Here, using the (Au/TiO2)-catalyzed reduction of 4-nitrothiophenol as a probe reaction, a catalysis/SERS bifunctional composite fabricated by uniformly dispersing catalysis-active Au nanoclusters (∼2 nm) on a SERS-active TiO2 photonic microarray was successfully applied to the non-plasmonic SERS self-monitoring of a catalytic reaction for the first time, which is superiorly sensitive and interf...

Somatosensory evoked responses (SERs) to mechanical stimulation were recorded in 5 patients with occupational vibration disease and 10 grader drivers, and the results were compared with those obtained from 48 normal subjects. SERs were recorded at room temperature of 20-23 degrees C and after immersing the hand in hot (40 degrees C) or cold (10 degrees C) water for 5 minutes. SERs were also rec...

Simplicity and low cost has positioned inkjet paper- and fabric-based 3D substrates as two of the most commonly used surface-enhanced Raman spectroscopy (SERS) platforms for the detection and the identification of chemical and biological analytes down to the nanogram and femtogram levels. The relationship between far-field and near-field properties of these 3D SERS platforms remains poorly unde...

OBJECTIVES/HYPOTHESIS Assess the reliability of a Sleep Endoscopy Rating Scale (SERS) and its relationship with pediatric obstructive sleep apnea (OSA) severity. STUDY DESIGN Retrospective case series of pediatric patients who underwent drug-induced sleep endoscopy (DISE) at the time of surgery for OSA from January 1, 2013 to May 1, 2014. METHODS Three blinded otolaryngologists scored obstr...

Dye conjugation is a common strategy improving the surface enhanced Raman detection sensitivity of biomolecules. Reported is a proof-of-concept study of a novel surface enhanced Raman spectroscopic tagging strategy termed as acid-cleavable SERS tag (ACST) method. Using Rhodamine B as the starting material, we prepared the first ACST prototype that consisted of, from the distal end, a SERS tag m...

Monitoring enzyme kinetics is an important aspect of biochemistry and is essential when studying metabolism. In this study we demonstrate that succinate dehydrogenase activity of mitochondria can be analyzed quantitatively by surface enhanced Raman scattering (SERS). We used the artificial electron acceptor reporter molecule 2,6-dichlorophenolindophenol (DCPIP) that when oxidized is SERS active...
