Nanoparticle Visualization with an AFM
Although we often know that nanoparticles exist and we have a mental picture of what the nanoparticles look like, it is often helpful to be able to “see” the particles to verify that they are morphologically what we imagine they are.When the particles are less than 1 micron in diameter, they cannot be directly visualized with an optical microscope.......
Particle Size Measurements with an AFM
An atomic force microscope is an excellent for visualizing particles with sizes ranging from 1nm to 10 micron. Another advantage of the AFM is its simplicity of operation and that the AFM requires minimal sample preparation.Additionally, the AFM can operate in air, liquid or a vacuum. In comparison to traditional techniques for single particle analysis of sub micron particles, the AFM gives three dimensional profiles...... |
