The Secret Gift of Polarized Vision - Light polarization
The development of a remotely operated, submersible FP instrument will be presented, as well as testing results of the instrument in a simulated spill set up by the US Coast Guard at the National Oil Spill Response Research and Renewable Energy Test Facility (OHMSETT). The FP instrument utilizes a laser (532 nm) to excite the oil matrix.

Compact and cost effective instrument for detecting drug ...
Several techniques for detecting chemical drug precursors have been developed in the last decade. Most of them are able to identify molecules at very low concentration under lab conditions. Other commercial devices are able to detect a fixed number and type of target substances based on a single detection technique providing an absence of flexibility with respect to target compounds.

Introduction. This article describes a general procedure for the development of fluorescence polarization (FP) assays that can detect the binding of a small fluorescently labeled peptide or oligonucleotide to a protein of interest based on the property whereby when a fluorescently labeled molecule is excited by polarized light, it emits light with a degree of polarization that is inversely ...
