We are developing microfluidic devices that deliver reagents to islets of Langerhans in complex temporal patterns to investigate how they respond. High speed separations with MS or optical detection are often employed. Example publications are:
The fabrication of glass microfluidic devices can be tricky, especially when attempting to make shallow channels. Follow this link to a protocol that we have used with good success in making glass microfluidic chips. This protocol has been published and should be cited if used:
