Silver coated aluminium microrods as highly colloidal stable SERS platforms.
نویسندگان
چکیده
We report on the fabrication of a novel material with the ability to remain in solution even under the very demanding conditions required for structural and dynamic characterization of biomacromolecule assays. This stability is provided by the increase in surface area of a low density material (aluminium) natively coated with a very hydrophilic surface composed of aluminium oxide (Al(2)O(3)) and metallic silver nanoparticles. Additionally, due to the dense collection of active hot spots on their surface, this material offers higher levels of SERS intensity as compared with the same free and aggregated silver nanoparticles.

SERS-active silver colloids prepared by reduction of silver nitrate with short-chain polyethylene glycol
We report a fast, one-step, facile, and green preparation method that yields very stable and biocompatible silver colloids that are highly active as surface-enhanced Raman spectroscopy (SERS) platforms that has a possible application in biomedicine. Reduction of silver nitrate has been carried out using polyethylene glycol (PEG) which acts as both reducing agent and stabilizer. It turned out th...
متن کاملHighly reproducible and sensitive surface-enhanced Raman scattering from colloidal plasmonic nanoparticle via stabilization of hot spots in graphene oxide liquid crystal.
Although it is now well recognized that plasmonic gold/silver nanoparticle based aggregates having electromagnetic hot spots are responsible for high sensitivity in surface-enhanced Raman spectroscopy (SERS), the high yield and reproducible production of such nanostructures are challenging and limit their practical application. Here we show a graphene oxide (GO) based approach in generating sta...
متن کاملSERS Technique for Rapid Screening and Species Identification of E. Coli, Listeria, and Salmonella
Techniques for routine and rapid screening of the presence of foodborne bacteria are needed, and this study reports the feasibility of citrate-reduced silver colloidal SERS for identifying E. coli, Listeria, and Salmonella. Relative standard deviation (RSD) of SERS spectra from silver colloidal suspensions and ratios of P-O SERS peaks from small molecule (K3PO4) were used to assess the reproduc...
متن کاملRaman Study of the Photochemistry of Maleic Acid Adsorbed on the Surface of Colloidal Silver
The surface-enhanced Raman scattering (SERS) spectra of maleic (cis; 2-butaneoic acid) and fumaric (trans; 2-butaneoic acid) acids adsorbed on aqueous silver sol particles are reported. These two acids form two groups of isomers which differ only in the relative positions of the two carboxylate groups. The photochemistry of maleic and fumaric acids adsorbed on the surface of silver colloids...

There is a need for new strategies for noninvasive imaging of pathological conditions within the human body. The approach of combining the unique physical properties of noble-metal nanoparticles with their chemical specificity and an easy way of conjugation open up new routes toward building bio-nano-objects for biomedical tracking and imaging. This work reports the design and assessment of a n...
