TL;DR
Researchers developed a nanogel containing lincomycin-loaded chitosan nanoparticles that effectively promote wound healing and fight bacteria.
Contribution
A novel nanogel system incorporating lincomycin HCl-loaded chitosan nanoparticles for enhanced wound healing and antimicrobial activity.
Findings
The optimized nanoparticles had a mean size of 174.3 nm and 83.7% drug entrapment efficiency.
The nanogel showed sustained drug release (>75% in 24 hours) and strong antibacterial activity against S. aureus and E. coli.
In vivo tests showed almost complete wound closure in 14 days in treated rats compared to controls.
Abstract
The present study focused on developing and evaluating lincomycin HCl (LCH)-loaded chitosan nanoparticles (CSNPs) incorporated into a nanogel system to improve wound healing. CSNPs were prepared via ionic gelation using sodium tripolyphosphate (STPP) as a cross-linker. The optimized formulation showed a mean particle size of 174.3 nm, a polydispersity index (PDI) of 0.267, a zeta potential of +29.4 mV, and a drug entrapment efficiency of 83.7%. FTIR, DSC, and XRD analyses confirmed successful drug encapsulation and stability with no chemical interactions. The formulation demonstrated sustained release (>75% in 24 hours) following non-Fickian kinetics. Antibacterial testing revealed improved efficacy against Staphylococcus aureus and Escherichia coli with inhibition zones of 45 mm ± 2.76 and 38 mm ± 2.15, respectively. In vivo wound healing studies in rats demonstrated almost complete…
