Mode for forming nano-silver coating film on stem cell culture suction tube under assistance of magnetron sputtering and chemical gradient sedimentation

Abstract

The invention discloses a mode for forming a nano-silver coating film on a stem cell culture suction tube under the assistance of magnetron sputtering and chemical gradient sedimentation, which comprises the following steps that a, the stem cell culture suction tube is disinfected and is cleaned through high-frequency oscillation; b, the stem cell culture suction tube is placed in a steady state, a three-dimensional maximum diameter under a horizontal condition is removed, a silver target is customized, and the stem cell culture suction tube is placed into the silver target; c, bombarding is conducted on the target object silver target through electromagnetic sputtering, a copper wire of 860 turns with the diameter of 0.1 cm is wound on an outer target on the outer side of a magnetron sputtering vacuum chamber, the vacuum chamber is cleaned, the substrate material (the stem cell culture suction tube) is placed in an inner target, the vacuum chamber is sealed and starts to be vacuumized with the vacuum degree being 10 <-6 >; and d, inert gas is input into the vacuum chamber for filling. The stem cell culture suction tube formed by the invention has the effects of killing bacteria, fungi, mycoplasma, chlamydia, spirochete and even trichomonad in clinical use, and does not generate drug resistance.

Description

technical field [0001] The invention relates to the technical fields of biomedicine, biomedicine, nanotechnology and chemical gradient sedimentation, in particular to a method for forming a nano-silver coating on stem cell culture straws assisted by magnetron sputtering and chemical gradient sedimentation. Background technique [0002] Nanometer (nm) is the smallest unit of measurement after the micron in the physics world, with the development of nanotechnology. A large number of nanomaterials have been found to have antiphysical phenomena. As well as the quality and effect of special functions, nano-silver is also after the extensive development of metal nano-materials. an emerging field of research. Silver in the nanometer state has produced a qualitative leap in the bactericidal ability used in biomedicine. A very small amount of nano-silver can produce a powerful bactericidal effect that was unimaginable in the past. Nano-silver can kill more than 650 kinds of bacter...

Problems solved by technology

[0003] Stem cell culture straws in the prior art are ordinary polymer materials, which cannot effectively protect stem cells from being corroded by external microorganisms, especially the erosive growth of bacteria during the process of culturing stem cells.

[0004] Moreover, ordinary polymer stem cell culture straws cannot improve the microcirculation of the tissue around the wound, and at the same time cannot effectively promote wound healing, rapidly promote the repair and regeneration of damaged cells, and fail to eliminate the inflammatory response

Can not effectively activate and promote the growth of damaged tissue cells, reduce scar formation, and accelerate wound healing
