“…Under the neutral physiological condition of pH 7.4, BSA molecule (isoelectric pH 4.5-4.7) undergoes a neutral-acidic transition and becomes negatively charged [32]. The negative carboxyl group (-COO) allows attractive electrostatic interaction with positively charged cations, such as Mg 2+ , Ca 2+ [54][55][56]. This finding has been used to explain the adsorption of BSA on the CoCrMo [27], Ti6Al4V [56,57], stainless steel [58], and magnesium alloy [59].…”

Zinc (Zn) and its alloys have received increasing attention as new alternative biodegradable metals. However, consensus has not been reached on the corrosion behaviour of Zn. As cardiovascular artery stent material, Zn is supposed to contact with plasma that contains inorganic salts and organic components. Protein is one of the most important constitute in the plasma and could adsorb on the material surface. In this paper, bovine serum albumin (BSA) was used as a typical protein. Influences of BSA on pure Zn corrosion in phosphate buffered saline is investigated as a function of BSA concentrations and immersion durations by electrochemical techniques and surface analysis. Results showed that pure Zn corrosion was progressively accelerated with BSA concentrations (ranging from 0.05 to 5 g L−1) at 0.5 h. With time evolves, formation of phosphates as corrosion product was delayed by BSA adsorption, especially at concentration of 2 g L−1. Within 48 h, the corrosion of pure Zn was alleviated by BSA at concentration of 0.1 g L−1, whereas the corrosion was enhanced after 168 h. Addition of 2 g L−1 BSA has opposite influence on the pure Zn corrosion. Furthermore, schematic corrosion behaviour at protein/Zn interfaces was proposed. This work encourages us to think more about the influence of protein on the material corrosion and helps us to better understand the corrosion behaviour of pure Zn.

“…The improvement of the hydrophilia would be much easier for the adsorption of biomacromolecules that lead to the improvement of adhesion. An early study showed that fibronectin would be adsorbed to BSA hydrogels due to the exposure of the BSA binding sites in our acidic medium induces a change in the protein’s surface charge, which facilitates protein adsorption [ 7 ]. The adhesion rate of stem cells would be improved with the improvement of the roughness of the surface.…”

“…Albumin hydrogel can act as coating of implants. For example, Sarah et al prepared coating of bovine serum albumin (BSA) on titanium based implant through electrophoretic deposition [ 7 ]. Their results showed that BSA layer could act as an intermediary in interaction with cells, thus leading to enhanced cell adhesion and proliferization.…”

Polyetheretherketone (PEEK) is an important material applied in orthopedic applications, as it posses favorable properties for orthopedic implants, e.g., radiolucency and suitable elastic modulus. However, PEEK exhibits insufficient osteogenesis and osteointegration that limits its clinical applications. In this study, we aimed to enhance the osteogenisis of PEEK by using a surface coating approach. Nanocomposite coating composed of albumin/lithium containing bioactive glass nanospheres was fabricated on PEEK through dip-coating method. The presence of nanocomposite coating on PEEK was confirmed by SEM, FTIR, and XRD techniques. Nanocomposite coatings significantly enhanced hydrophilicity and roughness of PEEK. The nanocomposite coatings also enhanced adhesion, proliferation, and osteogenic differentiation of bone mesenchymal stem cells due to the presence of bioactive glass nanospheres and the BSA substrate film. The results indicate the great potential of the nanocomposite coating in enhancing osteogenesis and osteointegration of PEEK implants.

“…Conventional EPD method uses continuous direct current (DC) as source voltage to deposit film on conductive substrates. Recent studies show innovations in EPD method using modulated current such as pulsed-EPD to prepare collagen membranes [8], NGr-Co 3 O 4 [9] and AC-EPD to prepare TiO 2 [6], hydroxyapatite on titanium [10], BaTiO 3 [11] and bovine serum albumin coatings [12]. The pulsed DC-EPD has been demonstrated to control bubbles incorporation throughout the deposition process [13].…”

An electroactive supercapacitor electrodes have been prepared through deposition of multi walled carbon nanotubes-polypyrrole (MWCNTs-PPy) via alternating current electrophoretic deposition method (AC-EPD). Using safranin (SAF) as co-dispersant, a stable and well-dispersed MWCNTs were obtained and the deposits of MWCNTs-PPy were successfully formed using AC peak to peak voltage of 8V but at difference frequencies of 0.01 Hz, 4 Hz and 250 Hz. Varying the frequencies of the applied voltage has been found influencing the morphology and electrochemical properties of the deposited films. A more porous and highest deposited mass of 0.021 g was obtained at frequency of 4 Hz, while at 250 Hz the deposited mass reduces to 0.017 g. The lowest deposited mass of 0.015 g was obtained at the lowest frequency (0.01 Hz). In addition, the morphology structure of the composite film at 4 Hz shows that the PPy were well-distributed throughout MWCNTs surface. The XRD result shows the presence of amorphous PPy and graphite-like MWCNTs for all deposited samples. It has been shown that the specific capacitance values for the composites also strongly depends on the frequency of applied voltage. In the case of frequency of 4 Hz, higher values can be found at 76.08 F g −1 which was more than two folds increment from the lowest frequency (0.01 Hz), however at the highest frequency (250 Hz) a specific capacitance values of 65.03 F g −1 have been measured. The AC-EPD provides avenue for depositing nanocomposites film at relatively low apllied voltage however, there have no linear correllations been observed on the morphology and electrochemical properties of the deposited films as the frequencies of applied voltage increases.
