AFM tips from Next-Tip have been coated with a special layer of nanoparticles with controlled size that allows High-Resolution mapping in both topography and Kelvin probe in dynamic modes.

HIGH RESOLUTION REGENERATIVE TIPS FOR AFM TAPPING/NON-CONTACT MODE MAPPING IN TOPOGRAPHY

PRODUCT DESCRIPTION

NT-TP- HRES Tips allow High-Resolution mapping in topography.

Thanks to the small size of the end of the tip (2 Nm), enhanced lateral resolution is achieved (usually the lateral resolution is enhanced by 30%).

Also the Next-Tip Probes can be regenerated following our tested procedure that multiplies the lifetime of the tips by a factor of approximately 5 (very convenient for low temperature, high vacuum or any application where the substitution of the tip is not straightforward).

APPLICATIONS

These AFM tips can be used in a wide range of disciplines: including solid-state physics, materials science (polymer chemistry, ceramics, metals…), semiconductor technology, biology, surface chemistry and medicine.

CONDUCTIVE REGENERATIVE TIPS

PRODUCT DESCRIPTION

Thanks to the small size of the end of the tip (2 nm), enhanced lateral resolution is achieved (usually the lateral resolution is enhanced by 30%). This mapping resolution is achieved while measuring surface potential.

Also the Next-Tip Probes can be regenerated following our tested procedure that multiplies the lifetime of the tips by a factor of approximately 5 (very convenient for low temperature, high vacuum or any application where the substitution of the tip is not straightforward).

APPLICATIONS

Next Tip electrically conductive proves have a gold coated tip, that is the best choice for electrical characterization applications such as Kelvin Probe Force Microscopy (KPFM), Scanning Capacitance Microscopy (SCM), Electrical Force Microscopy (EFM).

ADDITIONAL INFORMATION FOR CONDUCTIVE TIPS USERS:

  • Put some silver paint to attach the tip to the holder to ensure the electrical conductivity.
  • Use low scan frequencies and low excitation frequencies.
  • The best performance of the NT-CD tips are obtained in Frequency Modulation (FM).
  • Voltages between 0.5-2 V are usually enough for a good surface potential signal. In case of insulating substrates, voltages up to 5 V can be applied. Higher voltages are not recommended.

HIGH REALIABILITY TERS TIPS

PRODUCT DESCRIPTION

Tip-enhanced Raman Scattering (TERS) is a powerful spectroscopic technique that provides subdiffraction morphological and chemical information on sample. This method is nondestructive and combines the chemical fingerprint recognition given by Raman Spectroscopy with a nanoscale near-field resolution offers by Atomic Force Microscopy. The metal-coated tip acts as a highly localized nanoantenna that produces a surface plasmon resonance at the wavelength of interest that enhances the Raman signal. Next-Tip has developed a new high reliability TERS tips, covered by nanoparticles with a diameter ̴14 nm providing a large surface enhance Raman signal and accurate spatial resolution.

High reliability TERS tips are a potential tool for deeper analysis into the surface properties of many biosystems at the nanoscale such as, DNA, RNA, proteins or for drug delivery applications.

This tip has been used for surface analysis of the Bacilus subtilis1 spore observing the chemical distribution of this complex biological system.
