Abstract

Sensing of analyte molecules via monitoring the turn-on fluorescence produced by magneto-luminescent and plasmonic nanoassembly for the analyte, when present in aqueous medium is depicted in this study. Donor–acceptor FRET phenomenon first provides a turn-off fluorescence followed by a turn-on fluorescence exhibited as a consequence of meisenheimer complex formation between the functionalized AuNp of the nanoassembly and nitro groups of the analyte. Here, UV–Visible, Photoluminescence, TCSPC, TEM, DLS, zeta potential, and FT-IR analytical techniques were employed for substantiating the observed phenomenon.
