Microlasers Track Cells from the Inside
ST. ANDREWS, Scotland, July 24, 2015 — Embedded microlasers could allow scientists to track and distinguish between several hundred thousand cells simultaneously. The approach could enable new forms of cell tracking, intracellular sensing and adaptive imaging, according to researchers at the University of St. Andrews. Cells implanted with microlasers remain viable for several weeks, the researchers said. "This miniaturization paves the way to applying cell lasers as a new tool in biophotonics," said professor Malte
