Claims15
An antimicrobial agent comprising carbon-group non-oxide nanoparticles having an average particle size of 5 to 400 nm.
A method for producing an antimicrobial agent, the method comprising the steps of:
- (a) producing carbon-group non-oxide nanoparticles having a first oxide layer formed thereon;
- (b1) producing a mixed solution by mixing the carbon-group non-oxide nanoparticles with one selected from the group consisting of an alcohol, a carboxylic acid, an aqueous boric acid solution, and water;
- and
- (c1) applying ultrasonic waves to the mixed solution.

- (b2) producing a first mixed solution by mixing the carbon-group non-oxide nanoparticles with a first solution comprising boric acid and an organic solvent;
- (c2) obtaining carbon-group non-oxide nanoparticles having a second oxide layer consisting of a boron oxide formed on the first oxide layer by applying ultrasonic waves to the first mixed solution;
- (d) producing a second mixed solution by mixing the carbon-group non-oxide nanoparticles with one selected from the group consisting of an alcohol, a carboxylic acid, an aqueous boric acid solution, and water;
- and
- (e) applying ultrasonic waves to the second mixed solution.
