High-quality Graphene

We utilizes chemical vapor deposition (CVD) to epitaxially grow large-area, high-quality graphene films on the copper foil and Cu(111)/sapphire wafer. This approach allows for the batch production of single-crystal, flat and clean graphene films with controllable layer.

     Increase Sample Preparation Success Rate

Graphene can effectively enhance the adsorption of biomolecules. Simultaneously, the structural denaturation and preferred orientation of protein particles, caused by air-water in terface, can be avoided to improve the success rate of sample preparation.

Graphene exhibits excellent mechanical and electrical properties, effectively suppressing particle movement caused by electron beams, significantly enhancing image quality and imaging resolution.

     Enhance Imaging Resolution

Monolayer graphene has a thickness of only 0.34 nm with negligible background noise. Additionally, graphene facilitates the preparation of uniform thin ice, providing high contrast for small proteins (<100 kDa).
