Antimicrobial efficacy and lack of resistance to silane quaternary com

Does the ‘entourage effect’ explain the increase in antimicrobial efficacy and lack of resistance seen with fifth-generation silane quaternary compounds? Here, Andrew Kemp provides an overview of the development and use of such agents.

Decontamination and disinfection are enormous subjects individually and can be of mind-boggling complexity.  The activity of disinfectants against microorganisms depends on a number of factors, some of which are intrinsic qualities of the organism, while others involve the chemical and external physical environment.
