Three–dimensional donor–acceptor–type photoactive material/conducting polyaniline hydrogel complex for sensitive photocathodic enzymatic bioanalysis

A short review on the synthesis and advance applications of polyaniline hydrogels

“…With a wide linear range and a low sensing limit, the biosensor has demonstrated good sensing capability. Qing et al 72 synthesised poly-4,8-bis[5-(2-ethylhexyl)thiophen-2-yl] to develop a photocathodic enzymatic biosensor. The biosensor was fabricated using benzo[1,2- b :4,5- b ′] dithiophene-2,6-diyl-alt-3-fuoro-2-[(2-ethylhexyl) carbonyl] dithiophene-2,6-diyl-alt-3-fuoro-2-[(2-ethylhexyl) carbonyl] dithiophene-2, PANI hydrogel as electron transfer layer and thieno[3,4- b ]thiophene-4,6-diyl (PTB7–Th) as donor–acceptor-type photoactive material.…”

Carboxylated Cellulose as a Soft Template Combined with PEDOT Derivatives in [BMIM]Cl: A Competent Biosensor for Detection of Guanine and Uric Acid in the Blood

“…An additional peak at 289.2 eV is due to OC–O and is attributed to the carbonyl groups in CLC Figure e displays the O 1s spectra of PEDOT-MeSH with two peaks at 532.1 and 530.3 eV that are assigned to the CC and C–O bonds, respectively, while the corresponding peaks of PEDOT-MeSH/CLC are observed at 532.9 and 531.7 eV . Comparison of PEDOT-MeSH and PEDOT-MeSH/CLC results shows that a notable increase in the intensity of the CO and C–O bond peaks and a positive shift by 0.8 and 1.4 eV can be observed in the composites, and this change is also observed for PEDOT-MeNH 2 and PEDOT-MeNH 2 /CLC.…”

Polymer dots synergized with a NiO hole transporting layer and poly(amido amine) dendrimer: toward sensitive photocathodic detection of tyrosinase level in serum

“…11–16 In comparison with the well-studied photoanodic bioanalysis, 17–26 serious consideration of p-type light-harvesting materials for photocathodic bioanalysis is relatively recent. 27–31 Nevertheless, because of their desirable properties such as higher stability than the anodic system and superior anti-interference capability against reductive substances in actual biological samples, exploration in this direction is gaining strong momentum. 32 Bearing in mind the advantages of photocathodic bioanalysis and the significance of TYR, it is of particular interest to accomplish innovative photocathodic bioanalysis of TYR.…”
