Summary
New antimicrobial polyelectrolytes (PEs) functionalized with essential oils were developed for drug delivery systems. These functionalized particles show effective drug encapsulation and controlled release, offering potential for treating infections.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Developing multipurpose particles with tailored coatings is key to modifying physicochemical and biological properties.
- Antimicrobial functionalization of carrier systems is crucial for combating infections.
Purpose of the Study:
- To design and prepare novel polyelectrolytes (PEs) with antimicrobial functionality (PEs-DAF) for use in carrier systems.
- To create hydrogel nano- and microparticles coated with these antimicrobial PEs.
- To evaluate the potential of these systems as drug carriers.
Main Methods:
- Poly-(acrylic acid) (PAA) was grafted with thymol, menthol, and carvacrol using Steglich esterification.
- Particle characterization involved DLS, SEM, TEM, AFM, QCM-D, and ellipsometry.
- Antimicrobial activity was assessed against Staphylococcus aureus and Escherichia coli.
Main Results:
- Novel PEs-DAF were successfully synthesized and characterized.
- Antimicrobial activity was confirmed, with some particles showing enhanced bioactivity.
- Effective encapsulation and controlled release of resveratrol (RES) were demonstrated.
Conclusions:
- The developed antimicrobial-decorated carrier systems show promise for therapeutic applications.
- These systems are suitable for delivering chemotherapeutic agents like RES.
- Potential exists for treating multidrug-resistant pathogenic infections.
