Nanomaterials

Nanomaterials are materials with at least one of their three dimensions limited to nanometer, that is, a scale that quantum effects emerge. Two-dimensional (2D) materials is a class of nanomaterials with outstanding electrical, mechanical, chemical, and bio-transducing properties. Using methods based on chemical vapor deposition, 2D materials can be prepared in large scale (~ m) and high quality with tunable strength, transparency, disorder density, and electron transport properties.

Development of High-Performance 2D-Bio Interface Technologies

Interfacing biosystems with 2D materials by developing 2D-enabled biosensing devices and systems provides significant opportunities for interrogating the life activities and biological/physiological properties (pH, electrostatic potential, structure & function, concentration, etc.) of biosystems with unprecedented sensitivity, spatiotemporal resolution, and efficiency in power, size, cost, and time. 

Translation of 2D-Based Biosensors

Device structures based on 2D materials can be translated into precise, point-of-use, portable (PPP) biosensing tools for healthcare, screening/diagnosis of diseases such as HIV and cancer, or even environmental monitoring. Another application of 2D-based devices/systems is implantable arrays of graphene microelectrodes for chronic monitoring of life activities/effects.
