Subject: Pyralene C and Biocompatible materials needed


Dear MEMS community,

I am looking for a biocompatible material, which is deposited easily,
by spin-coating for instance, and offers good durability for
microfluidic devices.

1. Could anyone tell me what materials are considered to be
biocompatible? PMMA (make solution 20 to 150 g/liter in Xylene, or other
high boiling point solvents)
                        Polycarbonate (benzene, Iso butyl acetate, xylene)

2. Parylene C is often reported to be one of them, and it is said to be
vapour deposited.  Does this mean, it is deposited by Chemical Vapour
Deposition?

3. Are the following biocompatible: glass (YES), silicone rubbers (YES, MOST
OF THEM), PMMA? (GENERALLY YES, DEPENDS ON ADDITIVES)


Thank you very much for your time.
