NanoPlus Grids: Hydrophilic, positive charge grid; 50 x 50µm, 25nm thickness; Pack of 10
NanoPlus Grids are hydrophilic and have SiO2 windows with positive surface charge. They provide the broadest applicability of our SMART Grid product line for nanomaterials characterization. Particles with negative partial surface charge "stick" to the grid surface through electrostatic interaction by simply immersing in a drop of solution and then rinsing. This rapid sample preparation method results in uniform distribution of the material across the grid surface with minimal agglomeration for accurate, reproducible metrology. See our gold citrate nanoparticle sample preparation video for more information.
- Window Size: 50 x 50 µm

There are a wide range of materials that have an affinity for NanoPlus grids including metal citrate and other colloidal NPs, carbon black, polymer beads, metal oxides and other ceramics, and functionalized metal and semiconductor nanoparticles.
NanoPlus SMART Grids were the exclusive TEM grids used by the National Institute of Standards and Technology (NIST) in their recent study to establish standards for nanomaterials characterization using Standard Reference gold nanoparticles. NanoPlus Grids are also being used for standardized characterization of silver nanoparticles.
