Tittle:
Magnetically-driven Fe3O4@Ag nanocomposites with a magnetic core and size tunable silver nanoparticles
Summary:
A Czech research centre has developed a technology for a synthesis of magnetic Fe3O4@Ag nanocomposites with a magnetic core. This material possesses a remarkably high antimicrobial effect against a wide range of bacterial strains and yeasts. Material can be also successfully applied as a substrate in surface enhanced Raman spectroscopy. The university center searches for a public or private partner for a license or commercial agreement with technical assistance.
Description:
Presented Fe3O4@Ag nanocomposite developed by the Czech university presents an unique solution for a treatment of bacterial contamination using novel biocompatible magnetic core and size tunable silver nanoparticles.
The nanocomposite is multimodal in action. This includes simply to obtain extraction of the material using magnetic force with remarkably high efficiency, tunable properties of present silver nanoparticles with a consecutive influence on the possessed antimicrobial effect.

Ecotoxicological experiments showed that Fe3O4@Ag nanocomposite has a high antimicrobial activity. Values of minimum inhibitory concentration (MIC) for yeast fall into a range 0.9 - 12.6 mg/L, and MIC values for bacteria are lower than 50 mg/L for all tested strains.

The material possesses a remarkably high antimicrobial effect against a wide range of bacterial strains and yeasts, including Enterococcus, Pseudomonas, Escherichia and Candida species.
Antimicrobial effect is utilizable in various cases, including water treatment small and medium-sized enterprises (SMEs), cleaning up of medicinal facilities, etc.

Activity in surface enhanced Raman scattering (SERS) is utilizable in a development of analytical procedures for a detection of various chemical targets.

The university center searches for a public or private partner for a license or commercial agreement with technical assistance.
Advantages and Innovations:
The offered material is unique in terms of biogenic properties of its magnetic core and high antimicrobial activity of immobilized silver nanoparticles, demonstrated on a wide range of bacteria and yeast strains.

Main advantages of this products are as follows:
1. Presented nanocomposite is magnetically driven. This means that the material can be extracted from the sample using simple magnetic force with ultra-high efficiency.
2. Incorporated magnetic core is biocompatible, and is thus applicable in bio-medicinal cases.
3. Present silver nanoparticles can be tuned to achieve desired shape and size.
4. Present silver nanoparticles have high antimicrobial activity.
5. Material has a high activity in surface enhanced Raman spectroscopy. Material can be thus utilized as a suitable substrate in many procedures for analysis of chemical targets including nucleic acids and proteins.
