Antibacterial potential of rutin conjugated with thioglycolic acid capped cadmium telluride quantum dots (TGA-CdTe QDs)

Chemical Constituents, Quantitative Analysis and Antioxidant Activities ofEchinacea purpurea(L.) Moench andEchinacea pallida(Nutt.) Nutt.

“…Rutin, a pharmaceutically and medicinally valuable compound, existed in methanol and water extracts of both plant species. Recent work about the rutin indicated that it has antioxidant (Das et al 2015), antibacterial (Ananth et al 2015), antidiabetic (Wang et al 2015), anticancer (Arinc et al 2015), antiepileptic (Dubey et al 2015), antimalarial (Choudhary et al 2014) and antithyroid (Panda and Kar 2014) properties. The water extract of E. purpurea leaves, E. purpurea flowers, E. pallida leaves and E. pallida flowers revealed the excellent ABTS cation radical (Fig.…”

Optical and structural properties of hydrophilic CdTe quantum dots in cationic starch polymeric matrix

“…Cadmium–telluride (CdTe) based QDs are fluorescent semiconductor nanoparticles approximately 2–10 nm in diameter, with unique photophysical properties, such as narrow and size‐dependent fluorescence, broad absorption spectra, strong fluorescence intensity, and excellent anti‐photobleaching . CdTe QDs are rapidly being applied in many fields, such as solar cells, light‐emitting devices, biological and medical imaging, drug testing, virus detection, and so on .…”

An integrated study on antimicrobial activity and ecotoxicity of quantum dots and quantum dots coated with the antimicrobial peptide indolicidin

“…The different antibacterial activity has been attributed to the differences in membrane organization and overall molecular composition of the bacterial cell wall and as a consequence of the direct interaction bacteria with the NPs. 58 Gram-positive and Gram-negative bacteria are both characterized by an overall negative charge due to the presence of teichoic acids in the former and lipopolysaccharides in the outer membrane of the latter. There was no major difference between bactericidal and inhibitory concentrations of the QDs and QDs-Ind.…”
