Figure 1. SPION functionalization and properties.

Figure 1

(a) Forces generated by the electromagnet at different voltages and different distances from its tip with 10 nm and 40 nm diameter iron core SPIONs. (b) Diagram for 40 nm SPION chemical coupling to cholera toxin B or anti- (α-) Thy1 antibody. (c) Functionalized SPIONs migrate slower in agarose electrophoresis, demonstrating successful chemical coupling.
