| Abstract Title: |
W31 - Diffusion in Microfluidic Structures |
| Abstract: |
This is a hands-on workshop in which the workshop leader and participants run through the steps involved in the microfluidics diffusion experiment, one of eight short experiments developed to accompany a junior level biophysics course at the Johns Hopkins University. This particular experiment has participants using a "lab on a chip" to measure molecular diffusion in water, from which a value for Boltzmann's constant can be found. The concepts of Reynolds number and laminar flow, diffusion, viscous drag, and Einstein's relation underlie this experiment. Video capture with a microscope, analysis of the image data, least-squares fitting, and using microfludic structures to manipulate molecules are some of the techniques utilized. The entire experiment can be assembled from commercially available apparatus and parts. |
