SPM Calibration Standards by NANO-S Biotechnology are the smallest artificial 2-D lateral pitch structures available on the market. Closing the dimensional gap between atomic scale and photolithographic structures, NANO-S SPM Calibration Standards offer an ideal calibration measure in the (bio)molecular range.

NANO-S Calibration Standard Structures consist of 2-dimensional protein crystals, so-called S-layers, which are self-assembled on polished silicon or glass substrates. The pitch of the resulting calibration grids is dependent on the type of S-layer used.
