LSNR:GO template for BSA interaction, photo and sonocatalytic reductions of fluorescent dyes in aqueous solutions

Abstract

Lanthanide sulfide nanorods (LSNR) were synthesized on fusing sodium (Na) metal with hexahydrate chloride salts of lanthanum (La), cerium (Ce), terbium (Tb), and holmium (Ho) (Ln〖Cl〗_3.〖6H〗_2 O) having 〖4f〗^0, 〖4f〗^1,...

Selenium‐doped albumin nanoparticles enhance tamoxifen‐induced anticancer effects in 4T‐1 mouse breast cancer cells

“…The specific absorption peaks observed in the BSA spectra at 1680 and 1500 cm −1 were assigned to amide‐I (C=O stretching vibrations) and amide‐II (N–H bending vibrations), respectively 27 . In the FT‐IR spectra of Se NPs, a distinct absorption peak at 3400.91 cm −1 indicated the binding of Se ions with hydroxyl and/or amine groups in BSA 28 . Notably, the stretching vibration of hydrocarbon (C=C) bonded alkenes was observed around 1620.75 cm −1 , whereas the prominent peak at 1655.33 cm −1 reflected the involvement of the amide‐I bond (–C=O) of albumin in capping and stabilizing the Se NPs 29 .…”

“…27 In the FT-IR spectra of Se NPs, a distinct absorption peak at 3400.91 cm À1 indicated the binding of Se ions with hydroxyl and/or amine groups in BSA. 28 Notably, the stretching vibration of hydrocarbon (C=C) bonded alkenes was observed around 1620.75 cm À1 , whereas the prominent peak at 1655.33 cm À1 reflected the involvement of the amide-I bond (-C=O) of albumin in capping and stabilizing the Se NPs. 29 Moreover, the bands at 1680 and 1500 cm À1 in albumin, corresponding to amide-I and amide-II vibrations, respectively, were observed to shift towards lower wavenumbers in the Se NPs spectra, suggesting the attachment of Se NPs to albumin through the amine groups.…”
