Tannic acid (TA) is a potent antitumor agent, but its low bioavailability and absorption limit use. In this study, it was loaded into chitosan-based nanoparticles (Chi-NPs) to overcome these limitations improve antimicrobial anticancer activities. TA-loaded Chi-NPs (Chi-TA-NPs) were synthesized using the ionic gelation method physicochemically characterized by FE-SEM, FTIR, XRD, PDI, DLS, zeta potential analysis. Additionally, activity of Chi-TA-NPs against two G+ bacterial strains, G- fungal strain (Candida albicans) investigated microbroth dilution method.

Osteomyelitis is a devastating disease caused by microbial infection in deep bone tissue. Its high recurrence rate and impaired restoration of deficiencies are major challenges treatment. Microbes have evolved numerous mechanisms to effectively evade host intrinsic adaptive immune attacks persistently localize the host, such as drug-resistant bacteria, biofilms, persister cells, intracellular small colony variants (SCVs). Moreover, microbial-mediated dysregulation microenvironment impedes regeneration process, leading defect repair. Despite advances surgical strategies drug applications for treatment infections within last decade, remain clinical management. The development application tissue engineering materials provided new infections, but comprehensive review their research progress lacking. This discusses critical pathogenic microbes skeletal system immunomodulatory effects on regeneration, highlights prospects technologies infections.
