From: Photocatalytic, antimicrobial and antibiofilm activities of MgFe2O4 magnetic nanoparticles
Antibiofilm activity of MgFe2O4 NPs E. coli using the tube adherence method. (A) Growth of bacterial cells and biofilm formation (rings) without treatment with MgFe2O4 NPs (left) and the inhibition of bacterial growth after treatment with MgFe2O4 NPs (right). (B) Staining of the adherent bacterial cells with crystal violet. (C) Removing and dissolving the adherent bacterial cells by ethanol for determination of quantitative biofilm inhibition (%). (D) Quantitative analysis of antibiofilm activity of MgFe2O4 NPs. The optical density (OD) of both the control sample (without MgFe2O4) and of the treated samples with 10ug/ml MgFe2O4 was measured at a wave length of 570 nm.
