Abstract

Proteins are widely used biomarkers in disease diagnosis. A vast majority of clinical methods for the detection of the marker proteins use antibodies. Such methods are sub-optimal to function in global health applications and point-of-care assays. We are developing single-walled carbon nanotube-based optical sensors for straight-forward, rapid and sensitive measurement of proteins for accurate disease diagnosis. Single-walled carbon nanotubes, with intrinsic photoluminescence and high optical sensitivity towards molecular interactions, upon the surface modification with polymeric materials provide unmatched basis for the development of optical sensors.
