Preparation of Barbed ZnO Fibers and the Selective Adsorption Behavior for BSA

Abstract

ZnO electrospun nanofibers can act as seed fibers to fabricate multidentate barbed fibers perpendicular to the growth of the fibers using the chemical bath deposition (CBD) method. Fibers with a multirod morphology have a porous grid structure. The sample is easy to recover, and the nonpolar surface in the sample is sufficiently exposed. In the research of barbed fiber fabrication and adsorption on bovine serum albumin (BSA), the effects of different chemical bath conditions on the growth of ZnO nanorods were discussed. Barbed fibers with large slenderness ratios were obtained at a water content of 60 mL at 75 °C. Each milligram of barbed fibers can quickly adsorb about 162 μg of protein within 30 min. The adsorption activity of BSA between polar and nonpolar ZnO surfaces was also studied. The selective adsorption behavior of BSA on the nonpolar surface was revealed.

Controlling the Binding Efficiency of Surface Confined Antibodies through the Design of Mixed Self‐Assembled Monolayers

“…This is mainly due to the high hydrophilicity of the OH‐terminated SAM, which generally implies lower albumin adsorption compared to COOH‐terminated SAMs. [ 40–42 ] Thus, the compact layer of NMPA molecules of this mixed SAM could, indeed, prevent albumins from physisorption as suggested by the SPR characterization.…”

Decreasing free fatty acid of crude palm oil with polyvinylidene fluoride hollow fiber membranes using a combination of chitosan and glutaraldehyde

“…As a result, the increased hydrophobicity of the PVDF/CS 0.5 surface promoted BSA adsorption, as indicated by the fact that BSA is mostly adsorbed on the nonpolar surface. 44 Hollow ber membrane performance…”

Adsorption characteristics of bovine serum albumin onto α-Fe2O3 nanoparticles prepared via the alcohol solution combustion process of ferric nitrate

“…In this project, we prepared magnetic α-Fe 2 O 3 nanoparticles via the ethanol solution of iron nitrate combustion-calcination process, which would provide research basis for the construction of drug delivery system in living organisms; and with bovine serum albumin (BSA) [37] as the model of biological macromolecule due to its representativeness, low price and easy purification [38,39], the adsorption capacity and mechanism of BSA onto α-Fe 2 O 3 nanoparticles were revealed.…”
