Exposed End Ultra Sharp NeedleProbe (EEUSNP)
NaugaNeedles introduces a new exposed end nano-electrodes on their USNPTM probes. The basic structure of these probes is the tungsten probe with a high aspect ratio Nanoneedle. The entire probe is sealed with Parylene and exposed at the very end of the Nanoneedle and exchanged with platinum. To avoid any possible leakage a heat-shrink and epoxy is covering the trunk of the tungsten probe. These probes make it possible to perform transport measurement by a nano-electrode (the platinum tip) under liquid. They are easy to mount in different manipulator, probe station and STM.
