摘      要:Manganese-substituted magnetite ferrofluids(FFs)Mnx Fe_(1-x)Fe_(2)O_(4)(x=0–0.8)were prepared in this work through a chemical coprecipitation *** controlled growth of FF nanomaterials for antibacterial activities is challenging,and therefore,very few reports are available on the *** research focuses on stabilizing aqueous FFs with the tetramethylammonium hydroxide surfactant to achieve high *** characterization reveals nanoparticles of 5–11 nm formed by the chemical reaction and nanocrystalline nature,as evident from structural ***-substituted magnetic FFs are analyzed for their structural,functional,and antibacterial performance according to the Mn-substituent *** studies show a high blue shift for Mn^(2+)-substituted Mnx Fe_(1-x)Fe_(2)O_(4)with the theoretical correlation of optical band gaps with the Mn *** superparamagnetic nature of substituted FFs causes zero coercivity and remanence,which consequently influence the particle size,cation distribution,and spin *** structural and functional performance of the FFs is correlated with the antibacterial activity,finally demonstrating the highest inhibition zone formation for Mnx Fe_(1-x)Fe_(2)O_(4)FFs.
