Abstract

A solid film structure formed of multiple solid film insert layers each having different functionality is provided. The solid film structure forms a bio-chemotronic structure having an actuator thin film layer with one or more low molecular weight organic active agents that may be activated, a sensor thin film layer that includes one or more sensors for measuring a direct or indirect response from a target to the one or more active agents, and a control thin film layer configured to individually control activation of the active agents in the actuator layer, e.g., according to a protocol.
