Harnessing the extracellular bacterial production of nanoscale cobalt ferrite with exploitable magnetic properties.

We demonstrated a method for dramatically altering magnetic properties of biologically produced nanoparticles that has potential for scale up using bioreactors. The results of this work inspired our subsequent publications on tailored biogenic nanoparticles for biomedical applications such as cancer therapy and magnetic resonance imaging (J Byrne et al, Royal Soc. Int. 83, 20130134 (2013); J Byrne et al, Adv. Fun. Mater. 2013 (under review), J Byrne et al, Nanotechnology 22, 455709 (2011)). Further international impact includes invited talks (e.g. 2013 EMN Fall Meeting, Orlanda USA) and EU Marie Curie funding (MAGNETICFUN (290248)). Telling/Coker are joint lead-authors on this paper.
