This review highlights how natural polysaccharide-based microneedles (PMNs) are emerging as a transformative platform for cancer immunotherapy. We report their unique dual role in drug delivery and immune regulation, the innovative use of 3D printing for precision fabrication, and their smart responsiveness to the tumor environment. By integrating biocompatibility, enhanced drug loading, and controlled release, polysaccharide-based microneedles (PMNs) offer a promising strategy to overcome challenges in traditional cancer immunotherapies, potentially supporting the development of more effective and personalized treatments.

Scientists have developed a novel Cr-based single-atom catalyst that enables highly efficient hydrogen peroxide (H₂O₂) production in acidic environments through an electrochemical process. This breakthrough, guided by molecular dynamics simulations, reveals a self-adjusting mechanism with the catalyst actively restructuring during the reaction, achieving exceptional selectivity that rivals or even surpasses that of conventional Co-based catalysts.

Recently, a research team led by Academician Lijun Wang at CIOMP under UCAS has systematically reviewed the latest advancements in transfer printing (TP) technology. The team detailed its practical applications in integrating III-V semiconductor devices into photonic integrated circuits (PIC), demonstrating its significant potential for developing high-performance, high-reliability PICs. Their work provides crucial theoretical guidance for improving transfer yield and precision, while also offering forward-looking insights into current technical challenges and future development directions for this technology.

 A methodology to enhance the energy density of supercapacitors based on a V₄C₃T_Z MXene has been developed via enhancement of the operating electrochemical window using a 17.5 molal LiBr/H₂O highly concentrated electrolyte.

An electrode for structural batteries was developed by combining carbon nanotubes (CNT) with quartz woven fabric (QWF), demonstrating the potential for structural batteries applicable to the aerospace and defense industries.

Despite the long-standing reputation of each, as well as distinct underlying physics, laser speckle contrast imaging (LSCI) and imaging photoplethysmography (IPPG) reach concordance on functional cerebral haemodynamics. The unified, heartbeat-resolved, camera-based readout offers fast, wide-field assessment of cortical perfusion for the operating theatre.
