Synergistic effect of SrTiO3/CuFe2O4/MIL-101(Co) as a MOF composite under Gamma-rays for antimicrobial potential versus bacteria and pathogenic fungi.

ABSTRACT

The primary emphasis of this study was on the innovative and scientifically valuable hydrothermal synthesis of MIL-101(Co) as a metal-organic framework (MOF) material. Subsequently, the CuFe2O4 was incorporated into the MOF by a reduction-precipitation technique. The SrTiO3/CuFe2O4/MIL-101(Co) composite was synthesized by using hydrothermal in situ growth process. The XRD and FESEM investigations of the SrTiO3/CuFe2O4/MIL-101(Co) composite definitively verified its crystalline structure and proved its production with exact shape and dimensions. The data indicated that Candida albicans displayed the greatest vulnerability to all three produced materials, with reported Minimum Inhibitory Concentration (MIC) values of 500 µg mL-1 for MIL-101(Co). The CuFe2O4/MIL-101(Co) compound, when produced, exhibits MIC values of 200 µg mL-1. Additionally, the combination of CuFe2O4/MIL-101(Co) with SrTiO3, shows MIC values of 50 µg mL-1. The results also indicated that the MIC values for MIL-101(Co), and CuFe2O4/MIL-101(Co) against S. aureus were 100 µg mL-1. Ultimately, SrTiO3/CuFe2O4/MIL-101(Co) exhibited identical MIC values of 50 µg mL-1 against S. aureus. The concentration of the bacterial protein was increased by adding MIL-101(Co), CuFe2O4/MIL-101(Co), and SrTiO3/CuFe2O4/MIL-101(Co). The antibacterial capabilities of the SrTiO3/CuFe2O4/MIL-101(Co) were increased after being subjected to gamma doses of 100.0 kGy. This process paves a ways for manufacturing innovation in near future.
