Antifouling strategies for protecting bioelectronic devices

Bioelectronic devices are playing an increasingly important role in many areas of our lives. They power a significant portion of medical diagnostics and are becoming more and more important for delivery of therapeutics and monitoring of chronic symptoms. However, surface fouling phenomena, and especially biofouling in complex biological fluids, restricts the performance of these devices and severely reduces their useful lifespan. In this Research Update, we discuss the main principles and strategies that researchers use to prevent fouling and minimize or remove the foulants from bioelectronic device surfaces. We also survey a variety of antifouling approaches that can enhance device performance.

Automated summary

Bioelectronic devices play a crucial role in medical diagnostics, therapeutics delivery, and chronic symptoms monitoring, but their performance is hindered by surface fouling. Researchers are exploring principles and strategies to prevent fouling and enhance device performance through various antifouling approaches.
