NANOMETRE SIZE CONTROL (N): We provide the user with the option of controlling particle size down to 1 nanometre (10 Angstroms, 0.001 microns). This allows the user to choose or emphasize quality over quantity or the opposite. Quality (small particles) is important to inactivate small vicious viruses and to pass through the blood-brain barrier. All of our models now have nanometer-size control. For the utmost in quality, turn this knob down to the lowest level for the smallest Nanoparticles of 1-2 nm.
