Integrated Surface-Enhanced Raman Spectroscopy Sensors for Process Monitoring

Zhang K., Zhang X., Rabin O., Zhang K., Zhang X., Briber R.M., von Bredow H., Metting C., Atanasoff G., University of Maryland, US

Optical metamaterials obtain their unique properties from the combination of nanoscale plasmonic components and dielectric components. Reproducible mass-production of metamaterials is challenging but desirable for applications such as surface-enhanced Raman scattering (SERS) for chemical sensing. [...]

Zinc Oxide optical and chemical sensors fabricated by Ink Jet printing and drop casting

Ewing D.J., Casper M., Stramel A., Morick B., Cook B., Wu J., The Department of Energy's Kansas City National Security Campus, US

Zinc oxide (ZnO) nanostructures show great promise for a variety of applications, such as UV detectors, chemical, and gas sensors. Zinc oxide has a direct bandgap (3.4 eV), a high electron mobility, and environmental stability. [...]

Continuous Sensing of blood by dark-field microscopy and surface-enhanced Raman Spectroscopy

Henry A.-I., Sharma B., Sagle L.B., Van Duyne R.P., Northwestern University, US

Surface-enhanced Raman spectroscopy (SERS) is a rapid, label-free technique with multiplexing capabilities, making it very relevant for the sensitive real-time detection for biomedical applications , , . Demonstration of in vivo glucose detection with unprecedented [...]
