NANOSENSORS™ qp-BioAC AFM probes are designed for mainly dynamic mode AFM imaging in air or liquid environments, but can also be used in contact mode. These AFM probes feature three different rectangular AFM cantilevers on one side of the support chip. The uniqprobe BioAC type unites fairly high resonance frequencies with low force constants. The combination of these characteristics leads to stable, low noise and fast measurements with reduced AFM tip-sample interaction.
