Biocompatible PANI-Encapsulated Chemically Modified Nano-TiO Particles for Visible-Light Photocatalytic Applications.

Polyaniline (PANI) constitutes a very propitious conductive polymer utilized in several biomedical, as well as environmental applications, including tissue engineering, catalysis, and photocatalysis, due to its unique properties. In this study, nano-PANI/N-TiO and nano-PANI/Ag-TiO photocatalytic composites were fabricated via aniline's oxidative polymerization, while the Ag-and N-chemically modified TiO nanopowders were synthesized through the sol-gel approach. All produced materials were fully characterized.

Composite Nanoarchitectonics of Photoactivated Titania-Based Materials with Anticancer Properties.

The synthesis of titania-based composite materials with anticancer potential under visible-light irradiation is the aim of this study. In specific, titanium dioxide (TiO) nanoparticles (NPs) chemically modified with silver were embedded in a stimuli-responsive microgel (a crosslinked interpenetrating network (IP) network that was synthesized by poly (N-Isopropylacrylamide) and linear chains of polyacrylic acid sodium salt, forming composite particles. The ultimate goal of this research, and for our future plans, is to develop a drug-delivery system that uses optical fibers that could efficiently photoactivate NPs, targeting cancer cells.

Development of Smart Composites Based on Doped-TiO Nanoparticles with Visible Light Anticancer Properties.

In this study, the synthesis of smart, polymerically embedded titanium dioxide (TiO) nanoparticles aimed to exhibit photo-induced anticancer properties under visible light irradiation is investigated. The TiO nanoparticles were prepared by utilizing the sol gel method with different dopants, including nitrogen (N-doped), iron (Fe-doped), and nitrogen and iron (Fe,N-doped). The dopants were embedded in an interpenetrating (IP) network microgel synthesized by stimuli responsive poly (N-Isopropylacrylamide-co-polyacrylicacid)-pNipam-co-PAA forming composite particles.
