Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

Laser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application

Responsive Materials, EarlyView.
Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in

Programmed enhancement of endogenous iron-mediated lysosomal membrane permeabilization for tumor ferroptosis/pyroptosis dual-induction

Nature Communications
Ferroptosis and pyroptosis, as emerging regulated forms of cell death capable of overcoming apoptotic resistance, demonstrate promising potential in tumor therapy. Given that iron manipulation and reactive oxygen species elevation serve as common stimuli

Phototherapies mediated by metallic nanoparticles and near‐infrared radiation in skin cancer: A systematic review

Photochemistry and Photobiology, EarlyView.
Recent studies demonstrate that near‐infrared (NIR—750–980 nm)‐mediated photodynamic (PDT) and photothermal (PTT) therapies, combined with metallic nanoparticles (MNPs), show promising results against skin cancer, particularly melanoma, in both in vitro and in vivo models.
