Glucose sensing by stamping surface-enhanced Raman spectroscopy (S-SERS)

Biophotonics Congress: Optics in the Life Sciences Congress 2019 (BODA,BRAIN,NTM,OMA,OMP), 2019
We report glucose sensing 10 mM to 0.1 mM in water using stamping surface-enhanced Raman spectroscopy (S-SERS) technique with nanoporous gold disk (NPGD) plasmonic substrates, a reagent- and separation-free technique.

Surface Enhanced Raman Spectroscopy (SERS) optical fibers for remote sensing

Novel Biophotonics Techniques and Applications V, 2019
In this study, we present facile fabrication of a miniaturized remote sensing SERS platform using highly tunable Nano-Sphere Lithography (NSL) technique. Self-assembly at the air-water interface was performed and the monolayer of polystyrene spheres was transferred onto the tip of optical fibers.

Nanofluidic channel based biosensor using surface enhanced raman spectroscopy (SERS)

SPIE Proceedings, 2007
The Raman scattering signature of molecules has been demonstrated to be greatly enhanced, on the order of 106-1012 times, on roughened metal surfaces and clustered structures such as aggregated colloidal gold. Here we describe a method that improves reproducibility and sensitivity of the substrate for surface enhanced Raman spectroscopy (SERS) by ...

Electrochemical surface-enhanced Raman spectroscopy (E-SERS) of novel biodegradable ionic liquids

Physical Chemistry Chemical Physics, 2013
Electrochemical SERS (E-SERS) was used for the first time to study the interfacial behavior of a class of pyridinium-based biodegradable ionic liquids at a silver nanoparticle (AgNP) electrode surface. An isomeric series of ionic liquids (IL) based on 3-butoxycarbonyl-1-methylpyridinium bis(trifluoromethanesulfonyl)imide were prepared, which have ...

Expanding generality of surface-enhanced Raman spectroscopy with borrowing SERS activity strategy

Chemical Communications, 2007
Surface-enhanced Raman scattering (SERS) was discovered three decades ago and has gone through a tortuous pathway to develop into a powerful diagnostic technique. Recently, the lack of substrate, surface and molecular generalities of SERS has been circumvented to a large extent by devising and utilizing various nanostructures by many groups including ...

Detection of Pesticides and Metabolites Using Surface-Enhanced Raman Spectroscopy (SERS): Acephate

Applied Spectroscopy, 2015
A protocol created for acephate detection on particulates and vapors surrounding farmworkers as well as in urine samples is reported. Acephate is detected to the low parts-per-billion (ppb) range using surface-enhanced Raman spectroscopy (SERS). Optimal SERS sensor metal choice and post-production treatments to improve sensor stability in aqueous ...

Surface-enhanced Raman spectroscopy (SERS)-based urine biopsy for kidney transplant patients

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy
For kidney transplantation patients, monitoring potential complications such as immune rejection and infection has always been a clinical challenge since the existing detection technology faces difficulties due to limited information, insufficient sensitivity and specificity, and lack of continuous dynamic monitoring ability.
