When combined with the concept of MOFs, which are crystalline structures composed of metal ions or clusters linked by organic ligands, the resulting β-CD-MOF holds immense potential for various applications, especially in the field of drug delivery. In this study, biocompatible metal-organic frameworks (MOFs) synthesized using β-Cyclodextrin (β-CD) and potassium enabled drug delivery of curcumin (CCM) to cancerous cells. Functionalizing β-CDMOF with L-glutamine (glutamine-β-CD-MOF) enhanced cancer cell-specific targeting due to glutamine’s essential role in cancer cell proliferation and energy pathways. Amino group functionalization provided further functionalization opportunities. Gelatin coating (gelatin@β-CDMOF) facilitated controlled drug release in an acidic medium. High drug loading capacities (52.38–55.63 %) were achieved for β-CD-MOF@CCM and glutamine-β-CD-MOF@CCM, leveraging the high porosity and affinity of amine and phenol groups ofcurcumin. The MTT assay highlighted the specificity and differentiation of glutamine-β-CD-MOF in targeting cancerous over normal cells. These functionalized β-CD MOFs efficiently encapsulate curcumin, ensuring controlled drug release and enhanced therapeutic efficacy, particularly in cancer therapy. |\n\n1. Introduction  \nCancer is one of the leading causes of global mortality. Conventional treatments, including radiotherapy, surgery, immunotherapy, and chemotherapy, are yet to achieve complete therapeutic success [1]. Nanotechnology is extensively utilized for therapeutic and diagnostic development. Their properties have made them lucrative candidates for drug delivery systems [2]. Metal-organic frameworks (MOFs) are a class of microporous crystalline coordination polymers consisting of metal nodes or clusters interconnected with these materials [3–6]. The exceptional porosity and high surface area of these structures, together with tuning and designing of a variety of MOFs due to infinite combination of metal nodes and organic ligands, tailorable pore size, biocompatibility and biodegradability, and ease of functionalization of organic ligands, led to the vast potential and application of ions utilized in the synthesis include p-block elements, transition metals, alkaline earth metals, alkaline metals, lanthanides, and actinides [7].
