The invention relates to a high-efficiency monatomic silver nanowire antibiotic material which is characterized in that the monatomic silver nanowire of the antibiotic material extends from the orifice of a framework-doped manganese dioxide molecular sieve into a hole. The manganese dioxide molecular sieve is characterized by being of a hollandite type crystal structure; and the hole contains the monatomic silver nanowire or / and A ions (A=K<+>, Na<+> or H<+>). The chemical general formula can be expressed as Agm(A)n[MxMn8-x]O16 (M=Mn<2+> / <3+>, Zn<2+> and Ti<4+>; A=K<+>, Na<+> or H<+>; m<=3; n<=2; and x<=2), [MxMn8-x]O16 represents the framework composition of the manganese dioxide molecular sieve, and Agm(A)n represents the hole composition of the manganese dioxide molecular sieve. By mainly using the sterilization mechanism of catalytic activated oxygen, silver of the monatomic silver nanowire antibiotic material is not consumed in the sterilization process. Based on the synergetic effect of the quantized monatomic silver nanowire and the hollandite type manganese dioxide molecular sieve, the antibiotic material has extremely high oxygen activation performance, thereby leading to long-acting, high-efficiency and stable broad-spectrum antibiotic capability and having no adverse side effect on a human body. Thus, the antibiotic material can be widely used for preparing various antibiotic products such as paint, plastic, rubber, textile and the like.

This invention relates to a method for manufacturing surface anti-bacterium product by a physical gas phase deposition technology including utilizing the physical gas phase deposition technology to plate an anti-bacterium target material on a matrix surface to form a film, characterizing in drilling small air holes on said anti-bacterium target and penetrating reaction gas by windpipes, in which, said target is made of As, Se, Hg, Ag, Cu, Zn, CE, Ca, Co, Ni, Al, Fe, S and their oxides, which drills holes on the target surface to prevent the target from poisoning to realize multi-arc plating and magnetic controlled sputtering plating.

This invention relates to a moisturizing skin ointment composition consisting of polymyxin B Sulfate, bacitracin zinc, neomycin (the combination of which totals 1 ounce), hydrocortisone acetate (1 ounce) and white petrolatum (13 ounces). When combined and water evaporated, an external ointment that penetrates the skin and alleviates dry skin conditions, itching and minor scrapes and scratches is created. The properties of the antibiotic products help to promote healing of minor scrapes and scratches as well as preventing the spread of dry skin conditions. The properties of the hydrocortisone aids in the alleviation of itching associated with dry skin. Because this ointment penetrates the dermis almost immediately, the moisturizing properties of petrolatum allows the full benefit of the antibiotic products and hydrocortison to remain on / in the skin through several washings thereby alleviating the need to reapply several times a day.
