Abstract

Biocompatible packaging is crucial in developing implantable sensors. It should allow solutes of interest to diffuse through while minimizing inflammatory response to the packaging and the sensors. In this study, a cage system made of a metal mesh cylinder surrounded by a polyvinyl alcohol (PVA) sponge material was implanted into rats, and fibrotic tissue was formed around the cage system. We then experimentally investigated the permeation rate of solutes (Na, K and Cl) through the fibrotic tissue using a microfluidic device, and found that diffusion coefficients with respect to all the solutions were on the order of 10-10 m2/s, which increased with the flow rates.
