We have developed a microarray-based biosensing technique for the direct detection of nucleic acid and protein biomarkers. This technique utilizes interferometric reflectance imaging and functionalized gold nanoparticles to label and rapidly detect specific single biomolecules, and can directly detect femtomolar concentrations of specific biomarkers in under one hour. This platform technique is currently being investigated for a variety of potential point-of-care molecular diagnostic applications.
