Fabrication only does not make the Nano-science Instruments polished, thus cleaning should also be done to ensure that the instrument are free of contamination. Tips that are fabricated using the electrochemical etching need to be cleaned procedurally to ensure that the contaminants caused by the fabricant treatment are removed. It is therefore important to note that rinsing them in plain water does not do the job. There are some treatment that need to be induced into the cleaning process. This article expounds further on solid metal afm probe tips.
There are several methods used to clean tips and one of them is annealing. To be able to clean tip well it is advisable to remove the impurity and the oxide layer. This tip is first heated in a chamber at a raised temperature which gradually desorbs the tainted layer. Annealing ensures that the tip is smoothen as it heals the crystallographic defect that are produced during fabrication.
Another use of the tips is to quantify intermolecular dynamisms as well as determine biochemical functionality. Single wall carbon nanotube can be used for chemically imaging with great horizontal tenacity and to study binding energy in biochemical and organic system. There are other tips that are functionalized with either hydrophilic or hydrophobic particles that are used to determine the bonding agent interrelation amid hydrophobic to hydrophobic.
As aforementioned there are different ways used to investigate the efficacy of tip. One is optical microscopy which determines whether tip actually is bent. If tip is bent the capability of detection is reduced. Optical microscopy is however regarded time consuming considering the inevitability of observing the wear or the degradation of tip by the impact of the surface after every scan.
In this account it is important to note that fabrication methods in general fall in two categorizations. The mechanical fabrication and the physiochemical fabrication. During the early phases of development of the metallic pointers, the mechanical procedures were common as they eased the fabrication process. Therefore, they were regularly used in the process.
Tips that are silicon grounded cannot be controlled effortlessly as they inhibit the silanol group. The silanol group is hydrophilic thus, it is very much likely to be susceptible to environmental pollutants. The silicon based devices also wear and tear much faster than other types of tips, for that reason it is important that they be coated
An undercoat ensures that tip does not deteriorate plus the appearance quality is equally enhanced with the covering of the surface. Coating the tip requires that the first layer be pasted which is typically chromium then through vapor deposition the gold is deposited.
It is important to note that in as much as coating is effective for silicon based devices, sometimes the tips become ineffectual as they lose tunnel uncovering proficiency thus they can no longer be used. Experts recommend that if coating is to be done then it must ensure that the detection properties are not tampered with.
