Soft materials are advantageous in terms of physical properties being close to those of biological tissues, than rigid engineering materials. Brain interfaces and nerve interfaces pose different technical challenges due to the differences in geometry and locations to apply. We introduce various brain interfaces and nerve interfaces, including their fabrication and in-vivo experiments for long-term neuronal signal recording as well as for selective stimulation.

However, initial burst, onset time, membrane rupture, conformal contact with tissue, tissue damage and foreign body responses are still the limitations of the existing drug delivery implants. Previously, we proposed and successfully fabricated a soft and flexible polydimethylsiloxane (PDMS)-based balloon-type implantable drug delivery device for a long-term controlled release to minimize the initial burst, onset time, risk of membrane rupture, tissue damage, and better conformal contact with biological tissues [2]. In addition, based on the PDMS membrane thickness the release kinetics profile was successfully demonstrated as the PDMS membrane thickness decreased, the release rate was substantially increased. In this study, we further investigated the release kinetic profile based on the mixing ratio of PDMS and analyzed the in-vitro cytotoxicity of the developed drug delivery device.
