“…avs.scitation.org/journal/bip A number of different surfaces, including glass, [10][11][12] gold, 13-15 PVDF, 16,17 and cellulose membranes, 7,18,19 have been functionalized with zwitterionic polymers to improve fouling resistance. Where surfaces do not directly present reactive surface groups for functionalization, alternate methods are sought to introduce zwitterionic chemistries to the interface.…”

Carboxybetaine functionalized nanosilicas as protein resistant surface coatings

et al. 2020

Materials with protein resistant properties are increasingly sought after for their potential application as low-fouling surface coatings. Hydrophilic coatings with improved resistance to protein fouling have been prepared from zwitterionic carboxybetaine (CB) functionalized silica nanoparticles (SiNPs). The authors report three methods of coating preparation via direct tethering of CB to predeposited particle films, a two-step surface functionalization process, and deposition of CB functionalized particle dispersions. The pH at which aqueous CB solutions were prepared and reacted to SiNPs was found to drastically influence the mechanism of CB attachment and affect the protein resistance of the resultant coatings. Depending on the method of coating preparation, protein binding to functionalized particle coatings was reduced by up to 94% compared to unfunctionalized SiNP control surfaces. As a result, all three methods offer simple and scalable fabrication routes for the generation of hydrophilic, zwitterionic interfaces with improved inhibition to protein fouling.

“…Our group developed a mixed‐charge poly(quaternized vinyl pyridine‐co‐n‐butyl methacrylate‐co‐methacrylate acid) (P(QVP‐co‐nBMAco‐MAA)) coating, which showed resistance to nonspecific adsorption of proteins and therefore improved the hemocompatibility of the surface (Fan et al, ). Venault et al () reported poly(vinylidene fluoride) membranes that modified by the mixed‐charge copolymer of [2‐(methacryloyloxy) ethyl]trimethylammonium and sulfopropylmethacrylate. The mixed‐charge membrane showed efficient resistance to nonspecific protein adsorption and bacteria attachment.…”

Mixed‐charge bionanointerfaces: Opposite charges work in harmony to meet the challenges in biomedical applications

Understanding and regulation of the interfaces formed between materials and biological systems has been considered as one of the major tasks in nanotechnology, as the bionanointerfaces often exert profound effects on the fates and therapeutic outcomes of nanomaterials. In the last decades, materials with mixed‐charge surfaces have witnessed fast development. The oppositely charged units on the materials' surface could work in a charge balanced way or a charge biased way, which offers much more possibilities to the bionanointerfaces than materials with singly charged surface. It has been found out that mixed‐charge residues could bring about functionalities such as antifouling ability, pH‐sensitivity, self‐assemble propensity, thermal sensitivity, and so on. In this review, recent advances in developing mixed‐charge bionanointerfaces would be carefully overviewed and the potential applications and challenges of mixed‐charge materials in biomedical field will be discussed. This article is categorized under: Therapeutic Approaches and Drug Discovery > Emerging Technologies Biology‐Inspired Nanomaterials > Protein and Virus‐Based Structures

Electric responsive membranes have been prepared by controlled surface grafting of poly (ionic liquid) (PIL) on the commercially available regenerated cellulose ultrafiltration membrane. The incorporation of imidazolium ring on membrane surface was evidenced by FTIR (Fourier transformed infra-red) and EDX (energy-dispersive X-ray) spectroscopy. The PIL grafting resultedin a rougher surface, reduction in pore size, and enhancement in hydrophilicity. The interaction of the electric field between the charged PIL brush and the oscillating external electric field leads to micromixing, and hence it is proposed to break the concentration polarization. This micromixing improves the antifouling properties of the responsive membranes. The local perturbation was found to decrease the water flux, while it enhanced protein rejection. At a higher frequency (1kHz) of the applied electric field, the localized heating predominates compared to micromixing. In the case of a lower frequency of the applied electric field, more perturbation can lead to less permeability, whereas it will have a better effect in breaking the concentration polarization. However, during localized heating at a higher frequency, though perturbation is less, a heating induced reduction in permeability was observed. The electric field response of the membrane was found to be reversible in nature, and hence has no memory effect.
