“…Although the competing mechanisms remain unclear, a large body of data suggests that both physical and chemical modifications of a material surface can be engineered to limit bacterial colonization. [5][6][7][8][9][10]12,13,20,22 For example, as shown in Figure 1, coating surgical-grade titanium alloy with a synthetic PEM of PAA and PAH reduced colony density of waterborne S. epidermidis bacteria by orders of magnitude after immersion in 10 7 bacteria/mL. Reduced colonization over both 2 and 4 h incubation timescales is relevant to medical procedure durations involving, for example, cardiac assist and orthopedic implant devices.…”

“…7,[13][14][15] Because biofilm formation requires the initial, stable attachment of a viable bacteria population on a surface, 4 another promising approach to limiting microbial colonization is prevention of bacterial adhesion to material substrata prior to colonization. Others have reported that poly(ethylene glycol)-conjugated polypeptides confer adhesion resistance and suggested that such results may be due to high degrees of substrata surface hydration; 16 this speculation was not systematically tested.…”

Substrata Mechanical Stiffness Can Regulate Adhesion of Viable Bacteria

The competing mechanisms that regulate adhesion of bacteria to surfaces and subsequent biofilm formation remain unclear, though nearly all studies have focused on the role of physical and chemical properties of the material surface. Given the large monetary and health costs of medical-device colonization and hospital-acquired infections due to bacteria, there is considerable interest in better understanding of material properties that can limit bacterial adhesion and viability. Here we employ weak polyelectrolyte multilayer (PEM) thin films comprised of poly(allylamine) hydrochloride (PAH) and poly(acrylic acid) (PAA), assembled over a range of conditions, to explore the physicochemical and mechanical characteristics of material surfaces controlling adhesion of Staphylococcus epidermidis bacteria and subsequent colony growth. Although it is increasingly appreciated that eukaryotic cells possess subcellular structures and biomolecular pathways to sense and respond to local chemomechanical environments, much less is known about mechanoselective adhesion of prokaryotes such as these bacteria. We find that adhesion of viable S. epidermidis correlates positively with the stiffness of these polymeric substrata, independently of the roughness, interaction energy, and charge density of these materials. Quantitatively similar trends observed for wild-type and actin analogue mutant Escherichia coli suggest that these results are not confined to only specific bacterial strains, shapes, or cell envelope types. These results indicate the plausibility of mechanoselective adhesion mechanisms in prokaryotes and suggest that mechanical stiffness of substrata materials represents an additional parameter that can regulate adhesion of and subsequent colonization by viable bacteria.

Background: The characteristics of tissue conditioners support microorganism development that can threaten the health of the dentures user.Purpose: The object of this study was to evaluate the effect on antimicrobial activity, roughness and wettability surface of a tissue conditioners material combined with the antimicrobial polymer poly (2-tert-butilaminoethyl) methacrylate (PTBAEMA). Materials and methods:Specimens of tissue conditioner (Coe Soft ® ) were divided into three groups, according to the concen tration of PTBAEMA incorporated (0, 10 and 25%). Antimicrobial activity was assessed by adherence assay of one of the microorganisms, Staphylococcus aureus, Streptococcus mutans and Candida albicans. Roughness measurements were made using a Mitutoyo SJ-400, and the mean arithmetic roughness values (Ra) obtained were used for the comparisons. The wettability properties were determined by contact angle measurements. Results:The group containing 25% of PTBAEMA inhibited totally the S. aureus and S. mutans biofilm formation. A significant reduc tion in the S. aureus (Kruskal-Wallis, p = 0,001) and S. mutans (Kruscal-Wallis, p = 0,001) count for 10% PTBAEMA group compared with respective control group. No significant difference was found for C. albicans among PTBAEMA groups and control group (ANOVA, p > 0,05). Incorporating 10 and 25% PTBAEMA increased surface roughness and decreased contact angles (ANOVA and Tukey's post hoc tests, α = 5%). Conclusion:Incorporating 10% PTBAEMA into tissue conditioner increases wettability and roughness of tissue conditioner surface; and decreases the adhesion of S. mutans and S. aureus on material surface, but did not exhibit antimicrobial effect against C. albicans. Significance:The PTBAEMA incorporated into tissue conditioner could prevent biofilm formation on elderly patient.

“…Discarded PLA can also be degraded fast [9] and is thus deemed as a good environmentally protective plastic. In addition, poly[2-(tert-butylaminoethyl)methacrylate](TBMA) is a newly invented antimicrobial polymer [10] that is hydrophobic. TBMA is produced via an atom-transfer radical-polymerization (ATRP) [11,12].…”

ABSTRACT This study aims to produce antimicrobial biodegradable composite films. Polylactic acid (PLA) and poly[2-(tert-butylaminoethyl)methacrylate] (TBMA) are combined by using casting molding. The Fourier transform infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC) are used to evaluate the physical properties of the PLA/TBMA composite films. The antimicrobial tests are then used to assess the antibacterial efficacy of PLA/TBMA composite films against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The FT-IR results indicate that the incorporation of TBMA does not influence the chemical structure of the composite films as the composites are a product of physical blending. The DSC results indicate that the incorporation of TBMA causes the crystallization temperature of PLA to increase. Finally, the composite films have proven to be bacteriostatic against S. aureus, and antibacterial against E. coli.
