Grids, graphene oxide on Quantifoil R1.2/1.3

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
