Atomic-force microscopy

PML’s new Single Cell genomics facility features the world’s fastest High-Speed Atomic Force Microscope (HS-AFM). The Mk4 system, developed by GW4+ partners at Bristol University and Bristol NanoDynamics, is capable of recording at up to 24 million pixels per second and can carry out over a years’ worth of conventional AFM imaging in just a few hours. Providing nanometre resolution for imaging millimetre sized areas or real-time videos of dynamic nano or micro scale structures or surface processes, the HS-AFM will revolutionise the study of environmental organisms.

Making use of newly-discovered physics, our contact mode high-speed atomic force microscope (HS-AFM) is the fastest in the world by several orders of magnitude.

The HS-AFM moves the sample in a raster pattern and engages a sharp tip with the surface to map sample topography with nanometre lateral and sub-atomic height resolution over millimetre-sized areas.

The tip can be thought of as a finger passing across a surface, able to map both the height of the surface and the local stiffness, thermal and electrical properties at the same time.

The microscope doesn't require either the sample to be conductive or a vacuum to operate; indeed, it is able to image samples in gaseous and liquid environments.
