDT) has attracted increasing attention in cancer therapy. However, the scant therapeutic efficiency is always a barrier for further application.

Photoimmunotherapy can not only effectively ablate the primary tumor but also trigger strong antitumor immune responses against metastatic tumors by inducing immunogenic cell death. Herein, Cu2MoS4 (CMS)/Au heterostructures are constructed by depositing plasmonic Au nanoparticles onto CMS nanosheets, which exhibit enhanced absorption in near‐infrared (NIR) region due to the newly formed mid‐gap state...
Glucose oxidase (GOx) can react with intracellular glucose and oxygen (O2) to produce hydrogen peroxide (H2O2) and gluconic acid, which can cut off the nutrition source of cancer cells and consequently inhibit their proliferation. Therefore, GOx is recognised as an ideal endogenous oxido‐reductase for cancer starvation therapy. This process can further regulate the tumor microenvironment by increasing...
Combining luminescent transition metal complex with super‐resolution microscopy is an excellent strategy for the long‐term visualization of the dynamics of subcellular structures in living cells.
