PET-based aqueous-stable two-phase perovskite nanoprobe for quantization of capsaicin in food sample

Abstract

We introduce an innovative two-phase-perovskite-based sensing platform for the ultrasensitive detection of capsaicin via the photo-induced electron transfer mechanism, with the limit of detection as low as 0.21 nM. Importantly, the successful use of this probe for monitoring capsaicin in real samples suggests its potential utilization prospects in food sectors.
