We report simple and selective method for detection of vitamins B and B in brown and white rice samples using localized surface plasmon resonance (LSPR) of sucrose capped gold nanoparticles (AuNPs) as a chemical sensor colorimetrically. 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 and B into the NPs solution A good linear range was observed in the range of 25-1000 ngmL with detection limit of 8 ngmL for B and 50-1000 ngmL with detection limit of 15 ngmL for vitamins B. The employment of AuNPs for detection of B and B vitamins in rice food samples showed remarkable abilities in terms of the simplicity, low cost, stability, reproducibility and sensitivity.
我们报道了一种简单而选择性的方法，用于检测棕色和白米样品中的维生素 B 和 B，使用蔗糖封端的金纳米粒子（AuNPs）的局域表面等离子体共振（LSPR）作为化学传感器比色。在这里，检测是基于 AuNPs 从粉红色变为蓝色的颜色变化，随后在 UV-vis 区域中 LSPR 吸收带发生红移，随着 B 和 B 维生素加入到 NPs 溶液中。在 25-1000ngmL 的范围内观察到良好的线性范围，B 的检测限为 8ngmL，B 维生素的检测限为 50-1000ngmL，检测限为 15ngmL。AuNPs 用于检测米食品样品中的 B 和 B 维生素，在简单性、低成本、稳定性、重现性和灵敏度方面表现出了显著的能力。
