From a single cell to a whole organism, the laser will play an increasingly important role in diagnosing and treating disease. So says a Duke University bioengineer who is using the latest applications of a technology invented 50 years ago to peer into the genetic material of cells, to detect the earliest signs of disease in a single cell, and to non-invasively and optically biopsy tissue inside the body for the tell-tale traces of cancer.

In addition to flows of electrons, researchers are seeking options for the spin of electrons to be used in future information processing. In combination with these characteristics, a considerably larger volume of information can be stored than merely 'zero' and 'one'. Because this is difficult with individual atoms, physicists place 'artificial atoms' into solids. Through his participation, a research team has now has succeeded in an energy-state occupancy readout of those artificial atoms - using common interfaces to classic computers.
