“…Biofouling significantly shortens the lifespan of materials in contact with biological fluids. For example, in the biomedical sector, devices such as biosensors will produce false signals when covered in proteins and filtration membranes are known to suffer, as biomolecular adhesion causes blockage of the membrane, thus preventing flow through the device [1,2]. Bio-fluids, and in particular proteins, cause this fouling phenomenon because they are charged particles that are amphiphilic and amphoteric, and therefore adsorb easily to most materials [3].…”

Simple Coatings to Render Polystyrene Protein Resistant

Non-specific protein adsorption is detrimental to the performance of many biomedical devices. Polystyrene is a commonly used material in devices and thin films. Simple reliable surface modification of polystyrene to render it protein resistant is desired in particular for device fabrication and orthogonal functionalisation schemes. This report details modifications carried out on a polystyrene surface to prevent protein adsorption. The trialed surfaces included Pluronic F127 and PLL-g-PEG, adsorbed on polystyrene, using a polydopamine-assisted approach. Quartz crystal microbalance with dissipation (QCM-D) results showed only short-term anti-fouling success of the polystyrene surface modified with F127, and the subsequent failure of the polydopamine intermediary layer in improving its stability. In stark contrast, QCM-D analysis proved the success of the polydopamine assisted PLL-g-PEG coating in preventing bovine serum albumin adsorption. This modified surface is equally as protein-rejecting after 24 h in buffer, and thus a promising simple coating for long term protein rejection of polystyrene.

“…The membrane surfaces were then modified by dipping myoglobin solution at different pH values (5.0, 7.0, 9.0, and 11.0) and concentrations (30, 50, and 70 mg/L). Myoglobin (protein) was selected as the coating agent as the membrane surfaces functionalized with amine groups will be more resistant to protein accumulation, thus preventing the fouling [5]. The membranes were then rinsed using phosphate buffer and pressed softly using tissue for few minutes to allow the removal of excessive myoglobin solution from the membrane surface.…”

“…So far, there are a few reports devoted to the effect of film surface morphology, hydrophobicity, and quaternary ammonium component on the variation in antibacterial behaviour [21,24]. For instance, Hatakeyama et al found that the polymer-containing quaternary ammonium groups possess superb antiadhesion for BSA proteins [25]. It is a pity that the investigation has not been thoroughly discussed.…”

Engineered Multifunctional Fluorinated Film Based on Semicontinuous Emulsion Polymerization Using Polymerizable Quaternary Ammonium Emulsifiers

Along with society's progress, high-quality coatings are widely used. Although fluorinated polymers were successfully prepared by semicontinuous emulsion polymerization with surfactants, chlorotrifluoroethylene (CTFE), and acrylate monomers, the optimization collocation of surfactants still has room for improvement. The traditional emulsifiers are physically absorbed onto the surface of latex particles. The latex film generated by latex particles is unstable in water, which limits its application. Herein, a novel series of cationic quaternary ammonium polymerizable surfactant was selected because it can react with CTFE and acrylate monomers and can become a part of the polymers. We also studied the effects of emulsifier type on resultant emulsion properties. In addition, wonderful weatherability, water resistance, and antibacterial and antifouling of the multifunctional fluorinated films were observed, which would open up a bright future for coating industries.
