The OLYMPUS BL-AC40TS series AFM probes, also known as ‘BioLever mini’ with a sharp silicon AFM tip on a silicon nitride cantilever are designed for high resolution measurements in liquids for studying bio molecules, DNA strands, etc. The AFM tip has a two-layer structure with a tetrahedral base and an additionally sharpened top section with higher aspect ratio than conventional pyramidal AFM tips.
The OLYMPUS BL-AC40TS feature an AFM cantilever with a high nominal resonance frequency of 110kHz in air and 25kHz in liquid and a nominal force constant of 0.1N/m. An AFM cantilever with a high resonance frequency can acquire images with faster scanning speeds in AC / tapping mode measurements, reducing the time required for large area scans when searching for the site of interest.
The short AFM cantilever offers high sensitivity for force-curve measurements in liquids. With its small area it responds quickly to shape changes of bio-molecules with a short relaxation time. Additionally, it offers lower noise levels in the thermal vibration spectrum.
The holder chip does not feature alignment grooves.
