Nanotechnology-Based Protein Biomarker Assays: Improved Diagnostics of the Future

National Cancer Institute’s Alliance for Nanotechnology in Cancer has finally released this month’s special feature paper titled Nanotechnology-Based Assays for Validating Protein Biomarkers. As the paper states, nanotechnology offers some unique diagnostic capabilities for developing highly sensitive and selective assays. The paper gives some fascinating examples of nanotech being applied to improve the specificity and sensitivity of assays, in the case of the already commonly used prostate-specific antigen (PSA).
