Introduction to Metal-Organic Frameworks
Metal-organic frameworks (MOFs) are crystalline porous materials formed by the coordination of metal ions or clusters with organic ligands. Their tunable porosity, high surface area, and versatile functionalization make MOFs a rapidly expanding platform in biological research and biomedical applications. Among the various MOFs, those based on zinc and phosphonic acids have attracted significant scientific interest due to their exceptional biocompatibility, stability, and multifunctionality.
Applications in Biological Research
-
Antimicrobial and Infection Control: Zn-MOFs and Ag-MOFs incorporating phosphonic acid ligands exhibit broad-spectrum antibacterial activity by disrupting bacterial membranes and interfering with DNA replication, useful for wound healing and infection mitigation.
-
Drug Delivery and Theranostics: MOFs serve as carriers for controlled release of antibiotics, chemotherapeutics, and imaging agents, enabling precision medicine approaches.
-
Photothermal and Chemodynamic Therapy: Zn/Ag-doped MOF derivatives demonstrate synergistic effects achievable through efficient ion release and photothermal conversion, targeting pathogens such as Staphylococcus aureus and Escherichia coli effectively.
-
Biosensing and Diagnostics: Porous architectures facilitate immobilization of biomolecules, enhancing sensitivity and selectivity for molecular detection.
