Abstract for Presentation

Biodegradable materials for electronic medicine and biosensors



   Biodegradable electronics is a new category of devices that can be completely degradable in physiological environments and therefore eliminate secondary surgeries for device retrieval and minimize associated infection risks. These devices could play a critical role in many therapeutic and diagnostic processes, including promoting tissue regeneration, probing neurotransmitters, etc. Here, we propose novel materials strategies and fabrication schemes that enable a fully biodegradable and self-electrified conduit device for sciatic nerve regeneration. Successful nerve regrowth and motor functional recovery are achieved in rodents. In another example, real-time detection of nitric oxide in biological systems based on degradable materials integrating wireless modules is realized, which could offer essential information for monitoring inflammatory responses. These works provide new routes for modulating and probing important biological activities that can be beneficial for healthcare.
