News From the Field
Scientists Guide Immune Cells With Light and Microparticles

November 15, 2009

microparticles that mimic bacteria A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. They used holographic optical tweezers to guide "artificial bacteria"--microparticles that mimic bacteria by giving off a chemical "scent," stimulating immune cells to respond. By controlling the chemical patterns produced, they were able to study how immune cells respond to and interact with these chemical signals. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
