Carbon Core High-Aspect Ratio Carbon Nanotube AFM Probes

Carbon Design Innovations (CDI) can attach our carbon nanotubes (CNT) to almost any cantilever or substrate. Our unique/patented processes then straighten the CNT and set the desired angle for the best possible imaging performance. CNT structures longer than 500nm are re-enforced towards the base of the CNT using a proprietary coating process to ensure proper rigidity. Our multi-walled CNT (MWCNT) probes are very tough, durable and long lasting. Given that all of our probes are perfectly straight and perfectly aligned, you will get many great images from any of our MWCNT probe products…Guaranteed or your money refunded.

Our standard cantilever is based on the ANSCM-PT (~60KHz) by Applied Nanostructures. Our procedures do not alter the characteristics of the cantilever. (Please refer to Applied Nanostructures specifications for more details on the cantilever.) If you prefer a different cantilever, please contact us at info@cdi-nano.com.

tip 8

CCHR – Carbon Core High Resolution probe.

  • Designed for accurate high resolution (non-contact) imaging of structures exhibiting topographical features of less than 20nm in Z-dimension.
  • Multi-walled CNT probe is nominally 20nm diameter.
  • The effective radius of curvature of the tip is nominally 5nm (unsharpened).
  • Typical length of the exposed CNT portion of the tip is between 20nm to 200nm.
  • Overall length of the CNT, including coated CNT portion, is <500nm.
  • Aspect ratio > 5:1. Angular displacement nominally 0º
Tip 9

CCHAR – Carbon Core High Aspect Ratio probe.

  • Designed for accurate high resolution (non-contact) imaging of structures exhibiting topographical features of less than 500nm in Z-dimension.
  • Multi-walled CNT probe is nominally 25nm in diameter.
  • The effective radius of curvature of the tip is nominally 10nm (unsharpened).
  • Typical length of the exposed CNT portion of the tip is < 500nm.
  • Overall length of the CNT, including coated CNT portion, is <1.2 microns
  • Aspect ratio > 10:1. Angular displacement nominally 0º
Tip 10

CCB – Carbon Core Bio-probe (Extreme High Aspect Ratio).

  • Designed for (non-contact) imaging of structures exhibiting extreme topographical features of several microns in Z-dimension.
  • Multi-walled CNT probe is nominally 30nm in diameter.
  • The effective radius of curvature of the tip is nominally 20nm (unsharpened).
  • Typical length of the exposed CNT portion of the tip is < 500nm
  • Overall length of the CNT, including coated CNT portion, is 2 microns to >4 microns.
  • Aspect ratio > 15:1. Angular displacement nominally 0º
Tip 11

Single Walled Composite probe.

The SEM image to the left is taken of a preliminary prototype single walled carbon nanotube (SWCNT) composite probe. Composite meaning that a group of single walled CNTs were straightened then coated to ensure rigidity. The longest SWCNT forms the tip, which will consist of 2 or less SWCNTs. The SWCNT product is not ready for release and the exact specifications are not determined.

 

CDI is working on a number of additional CNT AFM probe products.
