摘要

Abstract

Conventional optical probes suffer from signal degradation in aqueous media

hindering sensitive biodetection. To overcome this

newly developed water-insensitive down-shifting nanoparticles (WINPs) possess superior photophysical properties in the NIR-Ⅰ window

including high quantum yield and negligible thermal effects

permitting stable

high-contrast signal generation under low excitation power. This advantage facilitated a low-power lateral flow assay capable of highly sensitive avian influenza virus (AIV) detection in the opaque biological matrices (such as avian swabs)

mitigating interference issues relying on visible-range signals.
