Immunotherapy has emerged as a potent strategy in cancer treatment, with many approved drugs and modalities in the development stages. Despite its promise, immunotherapy is not without its limitations, including side effects and suboptimal efficacy. Using nanoparticles (NPs) as delivery vehicles to target immunotherapy to lymph nodes (LNs) can improve the efficacy of immunotherapy drugs and reduce...
The occurrence of osteoarthritis (OA) is highly associated with the inflammatory hypoxic microenvironment. Yet currently no attention has been paid to fabricating hypoxia‐responsive platforms for OA treatment. Herein, an injectable hydrogel microsphere system (HAM‐SA@HCQ) focusing on the hypoxic inflamed joint is prepared with methacrylate‐modified sulfonated azocalix[4]arene (SAC4A‐MA), methacrylated...
Perovskite oxides exhibit bifunctional activity for both oxygen reduction (ORR) and oxygen evolution reactions (OER), making them prime candidates for energy conversion in applications like fuel cells and metal‐air batteries. Their intrinsic catalytic prowess, combined with low‐cost, abundance, and diversity, positions them as compelling alternatives to noble metal and metal oxides catalysts. This...
Developing desirable sensors is crucial for underwater perceptions and operations. The perceiving organs of marine creatures have greatly evolved to react accurately and promptly underwater. Inspired by the fish lateral line, this study proposes a triboelectric dynamic pressure sensor for underwater perception. The biomimetic lateral line sensor (BLLS) has high sensitivity to the disturbance amplitude/frequency,...
Electrical bioadhesive interface (EBI), especially conducting polymer hydrogel (CPH)‐based EBI, exhibits promising potential applications in various fields, including biomedical devices, neural interfaces, and wearable devices. However, current fabrication techniques of CPH‐based EBI mostly focus on conventional methods such as direct casting, injection, and molding, which remains a lingering challenge...
Conjugated polymer has the potential to be applied on flexible devices as an active layer, but further investigation is still hindered by poor conductivity and mechanical stability. Here, this work demonstrates a dopant‐enhanced conductive polymer thin film and its application in dimethyl methylphosphonate (DMMP) sensor.

Lithium–sulfur (Li–S) batteries, which store energy through reversible redox reactions with multiple electron transfers, are seen as one of the promising energy storage systems of the future due to their outstanding advantages. However, the shuttle effect, volume expansion, low conductivity of sulfur cathodes, and uncontrollable dendrite phenomenon of the lithium anodes have hindered the further application...
The power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs) are significantly reduced by defect‐induced charge non‐radiative recombination. Also, unexpected residual strain in perovskite films leads to an unfavorable impact on the stability and efficiency of PSCs, notably flexible PSCs (f‐PSCs). Considering these problems, a thorough and effective strategy is proposed by incorporating...
Cellulose‐based triboelectric nanogenerators (TENGs) have attracted widespread attention due to the low cost and environmentally friendly characteristics of cellulose.
