NYU physicists find way to explore microscopic systems through holographic video
Date:7/20/2009

ze, the challenge for researchers is to determine if these beads actually stick to the target molecules. The way this is traditionally done is to create yet another moleculeor tagthat binds to the target molecule. This tag molecule, time-consuming and costly to produce, is typically identified by making it fluorescent or radioactive.

The holographic imaging technique, with its magnification and recording capabilities, allows researchers to observe molecular-scale binding without a tag, saving both time and money. Requiring just one microscopic bead to detect one type of molecule, holographic video microscopy promises a previously unattainable level of miniaturization for medical diagnostic tests and creates possibilities for running very large numbers of sensitive medical tests in parallel.
