Microwave Assisted Biosynthesis of Cadmium Nanoparticles: Characterization, Antioxidant and Cytotoxicity Studies

Cytotoxicity and anti-biofilm activities of biogenic cadmium nanoparticles and cadmium nitrate: a preliminary study

“…It has been proposed that metal ions are reduced by secondary metabolites, including avonoids, alkaloids, polyphenols, polysaccharides, as well as proteins, amino acids, enzymes, and vitamins present in the plant parts. One proposed mechanism of NPs synthesis is the reduction of metal ions by secondary metabolites, such as avonoids, alkaloids, polyphenols, polysaccharides, proteins, enzymes, and vitamins present in the plant parts (Sahoo et al 2021;Shakibaie et al 2021). A similar endorsement was made during the rapid reduction of Cd chloride using aqueous marigold and rose ower petal extract.…”

“…In a study by Shikabaie et al (Shakibaie et al 2021), Cd NPs and Cd (NO 3 ) 2 were shown to induce a concentration-dependent response in 3T3, MCF-7, A549, U87, and HT-29 cell lines with the IC 50 values of 10.6 µg mL − 1 , 1.8 µg mL − 1 , 47.2 µg mL − 1 , 62.9 µg mL − 1 , and 133.5 µg mL − 1 , respectively. The viability of human erythroleukemia cells (K562 cells) and human embryonic kidney cells (HEK293T cells) was decreased in a dose-and time-dependent manner after treatment with CdTe quantum dots (QDs) at The cytotoxicity effect of other Cd-containing NPs, like spherical CdTe-QDs (14 nm), caused intrinsic and extrinsic apoptosis in HepG2 cells after 6 h, 12 h, and 24 h treatment (0.001-100 µg mL-1).…”

“…The synthesis of Cd NPs followed the same procedure we used in our previous work (Shakibaie et al 2021). Brie y, an aqueous extract of A. persica (0.5% w/v, 100 mL) was mixed with Cd (NO 3 ) 2 solution (7.7 Mm, 10 mL), and the mixture was heated three times (15 s) by a microwave oven (850 W, with 10 min rest intervals).…”

“…The shape of Cd NPs was measured by a scanning electron microscope (SEM) apparatus (KYKY-EM3200). The Zeta sizer Nano S90 (Malvern) analyzed the size distribution pattern of the NPs (Shakibaie et al 2021).…”

“…Cd NPs were synthesized based on our previous procedures (Shakibaie et al 2021). Reduction of aqueous Cd (NO 3 ) 2 ions by A. persica aqueous extract was observed by the opaci cation of the yellowish color of the mixture.…”
