What You Need to Know
The process employs food‑grade PDMS or gelatin‑based hydrogels coated with conductive graphene or silver nanoparticles, encapsulated in an edible epoxy layer. Precise thermal control (≤70 °C) and rapid application (2–3 min) preserve both protein integrity and sensor functionality while maintaining food safety standards.
