Effective Potentiality of Synthesised CdS Nanoparticles in Inducing Genetic Variation on Macrotyloma uniflorum (Lam.) Verdc.

Effectivity of copper and cadmium sulphide nanoparticles in mitotic and meiotic cells of Nigella sativa L. (black cumin) – can nanoparticles act as mutagenic agents?

“…Verdc. [11,12] Occurrence of seedless plants at M 1 in all the treated materials and more so in Cu-and CdS-NPs is rather significant. Seed formation is a result of cumulative effects of many important processes like sporogenesis, pollination, fertilisation and embryogeny.…”

“…Cu-and CdS-NPs were prepared using wet chemical co-precipitation methods as adopted earlier by Chatterjee et al [51] and Halder et al, [11] respectively. Cu-NPs was prepared using 8 ml (10%, w/v) gelatin (Merck, India), 0.5 ml of 0.1 M CuCl 2 (SRL, India) and 1.5 ml Milli-Q water (0.22 m, Millpore membrane), and the ingredients were thoroughly mixed.…”

“…Effect on meiotic cells of plant species are expected to bring about genetical changes. Halder et al [11,12] reported that copper (Cu) and cadmium sulphide (CdS) NPs induce stable and heritable phenotypic changes in Macrotyloma uniflorum (Lam.) Verdc (Family: Leguminosae).…”

Nanoparticle (CdS) interaction with host (Sesamum indicumL.) – its localization, transportation, stress induction and genotoxicity

“…CdS-NPs were synthesized following the wet-chemical coprecipitation technique adopted earlier by Halder et al (2015b). For the purpose, cadmium acetate dihydrate [(CH 3-COO) 2 Cd·2H 2 O; 0.01 M, 4 mL] and sodium sulfide [Na 2 S; 0.01 M, 4 mL] reaction kinetics was regulated within sodium dodecyl sulfate (SDS; 10.0%, 50 mL) capping environment under vigorous stirring.…”

“…Nanomaterials are the specialized nanodimensional class (at least one dimension <100 nm) of crystalline structures possessing high surface to volume ratio rendering unique optophysical, chemo-reactive and catalytic properties in the nanoscale region. Nanoparticle (NP)-mediated research is a promising multidisciplinary field enduring next generation potentiality due to its wide array of application in electronics (Delgado-Ramos 2014), photonics, cosmetics, energetics (Zhou et al 2014), medicine, biotechnology (Al-Halafi 2014), agriculture (Halder et al 2015a(Halder et al , 2015b, among others. However, geometric progression while utilizing the nanomaterials in consumable and manufactured products results in their indiscriminate release in eco-environmental inter-collegium mostly through industrial wastewater and various anthropogenic activities (Pillai et al 2016), leading to environmental pollution (Nowack and Bucheli 2007).…”
