Nanotechnology: Top Down and Bottom Up to Nanotechnology - Essay Example

Currently, employment and advancement have taken their toll on the top-down method. It can be said that the other approach namely the bottom-up approach is still in its theoretical phase. There is much need for advancement in the applied approach of bottom-up.

It is due to their reason that nanotechnologists have made use of self-assembly as a better way to fabricate and manufacture different devices. The technological progress however can be considered as less towards the bottom-up approach of manufacturing (Bhushan 2007). There is Plenty of Room at the Bottom- Article Summary: The lecture by Richard Feynman turned out to be the base for one of the most critical approaches to nanotechnology. As per the lecture, it was possible to manipulate materials.

This was possible due to the observation of matter with the help of atomic scale. The lecture was directed towards the exploration possibility of creating computers much smaller in size. Most importantly, Feynman focused on the creation of telescopes that were quite smaller in size in comparison with the other electron microscopes. He also stressed the fact that humans must be able to create machines that can perform actions with the structuring of atoms in a series the way humans want. The reference to the conception of atomic arrangement was given through the aid of machines like scanning probe microscopy, Millipede, etc (Binns 2010).

In the lecture Fey,nman also highlighted the fact that humans need machines that can perform with the atomic arrangement which will be further interpreted or manipulated with the help of mechanical formalization. One of the interesting aspects of his lecture was the creation of a small swallowable robot (Feynman 1960). This was put in a working schema by providing the user with a one-quarter-scale manipulator and. On further discussion, it also came to understanding through Feynman’s lecture that the analogy of pantograph can help in scaling down the items.

The fact remains that as the machine shrunk in terms of design so the ability changes as well which needs address by designers because the force of the machine to perform operations changes with the energy (Steed and Atwood 2009). Intrinsic top-down unmanufacturability- Article Summary: Kelly (2011) in his article considered the analogy of fabrication about manufacturing. The changes that can be brought to a machine can be in terms of lithography, repositioning of the structure, etc. In the article, the author has notified that with the usage of a top-down approach, it is impossible to create fabrication of a 3nm design.
