Anti‐biofilm formation on the surface is a severe issue in medical implants, hull surface, and food industry. Antimicrobial peptide, magainin II, was covalently bound to stainless steel surfaces through multi‐step modification. The untreated and modified samples were analyzed by SEM‐EDS, XPS, and contact angle, respectively, which indicated the peptide was immobilized on the surfaces. The antimicrobial tests of modified samples were conducted using Staphylococcus aureus and Escherichia coli, and the results revealed that peptide modified surface decreased the biofilm and bacteria quantity of stainless steel surface.

“…A well-established fabrication approach for preparing antibacterial surfaces includes the chemical functionalization of the surface using antibiotics (44), heavy metals (45), quaternary-ammonium compounds (46), fluorine (47), phenols (48,49), or iodine (50) implanted into a durable coating. However, these surface coatings release their compounds gradually over time and do not kill bacteria by direct contact.…”

The mechano-bactericidal activity of nanostructured surfaces has become the focus of intensive research toward the development of a new generation of antibacterial surfaces, particularly in the current era of emerging antibiotic resistance. This work demonstrates the effects of an incremental increase of nanopillar height on nanostructure-induced bacterial cell death. We propose that the mechanical lysis of bacterial cells can be influenced by the degree of elasticity and clustering of highly ordered silicon nanopillar arrays. Herein, silicon nanopillar arrays with diameter 35 nm, periodicity 90 nm and increasing heights of 220, 360, and 420 nm were fabricated using deep UV immersion lithography. Nanoarrays of 360-nm-height pillars exhibited the highest degree of bactericidal activity toward both Gram stain-negativePseudomonas aeruginosaand Gram stain-positiveStaphylococcus aureusbacteria, inducing 95 ± 5% and 83 ± 12% cell death, respectively. At heights of 360 nm, increased nanopillar elasticity contributes to the onset of pillar deformation in response to bacterial adhesion to the surface. Theoretical analyses of pillar elasticity confirm that deflection, deformation force, and mechanical energies are more significant for the substrata possessing more flexible pillars. Increased storage and release of mechanical energy may explain the enhanced bactericidal action of these nanopillar arrays toward bacterial cells contacting the surface; however, with further increase of nanopillar height (420 nm), the forces (and tensions) can be partially compensated by irreversible interpillar adhesion that reduces their bactericidal effect. These findings can be used to inform the design of next-generation mechano-responsive surfaces with tuneable bactericidal characteristics for antimicrobial surface technologies.

“…The contact angle was measured within 10 s of placing the drop (3 μL) on the surfaces and an average of six measurements was reported. The approach of Good, Van Oss, and Chaudhury (acid–base theory) was used to calculate the surface free energy as previously reported . The surface energy parameters of the acid–base component of the probe liquids were previously described …”

Poly(ethylene terephthalate) (PET) is a semiaromatic thermoplastic polyester used in many fields. For specific applications, controlled of the surface wettability (hydrophily/hydrophoby) could be a great challenge. Aminolysis of PET surfaces with branched polyethylenimine gives amino functional groups on the surface with high grafting density. Then, in a second step, atom transfer radical polymerization (ATRP) initiator was grafted by reaction with 2-bromoisobutyryl bromide. Surface initiated ATRP of 2-lactobionamidoethyl methacrylate (LAMA) was performed in solution in the presence of a sacrificial initiator or an appropriate amount of Cu(II) species that act as deactivator. The efficiency of all reactions was confirmed by X-ray photoelectron spectroscopy. Wetting properties and surface energy were found to vary systematically depending to the type of functionalization and grafting. The quantity of grafted carbohydrate was determined by phenol/sulfuric acid colorimetric titration. The sugar graft density was observed to vary according to the ratio (monomer)/(free initiator). High graft density could be obtained yielding to superhydrophilic polymer brushes.
