We disclose novel classes of alloy nanocompositions that have superior decontaminant properties which are derived from their superior immediate and residual biocidal properties. By decontaminant properties it is understood that the preferred compositions are antiseptics, disinfectants, sanitizers, and/or sterilizers. By biocidal properties it is understood that the preferred compositions are excellent antimicrobials, antivirals, antifungals, and sporicidals. The preferred compositions have superior immediate and residual biocidal properties in free or bound form and they are safe to humans and environmental friendly. The nanocomposites described herein are in two element, three element or four element combinations. The preferred compositions have additional properties such as they are magnetic and/or they have distinct natural colors. The compositions are produced in different sizes ranging from 5 nm up to 500 nm, and for some other classes above 500 nm.
