NIR-Light-Active ZnO-Based Nanohybrids for Bacterial Biofilm Treatment.

Nanomaterials with antimicrobial properties triggered by external stimuli appear to be a promising and innovative substitute for the destruction of antibiotic-resistant superbugs as they can induce multiple disruptions in the cellular mechanism. This study demonstrates the use of squaraine (SQ) dye as the photosensitive material, activated in the near-infrared tissue-transparent therapeutic window. The dye has been covalently attached to the ZnO nanoparticle surface, forming ZnO-SQ nanohybrids.

Reinforcing effect of graphene oxide reinforcement on the properties of poly (vinyl alcohol) and carboxymethyl tamarind gum based phase-separated film.

The current study deals with the preparation and the characterization of the PVA-CMT-GO films. The PVA-CMT film was translucent in nature and smooth to touch. The addition of GO resulted in the formation of agglomerated structures.

Synthesis and characterization of polyvinyl alcohol- carboxymethyl tamarind gum based composite films.

The present study delineates the synthesis of novel composite films using polyvinyl alcohol and carboxymethyl tamarind gum. The microscopic study results confirmed the formation of composite matrices. FTIR spectroscopy suggested the occurrence of hydrogen-bonding amongst the components of the films.
