Abstract
Techniques regarding star polymers with enhanced antimicrobial functionality are provided. For example, a polymer is provided that can comprise a core that can have a singlet oxygen generator and that can generate a singlet oxygen species upon irradiation with light. The polymer can also comprise a plurality of polycarbonate arms covalently bonded to the core. The plurality of polycarbonate arms can be degradable and can comprise a cation. Further, the plurality of polycarbonate arms can have antimicrobial functionality.
Claims12
A method, comprising:
- forming a plurality of degradable polycarbonate arms by polymerizing a plurality of carbonates with a singlet oxygen generator core, wherein the singlet oxygen generator core generates a singlet oxygen species in response to being irradiated with light having a wavelength within 10 nanometers to 750 nanometers;
- and
- generating a cationic moiety by covalently bonding a functional group with a degradable polycarbonate arm from the plurality of degradable polycarbonate arms.
