Antibacterial ceramic nanoparticles, appropriate material for medical devices

Iranian researchers studied the antibacterial properties of a type of ceramic nanoparticles which have proved to be an appropriate material for producing medical devices.

After carrying out complementary studies and obtaining desirable results, these nanoparticles enable the production of medical devices with the ability to eliminate bacteria and microbes.

One of the important issues in the production of medical devices nowadays is the application of materials with high mechanical and thermal strength as well as having appropriate antibacterial properties. Therefore, this study tries to study antibacterial properties of barium titanate ceramic nanoparticles.

Experiments carried out in this research showed that barium titanate nanoparticles with determined amount of zirconium show noticeable antibacterial properties. Therefore, it seems that these ceramic nanoparticles can be an appropriate option to be used in the production of medical devices.

The results are considered a significant approach in the laboratorial production and self-sufficiency of the country in the production of nano-ceramics with high mechanical and thermal strength, and their application in medical and pharmaceutical industries and in target drug delivery systems.

Results showed that these nanoparticles have acceptable antibacterial properties against this species. It was also turned out that bacteria that resist against some antibiotics are sensitive to this nanostructure. For instance, low concentrations of the synthesized nanoparticles can have stronger antibacterial effect in comparison with the common drugs such as kanamycin.

Results of the research have been published in Brazilian Journal of Microbiology, vol. 45, issue 4, 2014, pp. 1393-1399.
