Detection of proteins—we know how to build better locks for chemical keys

It will be increasingly difficult for protein molecules to remain anonymous, and increasingly easy for doctors and patients to detect the early stages of latent diseases. Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw and the University of North Texas in Denton have perfected a method of producing thin detecting films that are able to recognize specific proteins. This is an important step towards the construction of low-cost chemical sensors, ident
