  • POLYMER COACERAVATES AND METHODS OF DISRUPTING AND REMOVING BIOFILMS
    Publication number: 20250261642
    Abstract: A polyester coacervate capable of disrupting biofilms formed on substrates and methods of treating contaminated substrates to disrupt and remove biofilms using polyester coacervates without the need for antibiotic therapies or mechanical disruption. The polyester coacervate exhibits tunable viscosity, hydrophobic/hydrophilic, and interfacial properties to disrupt and remove a broad range of biofilms formed on a broad range of substrates.
