Sol-Gel Based micro well fabrication and protein spotting using piezoelectric dispenser

This example shows how you can spot both lines and spots using sol-gel. Sample was Dequasol HP.

Using a gel, we were able to produce microwells with the following dimensions:


The spot in the middle is 1mg/ml concentration of bovine serum albumin. This volume of the spot after drying was also measured to be 140pl:

The images generated using a CyberScan Vantage laser based non-contact inspection system from Cyber Technologies GmbH.
