Unlocking Long‐Lived Charge‐Separated State in Pentamethine Cyanine Based on Anionic Hofmeister Effect for Photodynamic Immunotherapy

Advanced Science, EarlyView.
Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Unsupervised inter-domain transformation for virtually stained high-resolution mid-infrared photoacoustic microscopy using explainable deep learning

Nature Communications
Mid-infrared photoacoustic microscopy can capture biochemical information without staining. However, the long mid-infrared optical wavelengths make the spatial resolution of photoacoustic microscopy significantly poorer than that of conventional confocal

Single Element-Based Dual Focused Photoacoustic Microscopy

Photonics, 2015
We present a single element-based dual focused photoacoustic microscopy (PAM) that shows improved signal-to-noise ratio and lateral resolution compared to conventional single focused PAM in the out-of-focus region.

Spatiotemporally Controlled Sequential Chemo‐Immunotherapy Activates Pyroptosis for Robust Anti‐Tumor Immunotherapy

Advanced Science, EarlyView.
A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...
