Alginate–zein composite modified with metal organic framework for sulfasalazine delivery

Metal–organic frameworks (MOFs) have promising prospects as drug nanocarriers but are more limited in biomedical applications due to their poor stability and biocompatibility. To address this issue, sodium alginate–zein (SA-ZN) nanocomposites modified metal–organic framework were developed and used as an effective nanocarrier for sulfasalazine (SSZ) delivery and reduced side effects of, thus improving its bioavailability SSZ. The obtained nanocomposite was structurally and morphologically characterized using different physicochemical techniques including Fourier transform infrared (FTIR), X-ray diffraction (XRD), and field-emission scanning electron microscopy (FESEM). Based on the results, the Zn 2 (BDC) 2 (DABCO) MOFs were dispersed in biopolymers. In addition, the antibacterial properties of samples have been studied against Staphylococcus aureus and Pseudomonas aeruginosa . The results showed that the drug-loaded MOF/SA-ZN has a higher antibacterial activity against S. aureus gram-positive bacteria compared to SSZ. The current research provides a promising insight into the fabrication of polymer-modified MOF-based drug delivery platforms and antibacterial agents.
