“…[8][9][10] Other common antibacterial agent, such as quaternary ammonium salts containing with alkyl chain are widely used in antibacterial applications since the cationic charges in the structures attract cell membrane surface through ionic interaction, then disrupt the structure of cellular membranes resulting in the leakage of intracellular components and consequent cell death. [11][12][13] To bond the antibacterial agents to surfaces of devices, various methods have been reported, such as chemical graing, 14 layer-by-layer assembly deposition 15 or surface polymerization. 16,17 In general, the strategies are developing methacrylate monomers with pendant bactericide moieties which are subsequently polymerized or copolymerized with other monomers.…”

Most materials for bone tissue engineering are in form of highly porous open-celled components (porosity >70%) developed by means of an adequate coupling of formulations and manufacturing technologies. This paper is dedicated to porous components from BGMS10 bioactive glass, originally designed to undergo viscous flow sintering without crystallization, which is generally known to degrade the bioactivity of 45S5 bioglass. The adopted manufacturing technologies were specifically conceived to avoid any contamination and give excellent control on the microstructures by simple operations. More precisely, ‘green’ components were obtained by digital light processing and direct foaming of glass powders suspended in a photosensitive organic binder or in an aqueous solution, activated with an organic base, respectively. Owing to characteristic quite large sintering window of BGMS10 glass, sintering at 750 °C caused the consolidation of the structures generated at room temperature, without any evidence of viscous collapse.

Polymer fibres are widely used in various materials in contact with the human body. As bacterial contamination may lead to the emergence of disease, it is necessary to provide fibres with durably antibacterial properties. In this work, based on 4-vinyl pyridine, fluorine-containing monomers and acrylic acid monomers, new quaternary ammonium salt polymer containing fluorine (NP) were prepared by solution polymerisation, and then the antibacterial composite fibre was prepared by melt spinning of the NP (9 wt%) and Nylon 6 fibre (PA6). The structure and properties of NP and composite fibres were characterised, respectively. The results indicated that the water contact angle of NP reached 104°, the pyrolysis temperature was 302°C, and the interface interaction between NP and PA6 was good, which could achieve more uniform dispersion in Nylon 6 matrix. In addition, the composite fibre decreased obviously the number of colony-forming units within 24 h (the bactericidal rate was 99.99% against E. coli and 99.81% against S. aureus) compared with pure PA6 fibre. The composite fibre was a good durably antibacterial material, which could still inactivate over 96% inoculated E. coli and S. aureus after washing 7 days.
