“…Along these lines a functional polymer brush coating has been proposed. This model is composed of an anti-adhesive molecule that repels bacteria, an antimicrobial peptide that kills bacterial upon contact, and a substance containing arginine-glycine-aspartate that enhances tissue integration [71]. Several other technologies for multifunctional surfaces have been proposed and tested [107,255,256].…”

It is expected that the projected increased usage of implantable devices in medicine will result in a natural rise in the number of infections related to these cases. Some patients are unable to autonomously prevent formation of biofilm on implant surfaces. Suppression of the local peri-implant immune response is an important contributory factor. Substantial avascular scar tissue encountered during revision joint replacement surgery places these cases at an especially high risk of periprosthetic joint infection. A critical pathogenic event in the process of biofilm formation is bacterial adhesion. Prevention of biomaterial-associated infections should be concurrently focused on at least two targets: inhibition of biofilm formation and minimizing local immune response suppression. Current knowledge of antimicrobial surface treatments suitable for prevention of prosthetic joint infection is reviewed. Several surface treatment modalities have been proposed. Minimizing bacterial adhesion, biofilm formation inhibition, and bactericidal approaches are discussed. The ultimate anti-infective surface should be “smart” and responsive to even the lowest bacterial load. While research in this field is promising, there appears to be a great discrepancy between proposed and clinically implemented strategies, and there is urgent need for translational science focusing on this topic.

“…In order to avoid biofilmassociated infections, various strategies have been developed to improve the antimicrobial properties of biomaterial surfaces including loading with antibiotics, 31 covalent attachment of AMPs, [14][15][16] and polymer-based surface modification. [32][33][34][35] Although these methods can inhibit bacterial attachment, the procedure is tedious and has a limited efficacy in practice. To overcome these limitations and combat the issues of antibiotic resistance and toxicity, a Ti-binding protein was used to connect the multifunctional chimeric peptides with the Ti surface.…”

BackgroundPrevention of bacterial colonization remains a major challenge in the field of oral implant devices. Chimeric peptides with binding, antimicrobial, and osteogenesis motifs may provide a promising alternative for the inhibition of biofilm formation on titanium (Ti) surfaces.MethodsIn this study, chimeric peptides were designed by connecting an antimicrobial sequence from human β-defensin-3 with a Ti-binding sequence and arginine-glycine-aspartic acid using a glycine-glycine-glycine linker. Binding to the Ti substrate and antimicrobial properties against streptococci were evaluated. Significant improvement in reduction of bacterial colonization onto the Ti surface was observed, with or without the presence of saliva or serum. The MC3T3-E1 cells grew well on the modified Ti surfaces compared with the control group.ResultsThe data showed that the three peptide functional motifs maintained their respective functions, and that the antibiofilm mechanism of the chimeric peptide was via suppression of sspA and sspB gene expression.ConclusionThese results indicated that the endogenous peptide fragments engineered on the Ti surface could provide an environmentally friendly approach for improving the biocompatibility of oral implants.

“…Thermoresponsive poly( N -isopropylacrylamide) (PNIPAAm) brush has been demonstrated to be able to control fibrinogen adhesion according to temperature for the study of the adhesion of human mesenchymal stem cell (hMSC) (21). Block copolymer (Pluronic F-127: PF127) brush conjugated with antimicrobial peptide and RGD peptide can effectively promote the antibacterial property and cell adhesion/spreading in tissue engineering (22). Beyond these studies on the effects of bioactive molecules on stem cells, recent research studies have advanced the modulation of micro-architectures of polymer brush and its properties (23, 24, 30–32).…”

Polymer brush is a soft material unit tethered covalently on the surface of scaffolds. It can induce functional and structural modification of a substrate’s properties. Such surface coating approach has attracted special attentions in the fields of stem cell biology, tissue engineering, and regenerative medicine due to facile fabrication, usability of various polymers, extracellular matrix (ECM)-like structural features, and in vivo stability. Here, we summarized polymer brush-based grafting approaches comparing self-assembled monolayer (SAM)-based coating method, in addition to physico-chemical characterization techniques for surfaces such as wettability, stiffness/elasticity, roughness, and chemical composition that can affect cell adhesion, differentiation, and proliferation. We also reviewed recent advancements in cell biological applications of polymer brushes by focusing on stem cell differentiation and 3D supports/implants for tissue formation. Understanding cell behaviors on polymer brushes in the scale of nanometer length can contribute to systematic understandings of cellular responses at the interface of polymers and scaffolds and their simultaneous effects on cell behaviors for promising platform designs.
