Application

Used to study mechanism of membrane dysruption by bis(biguanide) molecules.

Actions biochimiques/physiologiques

Chlorhexidine is a cationic broad-spectrum antimicrobial agent belonging to the bis(biguanide) family. Its mechanism of action involves destabilization of the outer bacterial membrane. It is effective against both Gram-positive and Gram-negative bacteria. Chlorhexidine is used primarily as a topical antiseptic/disinfectant in wound healing, at catheterization sites, in various dental applications and in surgical scrubs.

Autres remarques
