AIBN Seminar Series Liquid metal enabled sensors and bio-systems

Abstract

Liquid metals (LMs) are group of low melting point metals and alloys combining metallic and liquid properties. In essences, they are electronic liquid with perplexing interfacial chemistry and physics. The characteristics of LMs such as softness, electrical and thermal conductivity, as well as their unique interfacial chemistry has eclipsed various research disciplines.  These features make them promising materials for driving chemical reactions on their surfaces for designing nanoarchitectonic systems and also their bulk for developing a variety of physical units, specifically those that can be used for sensing and in bio applications. LMs interactions with live cells are unique. Utilisation of LMs as responsive interfaces, enabling sensing in a flexible and versatile manner. Additionally, responsiveness to various stimuli and easy-to-functionalize interface of LMs make them ideal candidates for many sensing applications. The talk provides an overview on the synthesis and applications of LMs based materials in a variety of bio applications and also sensing approaches including different physical and chemical systems. The unique features of LMs, which makes them promising materials in each category of sensors and a variety of bio systems, will be discussed in followed by relevant case studies.
