The present work reports the synthesis of water-dispersible polypyrrole (WD-PPy) and polythiophene (WD-PTh) copolymers in different weight ratios and their characterization using experimental and theoretical techniques. The copolymers were spectroscopically characterized using experimental 13 C-NMR, FTIR, and UV-visible studies, and theoretical FTIR and UV-visible studies. The theoretical frequency and UV-visible data were computed using Gaussian 09 software with the functional DFT/B3LYP method and 6-31G(d) basis set. For the first time, biophysical interaction studies were carried out using bovine serum albumin (BSA) and human serum albumin (HSA) for these polymers which are not yet reported in the literature. The results showed strong binding of the co-oligomers with BSA/HSA which could be utilized in designing potent inhibitors and biosensors.

Recent advances in the utilization of polyaniline in protein detection: a short review

https://doi.org/10.1039/D2RA05893F

Riaz, Ufana ; Nabi, Nuzhat ; Pointer, India ; Kumar, Amit ; Taylor, Darlene. K. ( November 2022 , RSC Advances)

Various reports have been published based on covalently attaching biomolecules to polyaniline (PANI). The functional groups connected to the surface of polymeric units determine the immobilization method as well as the method of detection. The present mini-review aims at covering recent advances in the field of protein binding and detection using PANI. Several proteins have been attached to the polymer using different immobilization techniques. The application of PANI in protein detection has also been discussed along with the future scope of these materials in diagnosis and detection.
