Abstract:
Rutin, a naturally occurring flavonoid compound, possesses notable antioxidant properties along with anti-inflammatory and antiviral effects. This research aimed to improve the selectivity and high fluorescence behavior of novel nanomaterial BPGQDs@NaV, which was synthesized by hydrothermal methods. Through comprehensive characterization utilizing TEM, SEM, XRD, EDS, FT-IR, UV-Vis, TCS-PC, and XPS techniques, the prepared BPGQDs, NaV, and BPGQDs@NaV were thoroughly examined. The resulting BPGQDs@NaV nanomaterials demonstrated stable, reproducible fluorescence responses and exhibited selective recognition capabilities towards rutin. The sensor developed in this study displayed remarkable performance in rutin detection, offering a broad linear range from 5 to 110 nM and an outstanding detection limit of 15.16 nM. A computational study was used to examine energy, stability, band gap, and how rutin interacted with the BPGQDs@NaV, and it also favored the detection mechanism. A portable smartphone-based sensor was also developed for the detection of rutin.
