Portable Fluorescence Detection Platform with Integrating Sphere*

摘要

A platform coupled with an integrating sphere for portable fluorescence detection was presented in this paper. The detector under testing has a demonstrated lower limit of detection 0.4 nM for detecting fluorescein solutions and 0.00128 ng/μL for detecting SYBR-Green stained dsDNA in this preliminary work. The signal-to-noise ratio analysis suggests that the limit of detection could be even lower than presented herein.
