Drp-Au-AgNPs demonstrated greater degradation ability (83.68%) of MG than D. radiodurans cells and monometallic AuNPs. The major degradation product was identified as 4-(dimethylamino) benzophenone, which is less toxic than MG. The degradation of MG was mainly attributed to the capping proteins on Drp-Au-AgNPs. The bimetallic NPs could be reused and maintained MG degradation ability (> 64%) after 2 cycles.Conclusion: These results suggest that the easily prepared Drp-Au-AgNPs have potential applications as novel nanomedicine for MG detoxification, and nanomaterial for biotreatment of a toxic polyphenyl dye-containing wastewater.Keywords: bimetallic nanoparticles, Deinococcus radiodurans, biodegradation, toxic triphenylmethane dye, malachite green, detoxificationWeng YLi JDing XWang BDai SZhou YPang RZhao YXu HTian BHua YDove Medical Pressarticlebimetallic nanoparticlesdeinococcus radioduransbiodegradationtoxic triphenylmethane dyemalachite greendetoxificationMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 1823-1835 (2020)
