■要約
.Silver has been known to be a bactericide for at least 1200 years. Even in ancient times, it was known to prevent diseases and it was said that diseases could not be transmitted by drinking from a silver cup. Silver coins were commonly dropped into a jar to prevent the spoilage of milk and other drink, and silver containers were used to prolong the freshness of food in general. Until almost 1970, it was common usage for scientists to put silver dime in a petridish to sterilize the dish. Recently, we developed the technique how to control the size of silver particles and the dispersion stability in colloidal solution by using surface active agents. In this report, the effect of surfactants on the particle size and stability in silver colloids are described.
