The new standard for nanoscale imaging in aqueous environments
The integration of the SICM and Park NX10 AFM system from Park Systems allows researchers to expand the depth of their research and easily perform nanoscale imaging in aqueous environments.
You can the advantages of SICM head also on NX10 AFM.
Park SICM Technology. Truly non-invasive in-liquid imaging with SICM
- Park SICM uses nanopipettes
In Scanning Ion Conductance Microscopy developed by Park Systems (Park SICM), a glass nanopipette filled with an electrolyte acts as an ion sensor that provides feedback on its location relative to a sample completely immersed in liquid. The pipette tip maintains its distance from the sample by keeping the ionic current constant. In comparison, AFM typically relies on interaction of forces between its probe tip and the sample. The pipette has an inner diameter about 100 nanometers, made of glass.
- No Force, Non-Contact imaging in Liquid
The Park SICM operates in liquid without making physical contact with the sample. Electrodes on either side of the sample and pipette produce ionic current that flows through the surrounding solution. A sensor measures the current flow, which decreases as the distance between the pipette and sample becomes smaller, and monitors the distance between the pipette and the sample to obtain the topology.
- Automation for easier scanning
- Steady pipette probe-sample distance control in nanoscale
By automatically refreshing its reference value before approaching each pixel, the stopping height of the pipette near the sample surface is not influenced by set-point drift.
- Current-Distance(I-D) Spectroscopy
Acquiring Current-Distance Curve of SICM on the way of pipette approach (vertical direction movement) toward sample surface is beneficial to elucidate various biological and chemical phenomena in aqueous environment. Acquiriring the current-distance curve at multiple positions so that the researcher can reach to a deeper level understanding for biological and chemical reaction research.
