Project Leader: Project 2, Professor of Chemistry (Stanford)
Dr. Dai is one of the world's leaders in carbon nanotube synthesis, characterization and device applications. He has pioneered patterned synthesis of nanotubes to obtain controllable nanotube architectures. He is the first to demonstrate nanotube sensors, and his nanotube FETs with high-k gate insulators represent the most advanced nanotube transistors to date [Javey et al., Nature Mat. 2002, 1, 241]. His group's original effort on nanotube sensors [Kong et al, Science, 2000] represents the beginning of nanosensor research worldwide currently. His nanotube sensors exhibit demonstrated sensitivity of down to 100 ppt [Qi et al., Nano Lett., 2003], and he has published one of the first papers on real-time protein sensing with high sensitivity and selectivity [Chen et al., PNAS, 2003, 100, 4984]. Dr. Dai's research interfaces with chemistry, physics, materials science,and biophysics. He is interested in solid state and soft biological materials that have well-defined atomic structures. Ongoing projects include developing new synthetic routes to ordered nanomaterial architectures; electrical, mechanical, electromechanical, and electrochemical characterizations at the nanoscale; and probing the interactions between biological molecules and nanoscale inorganic materials. His synthetic strategy involves the combination of inorganic growth methods and microfabrication or soft lithography techniques. He is also a pioneer in studying the interfaces between various molecules and nanotubes and developing biological applications of nanotubes including biosensors and molecular transporters for drug delivery applications. These may lead to potentially useful miniaturized chemical and biochemical sensors with high sensitivity and specificity, as well as novel biological carriers with unique functions.
