New technology could launch biomedical imaging to next level
Much like the checkout clerk uses a machine that scans the
barcodes on packages to identify what customers bought at the store, scientists
use powerful microscopes and their own kinds of barcodes to help them identify
various parts of a cell, or types of molecules at a disease site. But their
barcodes only come in a handful of "styles," limiting the number of
objects scientists can study in a cell sample at any one time.
