In vitro antiproliferative study of curcumin loaded nano zeolitic imidazolate framework hybrid biomaterials on HeLa cells

•The morphology of ZIF systems (ZIF-8 and ZIF-67) are not altered during the formation of CCM–ZIF hybrid biomaterial.•The average particle size of the ZIFs are reduced to a greater extend by forming CCM–ZIF hybrid biomaterials.•The CCM–ZIF hybrids exhibit an increase in thermal stability than that of ZIFs alone•CCM–ZIF-67 hybrid shows much reduction in cell viability against HeLa cells.
