New Label-Free Technique Detects Single Proteins; May Open New Future in Clinical Diagnostics

Now researchers at Brooklyn’s Polytechnic Institute of New York University (NYU-Poly) have created the first label-free system capable of detecting single protein molecules, including biomarkers for cancer and other diseases that are much smaller than any viruses. So far they demonstrated the technique on two proteins, including thyroglobulin, a human cancer biomarker, and believe the technology will be able to detect considerably smaller proteins.
