“…It generally includes positively charged molecules that are theorized to penetrate the cell membrane, disrupt the membrane integrity, and provoke cell lysis. Several types of polymers have been used, including polymers with quaternary ammonium groups,7 guanidine‐containing polymers,8 polymers that mimic natural peptides,9 polymers containing phospho‐10 and sulfo‐derivatives,11 phenol and benzoic acid‐derivative polymers,12 organometallic polymers,13 and more recently polyelectrolyte multilayers 14. An alternative method for disinfecting surfaces consists of using a coating that produces reactive radical species which have no specific target within bacteria upon light activation.…”

The topological transition from order to disorder in crystalline silicon was investigated by a computer simulation procedure. The gradually introduction of topological Wooten–Winer–Weaire defect states makes the crystal change in a more and more disordered assembly of atoms. The characterization of deformation energy around a single defect state is analyzed. The topological transition from graphene structure to an amorphous carbon layer, by introduction of a high number of Stone–Wales defect‐type states was evidenced. The comparison of the disordered structure in tetrahedrally bonded semiconductors (silicon) and a two‐dimensional network based on graphene structure was made.

“…23 Two novel organotin monomers, (N-tri-n-butyltin)maleimide (N-TBTM) and m-acryloylamino-(tri-n-butyltinbenzoate) (m-AATBTB), were copolymerized with styrene in bulk at 65 1C using azobisisobutyronitrile as the free radical initiator to attain the respective antibacterial polymers. 24 The second method is the conjugation of the antimicrobial agent to a pre-formed polymer. For example, 2-benzimidazolecarbamoyl was conjugated to poly(ethylene-covinyl alcohol) (EVOH -CBZ) and, ampicillin was conjugated to poly(styrene-co-maleic anhydride) (PS-MA).…”

Antibacterial non-woven nanofibers of curcumin acrylate oligomers

Two new (meth)acrylate monomers, namely, 4-((1E,6E)-7-(4 0 -hydroxy-3-methoxyphenyl)-3,5-dioxohepta-1,6dienyl)-2-methoxyphenyl acrylate or curcumin monoacrylate (CmA) and 4-((1E,6E)-7-(4 0 -hydroxy-3methoxyphenyl)-3,5-dioxohepta-1,6-dienyl)-2-methoxyphenyl methacrylate or curcumin monomethacrylate (CmMA), are synthesized by reacting (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione (curcumin) with acryloyl chloride and methacryloyl chloride, respectively. The respective derivatives are polymerized by free radical polymerization using an initiator, 2,2-azobisisobutyrontrile (AIBN), to obtain the oligomer of curcumin monoacrylate (OCM) and the oligomer of curcumin monomethacrylate (OCMA). The oligomers are characterized by FTIR, 1 H NMR and UV-vis spectroscopy. The molecular weights of the oligomers are determined by GPC to range between 2000 and 5500 Da. The melting temperature (T m ) and degradation temperature of the respective oligomers are evaluated by thermal analysis. The melting temperature of the oligomers ranged from 195 to 197 1C. Antibacterial studies are evaluated against Staphylococcus aureus, in which the minimum inhibitory concentration (MIC) of OCA1 is 27 mg mL À1 . The blends of the individual oligomers with poly(lactic acid) are electrospun to obtain the respective non-woven nanofiber mats. Nanofibers are formed, with the diameter ranging from 400 to 750 nm, and the nanofiber mats are porous. Because the nanofiber mats are antibacterial and highly porous, they may have potential application as a wound dressing material for tissue regeneration.

“…When positively charged molecules come into contact with bacteria, they can penetrate the cell membrane, disrupt its integrity, and provoke cell lysis. Several other types of polymers have been used: those that mimic natural peptides, , guanidine-containing polymers, , phospho- and sulfo-derivative-containing polymers, − phenol and benzoic acid derivative polymers, , organometallic polymers, polyelectrolyte multilayers, polymers with quaternary ammonium groups, − and zwitterionic polymers such as poly(sulfobetaine methacrylate) or poly(carboxybetaine methacrylate). The latter shows perhaps the greatest promise in the realm of surface-active compounds and has become the most popular synthetic polymer for developing nonbiofouling surfaces.…”

A green photoinduced method for the modification of a biodegradable and biocompatible polymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV), has been successfully carried out using three types of monomers with potential antibacterial effects, i.e., 2-[(methacryloyloxy)-ethyl] trimethylammonium chloride (META), 2-[(methacryloylethyl)]-dimethyl-(3-sulfopropyl) ammonium (MESA) and 2-hydroxyethyl methacrylate (HEMA). The photografting process is conducted through a photoinduced free radical process employing a ketone-based photoinitiator in an aqueous medium. Under appropriate conditions, the photogenerated radicals abstract hydrogen atoms from the PHBHV backbone, thus initiating the UV-mediated photopolymerization of derived-(meth)acrylate monomers from the surface of PHBHV film. The photochemical mechanism of the ketones photolysis is entirely described by a electron spin resonance/spin trapping technique, and the modified-PHBHV films are extensively characterized by ATR-FTIR and water contact angle and XPS measurements. Finally, a primary investigation is conducted to support the antibacterial activity of the new functionalized biomaterial against Escherichia coli and Staphylococcus aureus.
