Background and aim:
The urgent need for breakthrough therapeutic approaches for multi-drug resistance Staphylococcus aureus (MDR) has drawn attention to potential cutting-edge tools like nanoparticles (NPs). The preparation of chitosan/alginate-encapsulated Echinacea angustifolia extract and evaluation of its effectiveness against MDR strains were the goals of this investigation.
Method
Scanning electron microscopy, dynamic light scattering (DLS), and Fourier Transform Infrared spectroscopy were used to analyze the synthesized NPs. Investigations were done into the antibacterial and antibiofilm properties of E. angustifolia NPs. Also, the expression of essential genes in biofilm formation was evaluated by real-time PCR.
Results
According to DLS measurements, spherical E. angustifolia NPs had a diameter of 335.3 ± 1.43 nm. The PDI was 0.681, and the entrapment effectiveness (EE%) of the E. angustifolia extract reached 83.45%. Synthesized NPs had the highest antibacterial power. They also significantly decreased the expression of genes involved in biofilm formation.
Conclusion
By releasing natural-derived medications under regulated conditions, the findings described here should help create new plant extracts with increased stability and antibacterial action, which will help minimize the usage of antibiotics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
