Green Synthesis of Engineered CdS Nanoparticles with Reduced Cytotoxicity for Enhanced Bioimaging Application

Abstract

The modern epoch of semiconductor nanotechnology focuses on its application in biology, especially in medical sciences, to fetch direct benefits to human life. Fabrication of devices for biosensing and bioimaging is a vibrant research topic nowadays. Luminescent quantum dots are the best option to move with, but most of them are toxic to living organisms and hence cannot be utilized for biological applications. Recent publications demonstrate that surface treatment on the nanoparticles leads to enhanced luminescence properties with a drastic reduction in toxicity. The current work introduces surface-modified CdS, prepared via a simple green chemical route with different medicinal leaf extracts as the reaction media. Lower toxicity and multiple emissions in the visible region, observed for the CdS-O.tenuiflorum hybrid structures, make them a better option for future biological applications. Furthermore, the hybrid structure showed enhanced electrical properties, which promises its use in modifying the current optoelectronic devices.

Green synthesis of CdS:Sn NPs by Starch as a Covering Agent and Studying its Physical Properties

“…1 and Table . 1, that the grain size vertical to the substrate is growing while the crystal size parallel to the surface is shrinking. The former correlates to the (002) crystalline orientation, whereas the latter corresponds to the (001) crystalline orientation consistent with Naranthatta et al 21 .…”

Mesoporous Co3O4@CdS nanorods as anode for high-performance lithium ion batteries with improved lithium storage capacity and cycle life

“…19 With the close observation, a slight shi was also observed in the position of 1LO and 2LO modes which is due to the shape of the nanostructures. 20 In addition, the composite spectrum exhibits broadening associated with the slight changes in the crystalline structure of pristine Co 3 O 4 as mentioned by previous reports. 21 To examine the morphology of the as-prepared Co 3 O 4 @CdS structure, SEM was performed.…”
