Attorney, Agent or FirmInternational ClassesA10N 059/16A61K 009/24 A61N 025/00 AbstractThe present invention relates to nanosilver-containing antibacterial and antifungal granules ("NAGs"). The NAGs have longlasting inhibitory effect on a broad-spectrum of bacteria and fungi, which include, but are not limited to, Escherichia coli, Methicillin resistant Staphylococcus aureus, Chlamydia trachomatis, Providencia stuartii, Vibrio vulnificus, Pneumobacillus, Nitrate-negative bacillus, Staphylococcus aureus, Candida albicans, Bacillus cloacae, Bacillus allantoides, Morgan's bacillus (Salmonella morgani), Pseudomonas maltophila, Pseudomonas aeruginosa, Neisseria gonorrhoeae, Bacillus subtilis, Bacillus foecalis alkaligenes, Streptococcus hemolyticus B, Citrobacter, and Salmonella paratyphi C. The NAGs contain ground stalk marrow of the plant Juncus effusus L. which has been dispersed with nanosilver particles. The nanosilver particles are about 1-100 nm in diameter. Each of the nanosilver particles contain a metallic silver core which is surrounded by silver oxide. The present invention also provides a process for making the NAGs. The NAGs can be used in a variety of healthcare and industrial products. Examples of the healthcare products include, but are not limited to, ointments or lotions to treat skin trauma, soaking solutions or cleansing solutions for dental or women hygiene, medications for treating gastrointestinal bacteria infections, sexual related diseases, and eye diseases. Examples of industrial products include, but are not limited to, food preservatives, water disinfectants, paper disinfectants, construction filling materials (to prevent mold formation). | |
