It can be seen from the AFM photos that the three types of immunomagnetic spheres have similar spherical-like shapes, with not too high uniformity of size distribution, particle size greater than 100 nm, and rough surface of the IML.
As can be found from the AFM photos, the three immunomagnetic balls have similar spherical shapes with less-high size distribution across, particle sizes greater than 100 nm, and rough IML surfaces.
AFM images showed that the three kinds of immunomagnetic spheres had similar spherical shape with less uniform size distribution. The particle size was more than 100 nm and the surface of IML was rough.<br>
