“…Previously, a triphenyl phosphonium-possessing homopolymer derived via ROMP was shown to have antibacterial properties in solution as well as on a solid surface [31,39]. Hexylpyridinium bearing polymers were also proved to feature antibacterial properties on a glass surface [31,43]. From these previous studies we have obtained, if we can make copolymer series containing these functional groups, we can obtain a biocidal effective copolymer series similarly.…”

“…For example, a sensor surface coated with alternating by layers of oppositely charged polyelectrolytes (polyethyleneimine (PEI) and poly(sodium 4-styrenesulfonate) (PSS)) showed a detection limit as low as 10 1 cfu/mL for E.coli with a response time of around 20 min [29]. Previously we observed that a pyridinium and phosphonium-bearing ROMP type polymer showed biocidal activity on a solid surface [30,31]. We think an electrode surface covered with a biocidal ROMP-type polymer could be used as a bacteria sensor.…”

There is growing interest in the detection of bacteria in consumables, for example, in the food and water sectors. In this study, the aim was to produce a polymer-based bacteria biosensor via ROMP (ring opening metathesis polymerization). In the first part of the study, block and random copolymers were synthesized, and their biocidal activities were tested on the glass surface. Interdigitated electrode arrays coated with the polymers possessing the highest activity were used to screen the affinity towards different bacterial strains by monitoring impedance variations in real-time. The polymer-coated electrode could detect gram-positive and gram-negative bacteria strains at a concentration of 10 7 cfu/mL. The results show that ROMP-based polymer offers bacterial detection and can be used in developing biosensor devices for efficiently detecting pathogenic bacteria.

“…In this study two classic bacteria, Gram-positive Staphylococcus aureus (S.aureus, ATCC25923), and Gram-negative Escherichia coli (E.coli, ATCC25922) were used to investigate bactericidal activity. The antimicrobial tests were performed using the modified American Standard ASTM E2149-01 method (15), in which samples are stirred constantly in bacterial suspension and thus, ensure good contact between the sample and the bacteria (16). S.aureus and E.coli were incubated at 37°C overnight, and preserved on nutrient plates.…”

45S5 bioactive glasses (BGs) are special class of glasses that form chemical bonds with surrounding bone tissue, which is due to the dissolution behavior of these glass materials. Furthermore, BG shows an antibacterial effect since the dissolution of BG results with high aqueous pH that affect bacterial viability. In this study, the antibacterial activity of Al2O3 doped bioactive glasses (AGs) was evaluated. AGs were produced via the melt quenching method. Functional groups of glasses were evaluated with Fourier Transform Infrared (FTIR) analysis, and glassy structure was evaluated by X-ray diffraction (XRD). Specific surface area, particle size information, and density of milled BG and AGs were obtained using surface area and porosity instrument, laser scattering particle size distribution analyzer and He pycnometer, respectively. Antibacterial activity of bioactive glasses was investigated on Staphylococcus aureus and Escherichia coli via Standard Colony Count Method at 50 mg/mL concentration and different time points, pH change of the media in the presence of BG and AGs at 50 mg/mL concentration was also measured at identical time points. XRD analysis revealed amorphous structure of BG and AGs. Similar specific surface area, particle size and density values were obtained for BG and produced AGs. Antibacterial test results showed that Al2O3 doped 45S5 bioactive glasses had decreased antibacterial activity compared to 45S5 bioactive glass for both bacteria studied.
