TL;DR: A new method of synthesis of an Au nanoparticle-conductive polyaniline composite is reported by using H2O2 both for reduction of HAuCl4 and polymerization of aniline in the same aqueous medium, with electrical conductivity measured to be two orders of magnitude higher than the polymer itself.

TL;DR: This proficient hybrid hydrogel solid sensing platform is the most suitable to employ as an on-site operational, portable, cheap colorimetric-optical detector of heavy metal ion with potential skill in their separation.

TL;DR: A robust biofilm with antimicrobial properties fabricated from chitosan-iron oxide coated graphene oxide nanocomposite hydrogel films displayed significant antimicrobial activities against both Gram-positive and Gram-negative bacterial strains, which conveyed the possibility of potential applications of these soft and tough films in biomedical as well as in the food industry.

TL;DR: In this paper, a new green source "tea" was used as precursor for carbon dots (CDs), and the electrostatic interaction of positive charge on chitosan and negative charge on CDs prepared from tea was used for the successful preparation of a stable and robust CHITOSAN-carbon dots nanocomposite hydrogel film.

TL;DR: It is found that the PPy-TiO(2) composite films catalyze the reactions in the presence of light more efficiently than a suspension of TiO( 2) NPs.
