Navya P.N., Daima H.K., Siddaganga Institute of Technology, IN

Innovative approaches to engineer nanoparticles with desired physicochemical characteristics open new opportunities to utilise such materials for assorted applications. In this context, various methods have been developed to prepare metal nanoparticles. However, most of the [...]

Amino acids-conjugated gold, silver and their alloy nanoparticles: Role of surface chemistry and metal composition on peroxidase like activity

Daima H.K., Selvakannan PR., Bhargava S.K., Shastry S.K., Bansal V., Siddaganga Institute of Technology, IN

New strategies to fabricate nanomaterials of desired physicochemical properties open up new avenues to use nanomaterials for diverse biological applications. In this context, we demonstrate a green and single step synthesis method to obtain monometallic [...]

Self Assembled Nanostructures of Triblock Co-polymer and Plasmid DNA for Gene Delivery

Daima H.K., Shankar P.R. Selvakannan S., Bhargava S.K., Bansal V., RMIT University, AU

In present work, we have used tri-block copolymer (PEO-PPO-PEO) as a non-viral vector to deliver plasmid DNA (pDNA). Green fluorescence protein (GFP) plasmid DNA was used as a model plasmid DNA. Addition of pDNA to [...]

Sequential Surface Functionalization by Polyoxometalates and Lysine Renders Non-toxic Gold Nanoparticles Strong Antibacterial Agents

Daima H.K., Selvakannan P.R., Bhargava S.K., Bansal V., RMIT University, AU

Gold nanoparticles (AuNPs)are considered as biocompatible and important component for biomedical applications. In current study, AuNPs were synthesised using tyrosine amino acid mediated reduction of gold ions. These nanoparticles were functionalised with two polyoxometalates (POMs) [...]
