A solution containing 3-Mercaptopropyltr-imethoxysilane(MPTMS) was employed to modify surface of cotton fabrics with a silver colloid. Silver nanoparticles were applied on cotton fabrics via treatment with 3-MPTMS. The rate of silver nanoparticles on the fabric surface were measured with Energy Dispersive Spectroscopy(EDS). EDS results confirm the silver atom on the cotton surface.

The surface-enhanced Raman scattering(SERS) of benzylcyanide in a silver sol was investigated. It was concluded that the molecule adsorbed onto the silver surface via the ${\pi}$ system of the CN group. The molecule was assumed to coordinate with either a single atom or two silver atoms. According to the SERS selection rule, the benzene ring of the adsorbed species seemed to assume a flat stance with respect to the silver surface.

1. After the Chu Dynasty(周代), we can confirm the fish shape mark made of stones as the relics of the Chunkuk dynasty(戰國時代). In the Shu Dynasty(隋代), the system of bamboo and the rabbit shape mark made of silver into the fish shape mark. As it were, made of bamboo or siltier changed into the fish shape mark made of jade, gold, silver or wood. 2. In the Dang Dynasty(唐代), the used the fish shape credit mark made of jade, gold, silver, copper or textile, according to their classes. According to one's posit the man who wore purple, red coat, credit mark made a gold and silver. attached with putting them in fish bags. 3. In the Ryo Dynasty(遼代), there was also a system of attaching marks. The emperor was hanging the fish shape and the officials attached the double fish shape to the common dress. fish shape of jade. gold, amber, agate, silver or copper. without any fish bag. 4. The Song Dynasty(宋代) followed the system of the Dang Dynasty they used only the fish shape bags without marks in them. Hanging the fish shape bags made of gold and silver at the back side of the belt. 5. The Gin Dynasty(金代) carried out the system of made jade, gold or silver like the Dang, Song and Ryo Dynasty. In the Sejong Kingdom a system of paper card was carried out as the credit mark of the eighth and the ninth grade. 6. In the Ming Dynasty(明代), the military official general attached the golden, silver, ivory of jade, wood and copper cards with their positions and names. 7. Following the Dang Dynasty, Japan made of fish shape bags to their clothes. Colors of their fish shape marks were same as their clothes. They made the marks, such as crystal, cow's horn, lead and nickel and plated them with gold or silver. 8. In Korea, Pohai(발해) established the fish shape credit mark differed in material. gold, silver or copper according to their positions. We can confirm the Unified Silla(南國;統一新羅), carried out the system of attaching the fish shape in Chonma Chong(천마총), Golden Crown Chong(金冠塚), the King's 13-17 belt ring unearthed at the north part of Court South threat Chong(황남대총), the fish shape golden or silver, to their purple or red ceremonial coats. In the Koryo Dynasty(高麗), like the Dang, Song and Pohai, they attached the fish shape golden or silver marks, to their purple or red ceremonial coats.

Recently, there is much interest in the antimicrobial activity of silver since silver has known to be safe and effective as a disinfectant or an antimicrobial agent against a broad spectrum of microorganisms. Although silver has been applied to various kinds of products due to the effective antimicrobial activity, the quantitative antimicrobial activity or detailed mechanism of silver is not clearly investigated yet, causing the controversy and confusion. In this review paper, we summarized the characteristics, antimicrobial activities and mechanisms, synergistic effects with other antimicrobials, and applicability of silver.

Quantitative analysis of silver from the thermal decomposition of chlorinated polymer contained nano silver is described. The chlorine contained in the chlorinated polymer (e.g. PVC) is liberated as hydrochloric acid gas by heating and a lot of silver produces AgCl. $HNO_3$ and $NH_4OH$ were used for dissolving the Ag and the AgCl. The silver complex was formed by $NH_4OH$. Then the complex was decomposed to silver by heating at $500^{\circ}C$ and the Ag was dissolved by dilute $HNO_3$. Recovery of silver in PVC material was 99.0%.
