Adsorption of Bovine Serum Albumin onto Hydroxylapatite: Theoretical Modeling and Measurements
Adsorption of Bovine Serum Albumin (BSA) onto calcium Hydroxyl Apatite (HA), Ca10PO4(OH)2, has been studied by Ultra Violet (UV) spectroscopy. The adsorption isotherms of BSA onto the HA surface at 291.7 K and 303.2 K were satisfactorily presented by Langmuir equation and the evaluated parameters are reported. The specific surface area of H...
متن کاملEffects of surface functionalization on the adsorption of human serum albumin onto nanoparticles – a fluorescence correlation spectroscopy study
By using fluorescence correlation spectroscopy (FCS), we have studied the adsorption of human serum albumin (HSA) onto Fe-Pt nanoparticles (NPs, 6 nm radius), CdSe/ZnS quantum dots (QDs, 5 nm radius) and Au and Ag nanoclusters (1-4 nm radius), which are enshrouded by various water-solubilizing surface layers exposing different chemical functional groups (carboxyl, amino and both), thereby endow...
متن کاملSpectroscopic study of ionic liquid adsorption from solution onto gold.
Gold was exposed to ethanol solutions containing 0.1 wt% 1-hexyl-3-methyl-imidazolium bis(trifluoromethanesulfonyl)imide (HMIM NTf2), an ionic liquid (IL). The resulting adsorbed layers were interrogated using X-ray photoelectron spectroscopy (XPS - both conventional and synchrotron-based) and spectroscopic ellipsometry. Ellipsometry indicated that the adsorbed layer thickness was smaller than ...
متن کاملAlbumin (BSA) adsorption onto graphite stepped surfaces.
Nanomaterials are good candidates for the design of novel components with biomedical applications. For example, nano-patterned substrates may be used to immobilize protein molecules in order to integrate them in biosensing units. Here, we perform long MD simulations (up to 200 ns) using an explicit solvent and physiological ion concentrations to characterize the adsorption of bovine serum album...
