Popis:	The cold atmospheric plasma in liquid (CAPL) technique was carried out in DI water as the solution to create Fe3O4-doped ZnO nanoparticles by adjusting the concentration (0.01, 0.02 and 0.03) M at ([Formula: see text][Formula: see text]kV, [Formula: see text][Formula: see text]mA and flow rate = 3[Formula: see text]L/min), while the exposure period was 3[Formula: see text]min. A UV-Vis. spectrophotometer, X-ray diffraction and field emission spectroscopy (FE-SEM) were used. The energy of the bandgap was discovered to be (2.95–2.85) eV. The form and dimensions obtained by FE-SEM have not changed much. All materials were tested against inactivated positive and negative gram bacteria (S. aureaus and E. coli) and showed promising antibacterial capabilities, especially Fe3O4-doped ZnO, which can inactivate bacteria under typical laboratory light.
