SUBSTRATES FOR HIGH-RESOLUTION IMAGING

If you are looking for TEM window grids for high-resolution imaging of nanoparticles or nanotubes, we would recommend the following TEM Windows:

  • Non-porous 5 nm thick UltraSM® TEM Windows are the thinnest imaging, plasma cleanable substrate we offer and have less chromatic blur than even ultrathin carbon.
  • Non-porous 9 nm thick UltraSM® TEM Windows are more robust than the 5 nm films and are suitable for sample preparation procedures that might include several wet-dry steps. For truly rugged substrates see our films for deposition below
  • Porous 15 nm thick UltraSM® TEMwindows have 10-50 nm diameter nanopores to suspended material across for truly background-free imaging

 

SUBSTRATES FOR SAMPLE DEPOSITION & ANALYSIS


If you need a robust substrate on which to deposit films or grow nanoparticles or nanowires, we recommend the following TEM Windows:

  • Non-porous 15 nm thick UltraSM TEM Windows are our most robust pure silicon films. These amorphous films offer plasma cleanability, tunable surface hydrophobicity and the ability to analyze for nitrogen, oxygen and carbon without background signals.
  • Porous 15 nm thick UltraSM TEM Windows are just like the films listed above, but have numerous 10-50 nm diameter pores to suspend nanomaterials for imaging or growth. The polycrystaline structure provides an internal sizing and diffraction pattern calibration standard as well.
  • Silicon Nitride 20 & 50 nm thick TEM Windows are our most robust, flat and hydrophilic substrates for demanding sample preparation procedures.
  • Silicon Oxide 20 & 40 nm thick TEM windows offer an ideal surface for high-temperature nanomaterial growth of specimens.

 

MEMBRANES FOR CELL IMAGING

·         The UltraSM® silicon membrane provides a first-in-class combination of imaging and cell growth abilities for optical and electron microscopy.  This ultrathin membrane permits imaging of cells by either light, fluorescent or electron microscopic methods.  The millions of nanopores within the membranes allow two cell types on either side of the membrane to communicate with one another.  The cells can be physically separated and imaged by optical means due to the excellent optical characteristics of the UltraSM® membrane.  Together, these properties make the UltraSM® silicon membrane an ideal substrate for growth and imaging of single or multiple cell-type cultures.
