Au@Pt NCs nanozyme-based multichannel sensor array coupled with smartphone for selective identification and on-site detection of imidacloprid.
As a widely applied neonicotinoid insecticide, imidacloprid (IMI) necessitates portable residue monitoring to ensure food safety. Herein, a multichannel colorimetric sensor array was developed for selective IMI identification and quantification, employing Au@Pt nanoclusters (Au@Pt NCs) as the sole nanozyme sensing rece...
