Graphene Oxide on Holey Carbon, Cu Grid, 300 mesh

Graphene Oxide (GO) support film is a super thin (<1nm), naturally hydrophilic layer placed over the Holey, Lacey or Quantifoil support film on copper or gold grids. 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.

Features

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
Nearly transparent in electron beam
Barely visible under optical microscopes
Regular batch checking ensures correct coverage of monolayers
