Nanonics produces a variety of glass insulated nanowires. New worlds of research have been opened up by these unique AFM sensors, which include:
- The first normal force sensing probes for Scanning Electrochemical Microscopy (SECM).
- The first shielded STM probes that can provide combined AFM and STM.
- AFM sensing thermocouples with the highest sensitivity and resolution available today.

100x100µm SEM of Thermocouple
Probe with 200nm tip |
With these new probes, capacitance measurements of surfaces without oxide coatings are possible for the first time. Such shielded metal nanowires also make impedance microscopy a reality.
