这个简单，快速，安全的实验室练习的目的是为本科生提供一个介绍纳米技术使用纳米粒子（NP）合成。为学生提供了两个程序，允许合成不同但尺寸可控的银纳米颗粒。在准备好纳米粒子后，学生们进行紫外可见光谱和半高全宽（fwhm）分析，以确定他们合成的纳米粒子的大小。在这样做的过程中，学生们制作了尺寸范围从10-100纳米的纳米颗粒，从而跨越了纳米技术的范围。实验的目的是在一个单一的90分钟的会议完成，并已成功地进行了超过1000名一年级的学生在三年的时间。
The aim of this simple, quick, and safe laboratory exercise is to provide undergraduate students an introduction to nanotechnology using nanoparticle (NP) synthesis. Students are provided two procedures that allow for the synthesis of different yet controlled sizes of silver NPs. After preparing the NPs, the students perform UV–visible spectroscopy and full-width-half-maximum (fwhm) analysis to determine the size of the NPs they have synthesized. In doing so, the students made nanoparticles of size ranges from 10–100 nm, thus spanning the range of nanotechnology. The experiments are designed to be accomplished in a single 90 min session and have been successfully conducted with over 1000 first-year-level students over a three-year period.
