Scientists Guide Immune Cells With Light and Microparticles
November 15, 2009
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.
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) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
