Abstract

The use of a nanoscale DNA-Au dendrimer as a signal amplifier was proposed for the universal design of functional DNA-based ultra-sensitive SERS biosensors. This novel design combines the high specificity of functional DNA with the high sensitivity of surface-enhanced Raman scattering (SERS) spectroscopy, resulting in sensitivity superior to that of previously reported sensors.
