Hands-on Modules

Anti-bacterial properties of silver nanoparticles

Spring Semester 2013

The final implementation of the green-nano module in the LHS-CCC TUES project focused on synthesizing and testing silver nanoparticles. To augment the module, the career workshop focused on the impact of technology on society, specifically how current and future nanotechnologies will impact people around the world.

The three-part lab involved synthesis, testing and characterization and was implemented with a collaborative model. The chemistry students synthesized silver nanoparticles using the standard Turkevich method. The biology students then tested the anti-bacterial properties of these nanoparticles with a yeast respiration experiment. Finally, the engineering students characterized the silver nanoparticles from the chemistry class with a scanning electron microscope (Hitachi’s TM3000). Students from each discipline had an opportunity to hear from the students who had performed the previous step.

Superhydrophobic copper surfaces

Fall Semester 2012

For the second module, we adapted a protocol from Larmour et al. (2007). Students created superhydrophobic and superhydrophilic surfaces by chemically modifying copper.

Dye-sensitized solar cells

Spring Semester 2012

In the first module, students created dye-sensitized solar cells (DSSC) using nano-crystalline titanium dioxide. This well-tested lab, with deep connections to nano and green technologies, was adapted by the MRSEC at University of Wisconsin, Madison into a classroom activity from the original published experiment (Gratzel, 2003).
