Abstract

A Surface-Enhanced Raman Spectroscopy (SERS) device to perform accurate label-free long-read DNA sequencing. A Raman sensor has a hot spot defined by plasmonic nanostructures and excited by at least one laser. An immobilized DNA polymerase can be used to pull a DNA template strand to be sequenced through the hot spot.
