In this research, the 1T/2H MoS/FeO/Ag ternary nanocomposite was fabricated, and its features were compared with MoS. Characterization was carried out by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy, UV–visible spectroscopy, vibrating sample magnetometry, and Zeta potential analysis. Adsorption, antibacterial, and anticancer activities were also studied for this nanocomposite. To find the best removal efficiency of methylene blue adsorption under ultrasonic conditions were examined at three levels of pH (5, 7, and 9), methylene blue concentration (5, 10, and 20 ppm), nanocomposite dosage (2, 4, and 6 mg), and ultrasonic time (3, 6, and 12 min) using the L9 (3^4) orthogonal array of Taguchi's method in design of experiment. 97% removal efficiency was found at 5, 20 ppm, 2 mg, and 3 min for pH, methylene blue concentration, nanocomposite dosage, and ultrasonic time, respectively. Additionally, in-vitro studies of antibacterial activity (for and ) and cytotoxicity (for HCT-116 and NIH-3T3 cell lines) of the nanocomposite were studied. The half minimum inhibitory concentration of and were calculated at 13.09 and 49.54 , respectively. The half-maximal inhibitory concentration of the HCT-116 was obtained at 57.16 and 42.52 for 24 and 48 h, respectively.
