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 (see the details here).
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
