 A use of colour to visualise tumour tissues was reported in 2012, using the peroxidase mimesis of MNP coated with a protein which recognises cancer cells and binds to them.Also in 2012, nanowires of vanadium pentoxide (vanadia, V2O5) were shown to suppress marine biofouling by mimicry of vanadium haloperoxidase, with anticipated ecological benefits.A study at a different centre two years later reported V2O5 showing mimicry of glutathione peroxidase, in in-vitro mammalian cells, suggesting future therapeutic application.
