Embodiment 1

[0050] NH 2 + Preparation of ion-implanted multi-walled carbon nanotubes:

[0051] Different doses of NH were implanted on pre-sprayed multi-walled carbon nanotube substrates (silicon dioxide) using a BNU 400keV ion implanter 2 + Ions; where NH 2 + The ion flow rate is 2μA; the background vacuum is 1×10 -7 Torr; field current is 2.27A; NH 2 + The implantation energy of the ion beam is 40KeV; by controlling the implantation dose (5×10 14 ions / cm 2 ) to inject NH on MWCNTs 2 + ion, to get NH 2 + Ion-implanted multi-walled carbon nanotubes on silica wafers. The N element content of the prepared material is 0.99%.

Embodiment 2

[0053] NH 2 + Preparation of ion-implanted MWCNTs: BNU 400keV ion implanter was used to implant different doses of NH on pre-sprayed MWCNT substrates (silicon dioxide) 2 + Ions; where NH 2 + The ion flow rate is 6 μA; the background vacuum is 1×10 -7 Torr; field current is 2.27A; NH 2 + The implantation energy of the ion beam is 40KeV; by controlling the implantation dose (1×10 16 ions / cm 2 ) to inject NH on MWCNTs 2 + ion, to get NH 2 + Ion-implanted multi-walled carbon nanotubes on silica wafers. The N element content of the prepared material was 0.56%.

Embodiment 3

[0055] Study on the adhesion and growth behavior of mouse fibroblasts (purchased from the Second Affiliated Hospital of Tianjin Medical University) and human vascular endothelial cells (purchased from Tianjin Armed Police Medical College):

[0056] First, heat the used calf serum, 1640 culture medium (high-sugar DMEM culture medium for endothelial cells), and penicillin-streptomycin solution to 37°C to thaw. 1640 culture solution or high-sugar DMEM culture solution (89%), penicillin-streptomycin solution (1%) ratio to prepare fibroblast culture medium (or endothelial cell culture medium) 50ml, and then put it in the refrigerator for later use; Dissolve phosphate buffer powder in 500ml triple-distilled water to obtain PBS buffer solution for use; enzyme preparation: 1.25g of enzyme is needed for every 500ml of trypsin, mixed with 250ml of PBS, then add 250ml of triple-distilled water, filter through the filter Then put it in the refrigerator to freeze. The cells used in the ex...

Abstract

The invention relates to a multi-wall carbon nanotube injected with NH<2+> ions. NH<2+> ions are injected onto a sprayed carbon nanotube by using an ion injection method, wherein the dosage of the injected NH<2+> ions is 5*1,014-1*1,016 ions / cm<2>; and the energy of a NH<2+> ion beam is 40keV. The hydrophilicity of the multi-wall carbon nanotube injected with NH<2+> ions further disclosed by the invention is increased remarkably. As proved by an adhesion experiment of a mouse lung fibroblast and a human umbilical vein endothelial cell on the material, the cell compatibility of the multi-wall carbon nanotube can be enhanced through NH<2+> ion injection. As proved by a series of blood experiment results, the multi-wall carbon nanotube injected with NH<2+> ions has high blood compatibility, so that the material has high research and application values and wide application prospect in the fields of tissue scaffolds and the like.
