Probes more cost effective than standard ones

OUR TECHNOLOGY

Our technology is based on the coating of AFM tips with nanoparticles of controlled size and chemical composition. The nanoparticles are deposited along the tip side of the cantilever.

The nanoparticles deposited at the end of the tips do act as the final probes in microscopy, enhancing the spatial resolution with the intrinsic physical and chemical properties of the nanoparticles.

Next-Tip technology offers SuperSharp resolution with enhanced lifetime, as it avoids the fragility of standard SuperSharp tips. Making our probes more cost effective than standard ones.

REGENERATIVE FEATURES

The nanoparticle coating provides great competitive advantages to Next Tip probes.

Thanks to the unique characteristics of our technology, the tips can be regenerated during the scanning process.

  • This property avoid unproductive wastes of time (Tip substitution and the location of the sample).
  • Increasing the effective work and concentration of the technicians.
  • Multiplies the lifetime of the tips by a factor of approximately 5 (very convenient for low temperature, high vacuum or any application where the replacement of the tip is not straightforward).
regenerative

Regeneration Process Briefing:

  1. Find a smooth region on your sample (if your sample is very rough is better to put a flat surface like mica or Si wafer).
  2. Scan a small area and press progressively the tip towards the sample at small steps until the amplitude is reduced to ~ 20% A0.
  3. Leave it scanning for a few seconds and lift it slowly until the setpoint amplitude is recovered.

HIGH RESOLUTION FEATURES

The great control of the coating process allows high resolution on robust probes with a high degree of reproducibility. The nanoparticle coating provides a great stability to our probes. Thanks to the unique characteristics of our technology, the tips can be regenerated, presenting a lifetime significantly longer than other probes.

We offer products for high resolution in topography (NT-TP), for electric characterization (NT-CD series) and during 2018 we will release our unique probes for TERS.
