Application of modifier-free gold nanoparticle colorimetric sensing for rapid screening and detection of vitamin B1

Abstract

A simple and fast alternative colorimetric sensing platform for selective determination of vitamin B1 in urine samples was proposed.

Duenchay等 [10] 通过构建一种基于金纳米颗粒(AuNPs)的比色传感平 台实现了尿液样本中VB1的准确测定, 检测限达到 3.002 ppb.…”

Progress in the design of portable colorimetric chemical sensing devices

“…Duenchay et al 55 developed flexible sensing strips for the detection of vitamin B1 in urine samples. They achieved this by depositing AuNPs on a transparency sheet.…”

Image Digitization of Colorimetric Detection of Acephate Based on Its Complexation with Citrate-Capped Gold Nanoparticles

“…RVs were attained by capturing the image of the Ac-Cit-AuNPs complex and digitizing the red colour of the captured images by ImageJ software. e RVs can effectively represent the degree of aggregation for Ac-Cit-AuNPs complex [52]. As the concentration of Ac was increased, higher degree of aggregation was expected and colour change from red (Cit-AuNPs) to purple (Ac-Cit-AuNPs) was enhanced.…”
