Ultrasensitive detection of thiram based on surface-enhanced Raman scattering via Au@Ag@Ag core/shell/shell bimetallic nanorods
Ultrasensitive detection of thiram based on surface-enhanced Raman scattering via Au@Ag@Ag core/shell/shell bimetallic nanorods† We developed a highly sensitive and stable SERS-active substrate of Au@Ag@Ag core/shell/shell nanorods, formed by encapsulating Au nanorods (Au NRs) into a bilayer silver shell with Raman reporter molecules (4-mercaptobenzoic acid (4-MBA) and thiram) in the shell–shell gap. The core/shell/shell nanostructures demonstrated a high SERS enhancement and easy assembly.
The applications of carbon dots in oral health: A scoping review
1 INTRODUCTION From the moment that carbon dots (CDs) were discovered by chance during the synthesis of single-walled carbon nanotubes in 2004 (Xu et al., 2004), their synthesis, characteristics, and applications have increasingly been investigated. CDs are amorphous or nanocrystalline sp2 or sp3 carbon clusters with functional groups attached on their surfaces, and their size is usually <10 nm in diameter.
Carbon quantum dots as immune modulatory therapy in a Sjögren's syndrome mouse model
1 INTRODUCTION Sjögren's syndrome (SS) is a systemic chronic autoimmune disorder of the exocrine glands, especially salivary and lachrymal glands, and associated with lymphocytic infiltration of the affected glands which are responsible for sicca syndrome and systemic manifestations (Fox, 2005; Parisis et al., 2020).
Signal Amplification Surface-Enhanced Raman Scattering Immunosorbent Assay of Human Chorionic Gonadotrophin based on Repeated Enzyme Biocatalytic Precipitation
Signal Amplification Surface-Enhanced Raman Scattering Immunosorbent Assay of Human Chorionic Gonadotrophin based on Repeated Enzyme Biocatalytic Precipitation Cuicui Fu, Li Zhang, Meiqi Bao, Yue Zhang, Yalan Li, Yan Wu and Young Mee Jung Abstract A novel surface-enhanced Raman scattering (SERS) immunoassay method based on tyramine signal amplification (TSA) technology triggering the formation of enzyme repeats on an enzyme-linked immunosorbent assay (ELISA) was designed for highly sensitive...
Horseradish peroxidase-repeat assay based on tyramine signal amplification for highly sensitive H2O2 detection by Surface-Enhanced Raman Scattering
Horseradish peroxidase-repeat assay based on tyramine signal amplification for highly sensitive H2O2 detection by Surface-Enhanced Raman Scattering Cuicui Fu, Yuqiu Wang, Xue Tian, Yan Wu, Haiyan Cao, Yangyang Li and Young Mee Jung Abstract A new and simple surface-enhanced Raman scattering (SERS) biosensor based on the tyramine signal amplification (TSA)-triggered formation of horseradish peroxidase (HRP) repeats on a gold sensing chip was designed for the highly sensitive detection of...

A Simple Enzyme-Free SERS Sensor for Rapid and Sensitive Detection of Hydrogen Peroxide in Food
A Simple Enzyme-Free SERS Sensor for Rapid and Sensitive Detection of Hydrogen Peroxide in Food A simple enzyme-free method based on surface-enhanced Raman scattering (SERS) was developed for the first time to detect H2O2 in food by etching a self-assembled film of silver nanoparticles (Ag NPs) on a glass substrate. H2O2 is able to oxidize Ag NPs into Ag+ ions, which reduces the size of the Ag NPs and eventually leads to a decrease in the SERS signal of the Raman probe.
Facile Detection of Glucose in Human Serum Employing Silver-ion-guided Surface-enhanced Raman Spectroscopy Signal Amplification
A facile surface-enhanced Raman scattering (SERS) sensor based on a silver-ion-mediated amplification effect was designed for the determination of glucose concentration. In this approach, 4-aminothiophenol (4-ATP) molecules assembled on the surface of a gold wafer (Au wafer@4-ATP) act not only as Raman tags but also as linkage agents.
