Abstract
The study of surface and interfacial science via analytical techniques is a growing interest in the easy mode of diagnosing probe molecules adsorbed on the surface. In that line, Raman spectroscopy is an analytical method that is inefficient to carry the surface analysis employing their weak cross-sectional scattering until the discovery of Surface-Enhanced Raman Scattering (SERS) in late 1970s. SERS creates a revolution in many fields, including sensor and biomedical applications. It works, when the incident light hits on rough metal surface adsorbed on the probe molecule gets increased Raman signal in a few orders of magnitude.
Highlights
The study of surface and interfacial science via analytical techniques is a growing interest in the easy mode of diagnosing probe molecules adsorbed on the surface [1]
The prepared Rh nano-networks were analyzed and shows the strong peaks at 268 nm was further evidenced the strong interaction of deoxyribonucleic acid (DNA) with the metal ion [25]
The Surface-Enhanced Raman Scattering (SERS) enhancement factor (EF) is used determine the enhanced Raman intensity is written as [7], The trials made without any Rh nano networks, shows no peak for methylene blue (MB) clearly picturize the efficiency of the developed SERS substrate using biomolecule DNA
Summary
The study of surface and interfacial science via analytical techniques is a growing interest in the easy mode of diagnosing probe molecules adsorbed on the surface [1]. We have chosen Rh NPs prepared on bio-molecule DNA as scaffold for an active SERS substrate to carry the probe detection. Engineered Rh Nano-networks on DNA for SERS Applications.
