Abstract

The idea to use „green” nano-approaches in many fields such as: bioelectronics, biophotonics, or nanomedicine is in the spotlight of scientific world nowadays. This work aimed to highlight novel applications of silver nanoparticles “green” synthesized fromCornus masL. fruits aqueous extract. Dynamic Light Scattering (DLS) resultsrevealed the achieving of AgNPs with a diameter of 41.5 nm. Bio-resulted AgNPs presented moderate physical stability (ZP = -23.25 mV) and demonstrated binding capacity to DNA molecule, fact confirmed by UV-Vis absorption spectroscopy. The strong bathochromic shift of SPR band of cornelian-derived AgNPs could be exploited in DNA biosensing applications. Electrical conductivity measurements revealed theurease inhibitory action of these AgNPs.These findings show that developed nano-bio-silver particles proved to have potential use in biomedical field (urease inhibitor, Drug Delivery Systems design), in biophotonics or in biosensing applications..
