Research

Dr. Liu’s research is focused on the development of nanoelectronic sensors, integrated biosensing systems, and biomimetic devices using multi-disciplinary approaches.

Nanoelectronics and Electrochemical Properties of Graphene

Nanoelectronics biosensor

Characterization and electrolytic cleaning of graphene

Theoretical analysis and experimental design for investigating graphene-electrolyte interface

Study specific ions adsorption on graphene and electrolyte matrix effects

Integrated Biosensing System for Point-of-Care Rapid Detection and Diagnostics

Integrated Lateral Flow Device

Integrated lateral flow device that applied the capillary forces with functionalized polymer-based microfluidics as a strategy to realize a portable, simplified, and self-powered lateral flow device.

Dielectrophoresis for Biomarker Detection

Develop a methodology to achieve protein concentration utilizing the combination effects of electrokinetics and low frequency insulating dielectrophoresis (iDEP) generated within a microfluidic device.

Microphysiological Systems

Engineering Functional Human Microvessels

Engineered microvessels formed under perfused conditions recapitulated certain key features of the microvessels in vivo.

Biomimetic Devices for Nanotoxicity

Microfluidic gradient devices were used to study chronically nanomaterial-exposed cell migration. Multiple migration signatures of the cells' migration were extracted and investigated.
