Abstract

Introduction/Objective

Tuberculosis (TB) remains a persistent global health challenge, with an increasing incidence of cases and limitations in current treatment strategies. Traditional therapy involves long drug treatments that can cause side effects and lead to drug-resistant strains, making treatment less effective. This study aimed to explore the therapeutic potential of a novel nanoparticle-based delivery system for Thymol (THY), a natural antibacterial bioactive molecule, to combat , a model organism for .

Methods

A nanoparticle-based delivery system was developed using biocompatible Thymol-conjugated Chitosan Zinc Ferrite Nanoparticles (THY-CH-ZnFeO NPs). The nanoconjugates were characterized for their morphological and chemical properties.

Results

The characterization of synthesised nanoparticles showed THY-CH-ZnFeO NPs to exhibit enhanced biocompatibility and antibacterial activity against compared to THY alone. The nanoconjugates induced Reactive Oxygen Species (ROS)-mediated damage to the bacterial cell membrane, effectively inhibiting bacterial replication, dormancy, and biofilm formation. Additionally, the nanoconjugates demonstrated low cytotoxicity towards the human kidney cell line.

Conclusion

The study's findings highlighted a new direction for developing nanoparticle-based antimycobacterial agents with a wide application in treating TB and other bacterial diseases. The THY-CH-ZnFe2O4 NPs show promise as a safe and effective therapeutic agent, offering a potential solution to the limitations of current TB treatment strategies.
