Needleprobes or Specialized AFM probes
NaugaNeedles probes are built around our proprietary method of securely attaching long, flexible and durable metal nanoneedles onto AFM cantilevers and tips. The shape and high conductivity of the needles provides a wide range of enhanced sensing and manipulation capabilities. The needles can be functionalized in many ways by NaugaNeedles to further extend their applications. Specialized AFM probes are made by growing metallic nanoneedles at the end of AFM probes and by selectively coating the needles with other chemical to activate the probes.
NaugaNeedles' Ultra Sharp NanoProbe (USNP)
NaugaNeedles has developed a very unique nanofabrication technology to selectively grow individual metallic Silver/Gallium (Ag2Ga) nanoneedles at the end of standard tungsten probes. The Ag2Ga nanoneedles have superior electrical, mechanical and chemical stability that significantly improve the performance of Micro-Probe-Stations and Nano-Manipulators. Figure 1 shows SEM images of an ultra sharp NanoProbe (USNP). A 5 μm long and 60 nm diameter Ag2Ga nanoneedles is grown on a standard tungsten probe, with a radius of curvature of ~ 13 nm at the tip. The nanoneedles is attached to the tungsten probe by a taper shape structure made of Ag2Ga alloy, that significantly enhances the mechanical stability of the nanoneedle.
