Abstract:Surface-enhanced Raman scattering (SERS) is a technique used to distinguish the constitution of disease-related biomarkers in liquid biopsies, such as exosomes and circulating tumor cells, without any recognition elements. Previous studies using metal nanoparticle aggregates and angular nanostructures have achieved the detection of various biomarkers owing to strong hot spots and electromagnetic (EM) fields by localized surface plasmon resonance (LSPR). Although these SERS platforms enable significant enhancem… Show more
“…The Au NHAs are fabricated by the direct metal deposition method, which has already demonstrated high reproducibility in fabrication and detection in our previous study. 59 Herein, we demonstrate the simple fabrication of an Au NHA-based DEP device, and then challenge fast and reproducible particle/biomolecule trapping and detection in the visible region. 1a).…”
In this study, we experimentally demonstrated a simple, label-free, rapid, cost-effective biomolecules' trapping in visible region with combination developed gold nanohole arrays and dielectrophoresis.
