Advances in the Design of Real-time Chemical/biochemical Sensors: Meeting Needs for the 21st Century
In recent decades, sensor research has experienced a revolution, promising to have a significant impact on a broad range of applications relating to national security, health care and medicine, the environment, energy, food safety, and manufacturing etc. One of the major research activities is to develop sensing technologies for continuous real time chemical and biosensing for extended periods. The sensors with real time and continuous sensing capability will provide immediate feedback of chemical and biological environment just like our own five senses of taste, sight, hearing, touch and smell. This presentation will discuss our strategies to develop robust and multifunctional chemical and biointerfaces that enable continuous chemical and
biosensing. It will include a few topics: (1) general theory of sensors; (2) basic characteristics and applications of sensors; (3) design of multifunctional chemical and biointerfaces in our sensing strategy to achieve in situ and real time detection of important chemical and bioanalytes with high temporal and/or spatial resolution. Our fundamental and applied research at solid/liquid/gas interfaces allows us to address many sensors challenges, especially miniaturized, real-time and continuous sensing that are essential for their integration with engineering advancements such as portable electronics, networked sensing and next-generation monolithicimplementation of autonomous sensors with the performance, cost, power, and operational
lifetime characteristics to suit a broad range of applications in health, environment and energy applications.
