From Cold to Hot: Nanozyme‐Based Strategies for Reprogramming the Tumour Immunoenvironment

Cell Proliferation, EarlyView.
Nanozymes, with multi‐enzyme catalytic activities, reprogram the immunosuppressive tumour microenvironment by inducing immunogenic cell death, relieving hypoxia, and depleting antioxidants, effectively converting immunologically “cold” tumours into “hot” ones to boost cancer immunotherapy efficacy.

Alkaline Leaching: A Facile Surface Activation Strategy to Improve the Reactivity of Air Electrodes for Solid Oxide Fuel Cells

Advanced Materials, Volume 38, Issue 33, 12 June 2026.
This study shows that alkaline leaching of PrBa0.8Ca0.2Co2O5+δ under anodic bias selectively removes Ba and Ca, forming a cobalt‐rich and amorphous layer. The modified surface significantly boosts ORR activity, offering a simple and effective strategy to improve electrochemical device performance.

NANOCATALYSTS-NOVEL NANOENTITIES

Journal of Bio Innovation
Because of their special qualities, nanocatalysts are employed to accelerate catalytic reactions. It is a better option for catalysis because of features like exposed active sites and a larger surface area than conventional catalysts. Metal, metal oxide, and hybrid nanocatalysts are the three standard categories for nanocatalysis.

Protein Corona Composition of Gold Nanocatalysts

ACS Pharmacology & Translational Science
The interaction between nanoparticles (NPs) and biological environments is profoundly influenced by a stable, strongly adsorbed "hard" protein corona. This corona significantly determines the NPs' pharmacokinetics and biological destiny. Our study delves into the mechanisms by which colloidal Au nanocrystals that are synthesized electrochemically ...
