Transmission Electron Microscopy of GpdQ bound to G3-MNP

The TEM sample preparation of the immobilized enzyme was difficult since only water could be used to suspend the nanoparticles (usually a more volatile solvent is 

The images demonstrate that the nanoparticles are surrounded by an organic matter which is presumably the enzyme. Analysis of the diffraction patterns of the darker spots confirmed them to be Fe304.
