Deoxyribonucleic acid (DNA) capped silver nanoparticles are exceptional nanomaterials, featuring precise size and shape control enabled by DNA as a capping agent. DNA stabilizes these nanoparticles' role leading to uniform structures for diverse applications. These nanoparticles are excellent in photonics and medical applications, enhancing fluorescence and medical imaging.

- The synthesis of nanoparticles using biotemplates, particularly DNA, allows for the creation of uniform CdS nanoparticles with potential applications in photocatalysis, antibacterial activity, and bioimaging.
- The study reports that DNA-capped CdS nanoparticles demonstrate better photocatalytic performance and antibacterial effects compared to uncapped ones, effectively inhibiting both Gram-positive and Gram-negative bacteria.
- Cytotoxicity tests on HeLa cells show that DNA-capped CdS nanoparticles are biocompatible, with a significant cell viability rate at lower concentrations, suggesting their potential use in medical applications.
In the present work, biocompatible CdS nanoparticles were synthesized using Schiff base ligand, 3-((2-(-(1-(2hydroxyphenyl)ethylidene)amino)ethyl)imino)-2-pentone, by a simple ultrasonic irradiation method. The structural, morphological, and optical properties were studied using XRD, SEM, TEM, UV-visible absorption, and photoluminescence (PL) spectra. The quantum confinement effect of the Schiff base capped CdS nanoparticles was confirmed by using UV-visible and PL spectrum analysis.
