Creates catalysts to reduce the number of steps needed to synthesize drugs, diminishing environmentally hazardous by-products.
Creates catalysts to reduce the number of steps needed to synthesize drugs, diminishing environmentally hazardous by-products. He hopes one system will take the manufac-ture of Prozac, a top-selling anti-depressant drug, from four steps to just one.
Devised a new class of polymer nanotubes and other molecular building blocks. These novel materials have potential applications in the fabrication of nanosized electronic devices.
Crafts nanoparticles that would release chemicals inside the body to "program" immune cells to combat viral infections like HIV, to tolerate transplants, or even to destroy malignant tumors.
Develops microfluidics technologies that use tiny droplets to characterize the function and structure of proteins and to model complex biochemical processes.
Exploits biology-based self-assembly to build molecular electronics. She created a self-assembled molecular-electronic device -- a carbon nanotube transistor -- using a DNA template.
Etched optical bar codes into micrometer-size pieces of silicon. She hopes to use the technology to detect pollutants in water or cancerous cells within the body.
Spearheads efforts to commercialize the "plasmatron," a pollution control device that converts diesel fuel to hydrogen, cutting nitrogen oxide emissions by up to 90 percent.
Technology Review's Emerging Technologies Conference at MIT brings together world-renowned innovators and leaders to discuss the technological innovations destined to better our lives and fuel economic growth.
