The gold nanoparticles surface was modified by thioglycolic acid ligand and their surface was coated by the chitosan-grafted-poly(N-vinylcaprolactam) (chitosan-g-PNVCL) copolymer. The cisplatin anticancer drug was loaded into the synthesized nanocarriers and its performance was investigated for the treatment of MCF-7 breast cancer cells in vitro. The synthesized nanoparticles were characterized using FTIR, DLS, TEM, SEM, EDX and TGA analysis.
View Article and Find Full Text PDFA new chelating resin was prepared by coupling Amberlite XAD-2 with Brilliant Green through an azo spacer. The resulting resin has been characterized by FTIR spectrometry, elemental analysis, and thermogravimetric analysis and studied for the preconcentration and determination of trace Pb(II) ions from solution samples. The anionic complex of Pb(II) and iodide was retained on the resin by the formation of an ion associate with Brilliant Green on Amberlite XAD-2 in weak acidic medium.
View Article and Find Full Text PDFA new chelating resin is prepared by coupling Amberlite XAD-4 (Serva, Heidelberg, New York) with m-phenylendiamine through an azo spacer, characterized (by elemental analysis, infrared, and thermogravimetric analysis) and studied for preconcentrating nickel(II), cobalt(II), zinc(II), copper(II), and chromium(III) using flame atomic absorption spectrometry for metal monitoring. The optimum pH values for sorption of the above-mentioned metal ions were 8.5, 8.
