Panoply of Fluorescence Polarization/Anisotropy Signaling Mechanisms for Functional Nucleic Acid-Based Sensing Platforms.

Fluorescence polarization/anisotropy is a very popular technique that is widely used in homogeneous-phase immunoassays for the small molecule quantification. In the present Feature, we discuss how the potential of this signaling approach considerably expanded during the last 2 decades through the implementation of a myriad of original transducing strategies that use functional nucleic acid recognition elements as a promising alternative to antibodies.
