Poly(acrylic acid) Interpolymer Complexation: Use of a Fluorescence Time Resolved Anisotropy as a Poly(acrylamide) Probe

A low concentration Poly(acrylamide) sensor has been developed which uses the segmental mobility of another polymer probe with a covalently attached fluorescent marker. 

Today we have heard another manuscript has just been accepted by RSC Advances, written by Dr. Thomas Swift, Dr. Linda Swanson and Professor Stephen Rimmer, titled “Poly(acrylic acid) Interpolymer Complexation: Use of a Fluorescence Time Resolved Anisotropy as a Poly(acrylamide) Probe.” The paper outlines novel use of time-resolved anisotropy as a sensing technique, determining ppm concentrations of poly(acrylamide) in aqueous solutions.

Abstract:
A low concentration Poly(acrylamide) sensor has been developed which uses the segmental mobility of another polymer probe with a covalently attached fluorescent marker. Interpolymer complexation with poly(acrylic acid) leads to reduced segmental mobility which can be used to determine the concentration of polymer in solution. This technique could be useful in detecting the runoff of polymer dispersants and flocculants in fresh water supplies following water purification processes.
