Engineering Nanoemulsions to Maximize NIR‐II Fluorescence and Preserve Photothermal Performance of a Novel Boron Difluoride Formazanate Dye

Angewandte Chemie International Edition, EarlyView.
An oil‐in‐water nanoemulsion transforms a boron difluoride formazanate (BDF) dye into a dual‐modal imaging‐guided theranostic agent (BDF‐NE). Its nonpolar oil core maximizes NIR‐II fluorescence while maintaining strong photoacoustic contrast to guide photothermal therapy with high photostability and 66.8% photothermal conversion efficiency, achieving ...

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced 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.
