Photoresists & Specialty Chemicals
Microwell Arrays
Part of the Applications Notes Line
Microwell arrays* are widely used for microfluidic diagnostics. SU-8 is being used to lithographically fabricate addressable low cost high density microwell arrays for disposable biochips. Rapid diagnostic tests can be done with luminescent based assays using dyed SU-8 fiber optic faceplates. Reducing optical cross talk improves detection sensitivity. Applications include bio-mems for genomics, proteomics, and other bio determinations.
