STAMPing out Inflammation
Mounting evidence suggests that inflammatory signaling pathways are central players in the pathogenesis of insulin resistance and type 2 diabetes. In this issue, Wellen et al. (2007) identify STAMP2 as a factor that integrates inflammatory and nutritional signals with metabolism.
متن کاملMonitoring enzymatic degradation of pericellular matrices through SERS stamping.
We introduce a surface enhanced Raman spectroscopy (SERS) stamping approach for acquiring cell-surface specific vibrational spectra of individual living cells under physiological conditions. The SERS stamping approach utilizes a nanostructured metal surface on top of a lithographically defined piston that can be translated in 3-dimensions with nanometer resolution to contact living cells in sol...
متن کاملTopUp SERS Substrates with Integrated Internal Standard
Surface-enhanced Raman spectroscopy (SERS) is known as a molecular-specific and highly sensitive method. In order to enable the routine application of SERS, powerful SERS substrates are of great importance. Within this manuscript, a TopUp SERS substrate is introduced which is fabricated by a top-down process based on microstructuring as well as a bottom-up generation of silver nanostructures. T...
متن کاملTowards quantitatively reproducible substrates for SERS.
There is a need for a method to facilitate the development of novel, reproducible colloidal surface-enhanced Raman scattering (SERS) substrates to encourage the use of SERS in applied studies. In this study we show for the first time that by using suitably designed SERS experiments in conjunction with multivariate analysis of variance (MANOVA), an objective assessment of colloidal SERS reproduc...
متن کاملTargeting Biological Sensing with Commercial SERS Substrates
There is an increasing need and challenge for early rapid and accurate detection, identification, and quantification of chemical, biological, and energetic hazards in many fields of interest (e.g., medical, environmental, industrial, and defense applications). Increasingly to meet these challenges, researchers are turning interdisciplinary approaches combining spectroscopy with nanoscale platfo...
