Pathogen adsorption via immobilized heparin

Molecular classification
Other
01

Overview

Immobilized heparin refers to heparin that is chemically attached to a surface or media, functioning to adsorb and remove pathogens—mainly bacteria—by inhibiting their adhesion to biological or synthetic surfaces[1][2][3]. This anti-adhesive barrier mechanism is used experimentally to prevent infections in mucosal tissues (such as the bladder) or to purify blood by selectively trapping bacteria on heparin-functionalized materials[1][2][3]. Heparin’s action in this context is independent of its anticoagulant properties and is attributed to its mucopolysaccharide structure, which interferes with microbial adhesion[1][2].
