Strategies to Functionalized Liquid Metal Surfaces For Biostable and High Performance Bioelectronc Applications.

Gallium-based liquid metal materials have emerged as a promising material platform for soft bioelectronics. Unfortunately, Gallium has limited biostability and electrochemical performance under physiological conditions, which can hinder the implementation of its use in bioelectronic devices. Our recent work has developed several methods for electrochemical deposition of functional material (carbon nanomaterials and conductive polymers) on liquid metal surfaces. In this presentation, we will discuss the depostion methods and how different functional materials can improve the biostability and electrochemical performance of gallium-based liquid metals for biosensing applications.
