A propos de cet article
Graphene Oxide (GO) support film is a super thin (<1 nm), naturally hydrophilic layer placed over the Holey, Lacey or Quantifoil support film on copper or gold grids.
- Works well with Holey Carbon, Lacey Carbon and Quantifoil grid types, effectively spanning the gaps
- Less expensive to produce due to complexity of graphene manufacturing
- Better background contrast than graphene, results in higher resolution
Pre-treatment of GO Support Films is unnecessary. By default, the hydrophilic surface spreads particles evenly across the grid. A hydrophobic surface can be achieved by heating in the air. Note: plasma cleaning or glow discharge will damage the support film.
