Magnetism Shepherds Microlenses to Excavate 'Nanocavities'
DURHAM, N.C., April 12, 2006 -- A Duke University engineer is "herding" tiny lenses with magnetic ferrofluids, precisely aligning them so they focus bursts of light to excavate patterns of cavities on surfaces. Such photolithographically produced "nanocavities" -- each only billionths of a meter across -- might serve as repositories for molecules engineered as chemical detectors, said Benjamin Yellen, an assistant professor of mechanical engineering and materials science at Duke's Pratt School of Engineering. Alternatively,...
