Background
In recent years, nanomaterials have attracted much more attention because of their potential broad-spectrum antimicrobial activity. However, finding biofunctional nanomaterials is still challenging. Therefore,we prepared a new type of recyclable [email protected] nanomaterials with a very simple method named displacement reaction.
Methods
[email protected] nanomaterials were prepared in AgNO3 solution with cobalt nanomaterials as the core, while the surface was coated with silver nanomaterials. [email protected] nanomaterials were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and oscillating sample magnetometer (VSM).In order to evaluate the bacteriostatic effect of [email protected] nanomaterials, we used qualitative and quantitative methods to assess the bacteriostatic effect of these materials on standard strains of Pseudomonas aeruginosa (ATCC27853, Gram - negative bacterium), Staphylococcus aureus (ATCC 25923, Gram-positive bacterium), Escherichia coli (ATCC 25922, Gram-negative bacterium) and Candida albicans (ATTC 90029, yeast) in Yellow River water in vitro.
Results
We found that the diameter of the [email protected] nanomaterials was about 100nm, which was exhibited in form of elemental elements and obvious magnetic properties.The results show that [email protected] nanomaterials have excellent antibacterial effects on Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Candida albicans and the bacteria in the water of the Yellow River.
Conclusions
[email protected] nanomaterials have a significant antibacterial effect and can be recycled through an external magnetic field to reduce environmental pollution. Interestingly, the reclaimed [email protected] nanomaterials can still have antibacterial activity and can be reused. These results indicate that [email protected] nanomaterials may have potential application as disinfectants for water.
