PDMS Isopropanol Microfluidics

Full procedure can be found at: https://education.mrsec.wisc.edu/pdms... Microfluidics deals with the precise control of fluids on the microscale. Often at the microscale, less reagents are used resulting in faster and less expensive laboratories. In this experiment, a fluidic channel is created by casting the PDMS on a master made with puffy paint. PDMS is cured by an organometallic crosslinking reaction to give an optically transparent polymer. Different colored isopropanol is dispensed into the channels to observe fluid mixing.
