Dustin W. Janes

can you coat them in a conductive film like PEDOT:PSS

Alec McCarthy

Dustin W. Janes Im going to give it a try. Only concern is the toxicity.

Adeyinka Aina

For PLGA, you might want to try different stoichiometric combinations of the co-polymers, e.g. 50/50, 70/30, 60/40 etc, as this does affect some of its intrinsic properties.
