Problems solved by technology

[0005] The silver ion method believes that silver ions undergo a substitution reaction with the thiol group (-SH) present in the protein of the bacteria, thereby inactivating the protein of the bacteria, resulting in the inactivation of the bacteria

Embodiment

[0126]

[0127] 101.922 mg of silver nitrate was dissolved in 60 mL of ultrapure water to prepare a solution containing silver ions at a concentration of 10 mM.

[0128] 656.172 mg of tetraethylammonium=bromide was dissolved in 20 mL of toluene to prepare a solution containing tetraethylammonium=bromide at a concentration of 60 mM.

[0129] The above two solutions were mixed in an eggplant-shaped flask, further, 120 mL of toluene was added to the eggplant-shaped flask, and then the mixed solution of the three substances was stirred for 24 hours.

[0130] 10-Carboxy-1-dodecanethiol (CDT) was dissolved in 20 mL of toluene to prepare three solutions containing protective agents with CDT concentrations of 1 mM, 5 mM and 10 mM, respectively.

[0131] After each solution containing a protective agent was added to the above-mentioned mixed solution, it was stirred for 48 hours or more. Thereby, 10-carboxy-1-dodecanethiol was adsorbed on the silver ion.

[0132] 226.98 mg of sodiu...

Abstract

The invention relates to a method for controlling particle size of silver particles, silver particles, an antimicrobial agent containing silver particles, and use thereof. A mixed solution is manufactured by adding a thiol represented as the formula HS-R-A (wherein, R is an arbitrary organic group, and A is an arbitrary active functional group) to a solution containing silver ions, and silver particles are manufactured by aggregating the silver ions using a method comprising the steps of adjusting the amount of the thiol added to the solution and adding a reducing agent to the mixed solution.

Description

technical field [0001] The present invention relates to a method for producing silver particle diameter, silver particle, antibacterial agent containing silver particle and utilization thereof. Background technique [0002] Silver is known to have antimicrobial activity. Currently, the mechanism by which silver exhibits antibacterial activity is being continuously investigated. [0003] Although there are various theories about the mechanism by which silver exhibits antibacterial activity, the mechanism is still not fully understood. [0004] For example, Non-Patent Document 1 proposes a mechanism for explaining that silver has antibacterial activity, and cites a silver ion method and an active oxygen method. [0005] In the silver ion method, it is considered that silver ions undergo a substitution reaction with a thiol group (-SH) present in a bacterial protein, thereby inactivating the bacterial protein, resulting in the bacterial inactivation. [0006] On the other ha...
