DLC Probes

Super Sharp Diamond-Like Carbon (DLC) Probes

K-Tek Nanotechnolgy’s line of Super Sharp Diamond-Like Carbon (DLC) probes are extremely useful for obtaining high-resolution on objects only several nanometers in size. This exclusive series gives our customers superior imaging quality, and a probe with superior material durability. Super Sharp DLC probes are rigorously tested to ensure that each batch performs under strict testing situations.

Product Details

Super sharp diamond-like carbon (DLC) tips* with typical curvature radius 1nm are extremely useful for obtaining high resolution on objects with sizes of several nanometers. DLC tips have very long lifetime due to the high material durability.

To guarantee 20nm working length of DLC tips TEM is used. 10% from total number of probes in the batch are selected for testing. At least 80% of those probes should have the only DLC tip which lengh is exceeded by 20nm others DLC tips on the same probe. In this case the whole batch is considered as passed the TEM test. On the surfaces with roughness bigger than 20nm double images are possible. 

* – DLC tips can be grown on any other probe series by request

SPM image of DNA deposited on HOPG is obtained by DLC tip.
DNA size (2-2.5nm) is nearly equal to the real size (~2nm).
Standard probes provide DNA imaging with size about 10-15nm.
