Figure 1From: Rapid and selective separation for mixed proteins with thiol functionalized magnetic nanoparticlesCharacterization, size distribution, XRD patterns, and magnetic attraction image of Si-MNPs. (A) Characterization of Si-MNPs. TEM image shows the core-shell structured, (B) size distribution of Si-MNPs with 40 nm of average particle size (C) XRD patterns of MNPs and Si-MNPs, and (D) pictures showing the magnetic attraction for Si-MNPs.Back to article page
