Analysis of conditions for the preparation of BSA/MMT composites

Abstract

This study describes a new method for protein fixation that has high, stable, and good repeatable fixation effect without deactivating protein. This method involves intercalating bovine serum albumin (BSA) into montmorillonite (MMT) under different experimental conditions, i.e., the concentration of coupling agent KH570, pH values, ionic strength, and the impact of buffers. The study showed the interaction of buffer systems with pH values had the most significant influence on adsorption quantity. The existence of the buffer increased the adsorption quantity and helped with slow protein releasing, while the phosphate buffer worked better than acetate buffer. More BSA was adsorbed on KH570 treated than untreated MMT, and among the treated samples the most protein released was on MMT treated with KH570 in 100% ethanol and in the acetate buffer solution. Adsorption quantity of the BSA initially increased and then decreased with the increase of the ionic strength. The research on the preparation of MMT/BSA materials provides further information on the study of protein composites.

Hybrid Films Based on a Bridged Silsesquioxane Doped with Goethite and Montmorillonite Nanoparticles as Sorbents of Wastewater Contaminants

“…In the case of the film doped with Gt ( Figure 5(a) [33,34]. In the case of the film doped with MMT ( Figure 5(b)), only the characteristic peak at 2 = 6.95 ∘ (d 001 = 12.7Å) is observable in the doped SSO film, probably because of the low content of dopant in the material [31,35].…”

Development of Reinforced Structure Designed Composite Pavement

“…During 1940~1945, the United States for the first time using glass fiber reinforced polyester resin to manufacture military radome and aircraft fuel tank by hand lay-up techniques, which was open up a new way for the application of resin matrix composite in industry [1][2]. Up to now, there are many production techniques of resin matrix composite, and it has been formed a complete industrial system from raw materials, forming technology, machinery, and performance testing [3][4][5]. The resin matrix composite breakthrough the limitations of traditional metal materials, and with light weight, high strength and can be easy designed, it has been widely applied in the areas of aerospace, shipping vehicles and bridges, etc [6-7].…”
