Effective Delivery of Analytes with Optofluidics for Ultrasensitive Biodetection

Not Accessible

Your library or personal account may give you access

Abstract

We present a plasmonic nanobiosensor offering superior analyte delivery efficiency. Our experiments with virus-like analytes show more than an order of magnitude faster response time, and seven orders-of-magnitude dynamic concentration range for 103–109 particles/mL.
