分光光度法和比色法实验在高中和大学化学课程中很常见，纳米技术在日常产品和新设备中越来越常见。以前的工作已经证明，手持摄像机设备可以用来量化溶液中有色分析物的浓度，代替传统的分光光度计或比色设备。本文将这种方法扩展到量化胶体金“膳食补充剂”中的金纳米颗粒的浓度。随着免费谷歌应用程序的加入，调查提供了一个可行的，复杂的实验室经验和纳米技术的介绍。
Spectrophotometry and colorimetry experiments are common in high school and college chemistry courses, and nanotechnology is increasingly common in every day products and new devices. Previous work has demonstrated that handheld camera devices can be used to quantify the concentration of a colored analyte in solution in place of traditional spectrophotometric or colorimetric equipment. This paper extends this approach to quantifying the concentration of gold nanoparticles in a colloidal gold "dietary supplement". With the addition of free Google applications, the investigation provides a feasible, sophisticated lab experience and introduction to nanotechnology.
