NanoMinus grids are hydrophilic and have electron transparent SiO2 windows with negative surface charge. Particles with positive partial surface charge "stick" to the grid surface through electrostatic interaction. Simply immersing the NanoMinus grid in a drop of solution and then rinsing results in uniform distribution of the material across the grid surface with minimal agglomeration for accurate, reproducible metrology. NanoMinus Grids also improve the reproducibility of samples prepared using drop-casting, dip-coating, or aerosol deposition methods.
NanoMinus Grids aid in sample preparation for a variety of nanomaterials including quaternary and primary amine derivatized particles, lysine coated particles, Lewis acids, and other cationic materials.
