Abstract
Improvement of curative herbal extracts effectiveness through novel drug delivery systems is a field of study for the researches nowadays. Zirconium-based metal-organic frameworks (Zr-MOFs) are one of the most capable porous nanocarriers that need a biocompatible template to be used in biomedical applications. In this work, Zr-MOF was synthesized into the wool fabric through in-situ one-pot method with different molar ratios. The final fabrics were characterized thoroughly using various techniques and the effect of components on monodispersity and nucleation tendency of Zr-MOF onto the surface of wool were explained. The resultant fabric stablished absolute wash durability, increased air-permeability up to twice and reasonable hydrophilicity. Tensile strength and young modulus decreased 30 and 1244 % and strain increased 66 %. Salvia Officinalis (SO) and Calendula Officinalis (CO) extracts were loaded onto the modified fabrics with 1154 and 1842 % increased absorption capacity. The release profiles showed domination of diffusion mechanism. The wool-MOF-SO and CO displayed both 100 % antibacterial activity against Escherichia coli and 60.95 and 64.64 % against Staphylococcus aureus because of diverse antibacterial components. Calendula Officinalis proved biocompatibility with human skin however Salvia Officinalis exhibited high toxicity.
