“…The mechanism that PDA layer improves corrosion resistance in this study may be explained as follows: the HF-PDA-treated sample could adsorb more BSA on its surface than HF-treated samples from the corrosion medium because PDA is a good protein immobilizer [71] . And an immobilized BSA layer has been proven to improve the anti-corrosion property of Mg [72] .…”

Surface molecular imprinting, especially on the surface of silica-modified magnetic nanoparticles, has been proposed as a promising strategy for protein recognition and separation. Inspired by the self-polymerization of dopamine, we synthesized a polydopamine-based molecular imprinted film coating on silica-Fe(3)O(4) nanoparticles for recognition and separation of bovine hemoglobin (BHb). Magnetic molecularly imprinted nanoparticles (about 860 nm) possess a core-shell structure. Magnetic molecularly imprinted nanoparticles (MMIP) show a relatively high adsorption capacity (4.65 ± 0.38 mg g(-1)) and excellent selectivity towards BHb with a separation factor of 2.19. MMIP with high saturation magnetization (10.33 emu g(-1)) makes it easy to separate the target protein from solution by an external magnetic field. After three continuous adsorption and elution processes, the adsorption capacity of MMIP remained at 4.30 mg g(-1). Our results suggest that MMIPs are suitable for the removal of high abundance of protein and the enrichment of low abundance of protein in proteomics.

“…Hong et al60 have performed the in vivo study and found that the inflammatory response to poly‐ L ‐lactic acid surfaces was greatly reduced, and the immunological responses of blood on quantum dots were also reduced on the one‐step polydopamine coated samples. Tao et al61 coated dopamine as an ad‐layer for protein immobilization on the diamond‐like carbon (DLC) films, and the survival rate of PC‐12 cells improved by 40% to that of the untreated DLC. Moreover, dopamine was also blended into TiO 2 films and coated on various polymers (namely poly(ethylene terephthalate), poly(tetrafluoroethylene), and polyethylene) to improve cytocompatibility of MC3T3 cells by more than 20%, when compared with the pristine samples 62.…”

Poly(vinylidene fluoride) (PVDF) and polysulfone (PSf) are two polymers with excellent mechanical properties but insufficient biocompatibility mainly due to their surface hydrophobicity. This study has applied oxygen plasma treatments and dopamine coating on the two polymers and investigated the changes of the surface properties and interactions with mammalian cells. All modification steps were verified by means of Electron Spectroscopy for Chemical Analysis and contact angle measurements. Surface topology of materials and biomolecules was studied by atomic force measurements (AFM) and scanning electron microscopy (SEM). Protein adsorption was quantified by fluorescent imaging and Bradford method. The results showed that O(2) plasma altered the surface hydrophilicity effectively on PSf and more than two folds of oxidation were obtained, when compared with the pristine one. The change of surface wettability was less significant on the O(2) plasma treated PVDF due to less oxidation extent, which was identified by analyzing the chemical compositions. The provided functionalized PVDF and PSf surfaces were tested with bovine serum albumin and L-929 mouse fibroblasts to evaluate the effects of surface modifications on protein adsorption and cell attachments. The biocompatibility was effectively promoted to fourfold and twofold on the hydrophobic PVDF and PSf by applying O(2) plasma treatments within short treatment time. Moreover, the simple immobilization of polymers in dopamine solution resulted in hydrophilic surface coating with stability that caused threefold and twofold increases of biocompatibility on PVDF and PSf correspondingly.
