Russia develops new technology to enhance the antibacterial effect of titanium alloys to speed up wound recovery

 The Russian National Research University of Technology and the other Russian scholars have developed a new technology which can make titanium alloy, one of the key materials for advancing surgery, produced antibacterial effects.which is reported by Technology Daily . Researchers said that implants processed via the new method will significantly  quickly and promote wound recovery. Also relevant research results are publishing in the journal of "Colloid and Surface B: Biological Interface".

The mechanical performance and recovery ability  for damaged bones ,which will decrease significantly with age, and this damage will require long-term treatment. To use of implants made by unmodified metals and alloys might cause complications, which maybe requires a second surgical operation afterwards. Materials that can inhibit the activity of bacteria can help make implant operations in the body safer and more reliable. So, Russian scholars have developed a method to spraying antibacterial coatings on Ti-Zr-Nb, which is one of the titanium alloys.

Tests  shown that treatment with the new method can completely inhibit the growth of E. coli on the implant  surface . At a low dose of silver output (approximately 0.037 mg/L), it is completely safe for the body and achieves a significant antibacterial effect. Researchers said that the "strike" against bacteria is carried out via silver ions. Scientists chemically synthesized nanoparticles that released it in a complex alcohol solution, which made it only about 10 nanometers in size. To benifit on  this, silver is deposited in the pores of the material ,and the depth nearly 60 nanometers, which  improves the durability effect and antibacte  rial effect for the coating
