1. A method for inhibiting propagation of microbial species comprising:
- contacting the microbial species with an antimicrobial agent comprising an antimicrobial polyaminosilane,wherein the antimicrobial polyaminosilane is prepared by a process of subjecting only an aminosilane monomer to a hydrolysis and a condensation reaction so that the antimicrobial polyaminosilane has a repeating unit containing only aminosilane and is free of chloride ions,the antimicrobial polyaminosilane contains protonated amino groups carrying positive charges,the antimicrobial polyaminosilane is in a form of polymeric particulates, andthe polymeric particulates are combined to form aggregates having a size less than 100 nm.
