Imaging a single protein has been a long-standing dream for advancing structural biology and with this various fields in natural science. Here I will show that, sub-nanometer resolved images of individual folded proteins have been obtained for the first time ever. Electrospray ionization for the specific selection and sound deposition of individual proteins onto ultraclean freestanding graphene in an ultra-high vacuum environment and low-energy electron holography for the non-destructive imaging are combined in a novel experimental workflow.
