We are primarily interested in designing Carbon
Nanotube (CNT) based nano-bio-materials and devices. Current projects
include:
- Carbon Nanotube (CNT) Synthesis, Processing, and Manipulation
Our research focuses on development of new Chemical Vapor Deposition
(CVD) synthesis methods to obtain diameter controlled CNTs with high
yield and high purity. Microfabrication and chemical functionalization
will further render ordered CNT architectures on surfaces. We are
exploring bio-molecule directed methods for CNT self-assembly and
extrapolating its potential for large-arrayed nanoscale electronic
devices.
- Single-Walled CNT (SWNT) Bio-Materials
Designing SWNT-bio hybrid structures to impart specific
bio-functionalities while maintaining the extraordinary physical and
chemical properties of SWNT is the objective. This research is cutting
edge in the field of nanobiotechnology and is envisioned to provide
revolutionary new tools for bio-analysis, drug delivery, disease
diagnostics and therapy. Currently, we are developing SWNT nanoprobes
for molecular imaging and SWNT film for cell patterning and tissue
grafting. Through Raman spectroscopy, Confocal fluorescence microscopy,
AFM, and other metrology methods, we are seeking answers to the
fundamentals that govern the interactions of SWNT with other molecules
in solution phase.
- SWNT Field Effect Transister (SWNT-FET) Biosensor
This research is aimed at developing a new generation of SWNT-FET based
biosensors. Specific objectives include: fabrication of large SWNT
sensor arrays with highly unifrom pristine electrical properties;
fabrication of ultra-sensitive SWNT nano-sensors capable of
single-molecule\ detection; development of lab-on-a-chip bio-processors
with integrated SWNT sensors, micro-fluidics, and CMOS circuitry for
multiplex addressing.
