Effect of graphene substrate on the SERS Spectra of Aromatic bifunctional molecules on metal nanoparticles
Lopez-Ramirez, Maria Rosa
; Castro, Jose Luis; Arenas, J.F.; Soto-Martin, Juan; Otero, J.C. (2016-06-27)
The design of molecular sensors plays a very important role within nanotechnology and especially in the development of different devices for biomedical applications. Biosensors can be classified according to various ... -
Fundamentals and Applications of Surface-Enhanced Raman Spectroscopy (SERS)
Lopez-Ramirez, Maria Rosa; Otero-Fernandez-de-Molina, Juan Carlos; Soto-Martin, Juan; Castro, Jose Luis; Arenas, Juan F. (2019-05-16)
When a molecule is adsorbed on some metallic nanostructured surfaces such as silver, copper or gold, it can undergo an enormous enhancement of the Raman signal giving rise to the so called Surface-Enhanced Raman Scattering ... -
Highly effective SERS nanopattern substrate. The enhancement is demonstrated using thiophenol as a molecular probe
Lopez-Ramirez, Maria Rosa; Guerrero, A.R.; Castro, Jose Luis; Otero-Fernandez-de-Molina, Juan Carlos; Aroca, R.F. (2014-07-31)
The number of different types of Surface-enhanced Raman Scattering (SERS) substrates available for experimentation is increasing at high speed. New alternatives are introduced and explored every year in the literature ... -
Raman, SERS and DFT study of chemically-adsorbed thiobenzoic acid on silver nanoparticles
Lopez-Ramirez, Maria Rosa; Arenas, Juan Francisco; Otero-Fernandez-de-Molina, Juan Carlos; Castro, Jose Luis (2014-03-27)
Thiocarboxylic acids are organosulphur compounds with general formula RC(O)SH. They are related to carboxylic acids by the replacement of one oxygen by sulphur. Two tautomers are possible, written as RC(S)OH and RC(O)SH. ... -
SERS study of thiocarbonyl compounds adsorbed on metal nanoparticles
Otero, JC; Castro, Jose Luis; Lopez-Ramirez, Maria Rosa; Roman-Perez, Jessica (2015-06-03)
Thiocarbonyl compounds have been reported to exhibit interesting biological and pharmacological properties but they are many often characterized by their toxicological effects. However the chemistry of thiobenzoic acid ... -
Surface-Enhanced Raman spectroscopy of thiobenzoic acid on metal nanoparticles
Lopez-Ramirez, Maria Rosa; Arenas, Juan Francisco; Otero-Fernandez-de-Molina, Juan Carlos; Castro, Jose Luis (2014-07-31)
Molecules adsorbed on some metal surfaces such as silver, copper and gold, can exhibit enormous Surface-enhanced Raman Scattering (SERS). The SERS effect has historically been associated with substrate roughness on two ... -
