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

open access: yesCell 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.

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

open access: yesThe FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Influence of Secondary Brown Carbon Aerosol Lifetime on Radiative Properties

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Brown carbon (BrC), a light‐absorbing organic aerosol, exhibits higher absorption coefficients at short wavelengths. Partial BrC can be formed via secondary process. In this study, we isolated the secondary BrC (σabs,sec BrC) between urban surface and mountain stations (which receive surface pollutants during convective mixing) to investigate ...

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

open access: yesAdvanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Plasmonic–Diamond Hybrids: Tunable Optical and Thermal Response for Nanoscale Applications

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
Finite‐element simulations demonstrate that nanodiamond cores precisely regulate plasmonic coupling, absorption, electric‐field confinement, and photothermal heating in gold and silver nanoparticle clusters. By identifying interparticle spacing, particle number, core conductivity, and surrounding refractive index as key design parameters, this work ...
