Journal ArticleDOI
Biosensing with plasmonic nanosensors
TL;DR: This paper introduces the localized surface plasmon resonance (LSPR) sensor and describes how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation.
Journal ArticleDOI
Rapid detection of an anthrax biomarker by surface-enhanced Raman spectroscopy.
TL;DR: The speed and sensitivity of this SERS sensor indicate that this technology can be used as a viable option for the field analysis of potentially harmful environmental samples and the shelf life of prefabricated AgFON substrates can be as long as 40 days prior to use.
Journal ArticleDOI
In vivo glucose measurement by surface-enhanced Raman spectroscopy.
Douglas A. Stuart,Jonathan M. Yuen,Nilam C. Shah,Olga Lyandres,Chanda Ranjit Yonzon,Matthew R. Glucksberg,Joseph T. Walsh,Richard P. Van Duyne +7 more
TL;DR: This paper presents the first in vivo application of surface-enhanced Raman scattering (SERS), which was used to obtain quantitative in vivo glucose measurements from an animal model.
Journal ArticleDOI
Real-time glucose sensing by surface-enhanced Raman spectroscopy in bovine plasma facilitated by a mixed decanethiol/mercaptohexanol partition layer.
Olga Lyandres,Nilam C. Shah,Chanda Ranjit Yonzon,Joseph T. Walsh,Matthew R. Glucksberg,Richard P. Van Duyne +5 more
TL;DR: The DT/MH-functionalized surface has greater temporal stability, demonstrates rapid, reversible partitioning and departitioning, and is simpler to control compared to the tri(ethylene glycol) monolayer used previously, indicating the rapid interaction between the SAM and glucose that is essential for continuous sensing.
Journal ArticleDOI
Glucose Sensing Using Near-Infrared Surface-Enhanced Raman Spectroscopy: Gold Surfaces, 10-Day Stability, and Improved Accuracy

TL;DR: This research compares the long-term stability of gold to silver film over nanosphere (AuFON, AgFON) substrates functionalized with a partitioning self-assembled monolayer (SAM) using both electrochemical and SERS measurements to find AuFONs were found to be stable for at least 11 days.
