TEM Grids with Ultrathin Film
Overlay of ultrathin (~3 nm) film on holey supporting film, to hold nanoparticles but have minimum background inteference
Description
🔹 Description
These TEM grids consist of an ultrathin continuous carbon film deposited on a holey carbon or Formvar support film, forming a multilayer structure that combines high transparency with sufficient mechanical strength.
The ultrathin carbon layer (~3–5 nm) provides excellent electron transparency and minimal background interference, making it ideal for high-resolution imaging of nanoscale materials.
