Multifunctional composite film of chitosan/reduced graphene oxide infused silver nanoparticle for antibacterial and cytotoxic effects on HeLa cells.

In this study, biopolymer-based nanocomposite (NC) films were developed using a solution casting method, carbonaceous nanofillers to enhance their functional properties of polymer network. Biopolymer fabrication of chitosan/polyvinyl alcohol (CS/PVA) based NC were integrating by 2D reduced graphene oxide (rGO) and silver nanoparticles (AgNPs), forming a NC film. The presence of rGO promoted uniform nucleation and stable dispersion of AgNPs, facilitating the fabrication of large surface-area NC films.

Biodegradable multifunctional fabrication of silver-doped zinc oxide nanoparticle on chitosan/polyvinyl alcohol flexible film for effective antibacterial potential and attenuation of human liver carcinoma cells.

Biopolymer-based drug delivery systems are increasingly attracting interest due to their excellent biocompatibility, non-toxic and cost-effectiveness. In this study, nanocomposite film was fabricated by silver-doped zinc oxide nanoparticles (Ag@ZnO) into chitosan/polyvinyl alcohol (CS/PVA) matrix. CS/PVA/Ag@ZnO nanocomposite film was confirmed through TEM, UV-Vis, and FTIR spectroscopy.

Influences of ionic liquid and temperature on the tailorable surface morphology of F-apatite nanocomposites for enhancing biological abilities for orthopedic implantation.

This report has approached for the green synthesis of morphological controlled novel metal-doped fluorinated apatite/polymeric nanocomposites. The synthesized nanocomposites have investigated for hard tissue engineering and bone substitute applications. The selected fluoro ionic liquid explored the dual performances as fluorine precursor and as a soft template for the morphological development of apatite nanocomposite synthesis.

Facile biological synthetic strategy to morphologically aligned CeO/ZrO core nanoparticles using Justicia adhatoda extract and ionic liquid: Enhancement of its bio-medical properties.

In this study, a typical green synthesis route has approached for CeO/ZrO core metal oxide nanoparticles using ionic liquid mediated Justicia adhatoda extract. This synthesis method is carried out at simple room temperature condition to obtain the core metal oxide nanoparticles. XRD, SEM and TEM studies employed to study the crystalline and surface morphological properties under nucleation, growth, and aggregation processes.

Photoluminescent reduced graphene oxide quantum dots from latex of Calotropis gigantea for metal sensing, radical scavenging, cytotoxicity, and bioimaging in Artemia salina: A greener route.

In this work, we report the fabrication of green fluorescent reduced graphene oxide quantum dots (rGOQDs) from the latex of Calotropis gigantea by simple one-step microwave assisted greener route. The latex of Calotropis gigantea calcined at 300°C and its ethanolic extract is used for the synthesis of QDs, The rGOQDs showed particle size ranging from 2 to 8nm and it exhibited green fluorescent in longer UV region at 360-520nm. The rGOQDs graphitic nature was confirmed by RAMAN and XRD analysis.
