Here, detection is based on the color change of AuNPs from pink to blue followed by a red shift of LSPR absorption band in UV-vis region with the addition of vitamins B-1 and B-6 into the NPs solution. A good linear range was observed in the range of 25-1000 ngmL(-1) with detection limit of 8 ngmL(-1) for B-1 and 50-1000 ngmL(-1) with detection limit of 15 ngmL(-1) for vitamins B-6. The employment of AuNPs for detection of B-1 and B-6 vitamins in rice food samples showed remarkable abilities in terms of the simplicity, low cost, stability, reproducibility and sensitivity.</p>1 aShrivas, Kamlesh1 aNirmalkar, Nidhi1 aThakur, Santosh, Singh1 aDeb, Manas, Kanti1 aShinde, Sandip, S.1 aShankar, Ravi  uhttps://library.ncl.res.in/content/sucrose-capped-gold-nanoparticles-plasmonic-chemical-sensor-based-non-covalent-interactions
