- quaternary ammonium polyethylenimine nanoparticles
A crosslinked nanoparticle formulation containing quaternary ammonium polyethylenimine (QA-PEI) with potential antibacterial activity. The cationic polymer PEI kills bacteria by rupturing their cell membranes without the development of resistance.
Quaternary ammonium polyethylenimine nanoparticles can be incorporated into dental composite resins or silicon obturator prostheses and may prevent or delay bacterial growth. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
