A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer's, may soon be within reach -- thanks to the work of a team of Yokohama National University researchers in Japan.
As the team reports in Applied Physics Letters, from AIP Publishing, they created a photonic crystal nanolaser biosensor capable of detecting the adsorption of biomolecules based on the laser's wavelength shift.
