Smart Grids™ represent the next step in TEM grids for sample preparation. These grids are a new revolutionary tool for enhanced visualization at the nanoscale. By creating a functionalized surface, the grid surface itself now becomes part of the sample preparation process. This allows Smart Grids™ the ability to understand function and form at the nanoscale level with applications ranging from materials to life sciences to semiconductor processing.
Smart Grids™ are micromachined from ultrathin silicon wafers to provide the greatest flexibility in grid geometry and configuration. The 3 mm octagon grids have a square window size of 50X50 or 100X100 micron windows with 51 and 34 windows per grid respectively. These grids are machined with a single rectangular window that serves as an index mark for reproducible imaging. Smart Grids™ employ thermally grown SiO2 membrane windows that are available with a standard membrane thickness is 25 nm and the grid thickness is 100 microns. The 25 nm windows are the most generally applicable showing excellent image resolution with minimal background. Most SMART Grids are hydrophilic unless otherwise stated. The membrane windows are robust to a variety of chemical and thermal processing treatments provided they are properly handled. Other thickness and styles are anticipated to be added in the near future.
The Smart Grids™ product line can provide a unique opportunity to image the world of molecular-scale engineering. Smart Grids are more than a replacement grid for transmission electron microscopy (TEM); they can change the way electron microscopy is used and can have wide application for multiple techniques for analytical characterization.
|NanoGrids™ set a new standard for characterization of nanomaterials using TEM, SEM, and AFM. NanoGrids are available with a range of active surfaces to enable uniform dispersion and accurate characterization of many different types of materials by liquid or vapor phase deposition.||BioGrids™ are functionalized SMART Grids that promote affinity for proteins, viruses, or other biomolecules through both non-specific bonding and analyte-specific bonding. BioGrids are suitable for use with both stained samples and cryoEM.|
