Many short peptides selectively permeabilize the bacteria plasma membrane, leading to their lyses and death: they are therefore a source of antibacterial molecules and inspiration for novel and more selective drugs, which may have wider application in many other fields, as selective anticancer drugs. In this chapter, it is presented a new method to investigate the permeabilization properties of antimicrobial peptides under strict physiological conditions, employing the patch-clamp technique coupled to a fast perfusion system.
