TEM imaging of unstained DNA nanostructures using suspended graphene
Abstract
We demonstrate a method for imaging unstained DNA nanostructures with transmission electron microscopy via suspended graphene supports. Central to the technique is a sacrificial silicon membrane beneath the graphene that provides mechanical support during aqueous sample deposition but is then eliminated in a final step using a XeF2 dry etch.
