Biosensor Design

Application ID: 10428

Surface reactions with adsorption-reaction-desorption steps are common in for example photocatalysis and biosensors. A flow cell in a biosensor contains an array of micropillars for adsorption of for example antigens in aqueous solutions. A signal proportional to the surface coverage can be detected in a sensor, for example through chemiluminescence.

This demo app features a flow cell with active surfaces. The app allows the user to change design parameters of the sensor such as pillar diameter, grid spacing, and inlet velocity, and see how it affects the detection results.

This application is included as an example in the following products:
