“…Additionally, the authors observed that deposition of only DMLPEI on negatively charged Si wafers lacked any antibacterial activity, confirming the thought that tight binding of the positive surface charges is detrimental for the antibacterial activity of these QACs. Similar results were found in sort-like multilayer system using different QACs [93]. An alternative method to ensure availability of the positive charges of QACs to keep their antimicrobial activity is by covalent immobilization on glass using a short linker molecule.…”

Bacterial adhesion and subsequent biofilm formation on material surfaces represent a serious problem in society from both an economical and health perspective. Surface coating approaches to prevent bacterial adhesion and biofilm formation are of increased importance due to the increasing prevalence of antibiotic resistant bacterial strains. Effective antimicrobial surface coatings can be based on an anti-adhesive principle that prevents bacteria to adhere, or on bactericidal strategies, killing organisms either before or after contact is made with the surface. Many strategies, however, implement a multifunctional approach that incorporates both of these mechanisms. For anti-adhesive strategies, the use of polymer chains, or hydrogels is preferred, although recently a new class of super-hydrophobic surfaces has been described which demonstrate improved anti-adhesive activity. In addition, bacterial killing can be achieved using antimicrobial peptides, antibiotics, chitosan or enzymes directly bound, tethered through spacer-molecules or encased in biodegradable matrices, nanoparticles and quaternary ammonium compounds. Notwithstanding the ubiquitous nature of the problem of microbial colonization of material surfaces, this review focuses on the recent developments in antimicrobial surface coatings with respect to biomaterial implants and devices. In this biomedical arena, to rank the different coating strategies in order of increasing efficacy is impossible, since this depends on the clinical application aimed for and whether expectations are short- or long term. Considering that the era of antibiotics to control infectious biofilms will eventually come to an end, the future for biofilm control on biomaterial implants and devices is likely with surface-associated modifications that are non-antibiotic related.

“…The durability of antimicrobial finishing can be grouped into two categories, temporary and durable (Payne & Kudner, 1996;Tang et al, 2011). Temporary finishing of textiles is easy to achieve, but is also easily washed off (Hong & Sun, 2011;Pinto, McGahan, Steiner, & Priefer, 2011). Durable antimicrobial finishing is generally achieved by the slow-release method, in which the treated fabrics slowly release the antimicrobial agent to inactivate microorganisms (Abdel-Halim, Fouda, Hamdy, Abdel-mohdy, & El-sawy, 2010;Abou-Zeid et al, 2011;Yao, Li, Danny, Gohel, & Chung, 2011).…”

“…Importantly, increasing the number of PHMB coating layers improved the bactericidal function. Alternatively, Pinto et al[78] investigated the use of poly(4-vinylphenol) (PVPh), a negatively charged bactericidal agent as a possible surface active compound. PVPh was used as polyanionic building block in combination with both weak and strong polycations, PAH and PDADMAC respectively.…”
