The antibacterial activities, cytotoxicity, and wound healing of amine(3-aminopropyltriethoxysilane (APTES))-functionalised zeolite Y against normal human fibroblast cells were studied. The characterisation of unmodified and amine-functionalised zeolites Y (Z, ZA 0.04, ZA 0.4, and ZA 0.6) by Fourier transform infrared spectroscopy, X-ray powder diffraction, and energy dispersive X-ray analysis proved that the APTES molecules were grafted onto the zeolite Y surface without distorting its framework structure. All amine-functionalised zeolite Y samples possessed antibacterial activities against several ATCC bacteria that were correlated with the increased amount of APTES on the zeolite Y surface. Conversely, when a higher concentration of APTES was grafted on the zeolite Y, higher cytotoxicity was observed against the fibroblast cells. Although the ZA 0.6 sample (zeolite Y functionalised with 0.6 M of APTES) had …
