Opendrop Elisa: Surface Development For Digital Microfluidic Elisa Testing, Michaela Q. Mead, Madeline G. Jackson, Jacob G. Taylor

Biomedical Engineering

This project aimed to develop a process to create a hydrophobic coating with capture antibodies attached. This process was developed in an attempt to create a digital microfluidic platform upon which an enzyme-linked immunosorbent assay (ELISA) could be run, indicated for clinicians and educators in low-resource settings. Four requirements dictated the course of the design process: 1) the contact angle with water of the hydrophobic layer must be greater than 90º, 2) the colorimetric response of a positive ELISA result on our platform must be at least 85% of that run on polystyrene with the same result, 3) the platform …
