“…In case of CuInSe 2 /ZnS 1:4 sample (Figures 2c and 4), the main phase (53.8(3) mass. %) is CuInSe 2 with unit cell parameters a = 5.7696 (14) and c = 11.642(5) Å, and microstructural parameters D = 6.4 ± 4.3 nm and ε = 1.80(4)%. Additional phase in this sample is high-temperature ZnS modification preferentially with hexagonal wurtzite structure.…”

“…Recently, several techniques have been successfully developed to synthesize inorganic-coated CuInSe 2 nanomaterials, such as electron beam evaporation [ 10 ], large-scale synthesis using gelatin and thioglycolic acid as dual stabilizers in electric pressure cooker [ 11 ] and organic phase high temperature route combined with alloying [ 12 ]. Stable equi-component CuInSe 2 /ZnS colloidal nanocrystals have been prepared employing different nanostructurization technologies as described in more details elsewhere [ 7 , 8 , 13 , 14 ].…”

The CuInSe2/ZnS multiparticulate nanocomposites were first synthesized employing two-step mechanochemical synthesis. In the first step, tetragonal CuInSe2 crystals prepared from copper, indium and selenium precursors were co-milled with zinc acetate dihydrate and sodium sulfide nonahydrate as precursors for ZnS in different molar ratios by mechanochemical route in a planetary mill. In the second step, the prepared CuInSe2/ZnS nanocrystals were further milled in a circulation mill in sodium dodecyl sulphate (SDS) solution (0.5 wt.%) to stabilize the synthesized nanoparticles. The sodium dodecyl sulphate capped CuInSe2/ZnS 5:0-SDS nanosuspension was shown to be stable for 20 weeks, whereas the CuInSe2/ZnS 4:1-SDS one was stable for about 11 weeks. After sodium dodecyl sulphate capping, unimodal particle size distribution was obtained with particle size medians approaching, respectively, 123 nm and 188 nm for CuInSe2/ZnS 5:0-SDS and CuInSe2/ZnS 4:1-SDS nanocomposites. Successful stabilization of the prepared nanosuspensions due to sodium dodecyl sulphate covering the surface of the nanocomposite particles was confirmed by zeta potential measurements. The prepared CuInSe2/ZnS 5:0-SDS and CuInSe2/ZnS 4:1-SDS nanosuspensions possessed anti-myeloma sensitizing potential assessed by significantly reduced viability of multiple myeloma cell lines, with efficient fluorescence inside viable cells and higher cytotoxic efficacy in CuInSe2/ZnS 4:1-SDS nanosuspension.
