20 - 020 Making things smaller than Coronavirus 2 (SARS-CoV-2)

 Now with the latest advanced chips having digital switch sizes down to 5 nanometers (nm) you can appreciate how much progress has been made in the miniaturisation of electronics. It is worth on Wikipedia looking up the “International Technology Roadmap for Semiconductors” or ITRS to see the progress on miniaturisation from 1971 getting down to 5 nm in 2020 for the size of these digital switches.

Now you realise these digital switches are now smaller than the Coronavirus 2 Virus which has a range between 60 nanometers (nm) to a maximum diameter of 140 nanometers (nm). Whilst the length of the spikes that surround the coronavirus sphere can vary from 9 to 12 nm. So we are now able to successfully manufacture something smaller that the virus. But in both cases it is very difficult to comprehend how small both these switches and the virus are in the real world. Now both of these can be viewed using electron microscopes along with many other small pieces of matter. This is called science undertaken at a nanoscale level. The exciting aspect to viewing the world at a nanoscale level is everything in our world starts to look exactly the same. So both inorganic and organic (life supporting) structures start to look identical. At the nanoscale level we move down to seeing the smallest building blocks of our world. Importantly to this author it will start to unify all the separate sciences under the one heading of Nanosciece and its application through Nanotechnology. Nanotechnology is focussed upon using real things that measure between 1 to 100 nanometers. Without a doubt it will be information technology that proves the most effective technology for the unification of the other sciences which has evolved its own name as Nano Convergence. But before we consider this unification or convergence it is important to get an appreciation of the size of a nanometre.

A nanometer is a unit of length equal to one billionth of a meter. (0.000 000 001 m) and is used to express dimensions on an atomic scale. For example a helium atom is 0.06 nm which is a reminder that you can have many things that are even smaller than a nanometer. Now everybody appreciates a nanometer is very small but it is difficult for us to picture exactly how small. To give you some perception note a coin like a penny is roughly 1 millimeter thick so imagine you could shrink yourself down to being just 1 nanometer tall then that 1 millimeter coin sat alongside you would look like it was a 100 miles tall.

Now in the organic or living world the DNA in the cells of our bodies is between 2 to 3 nanometers thick but up to several millimetres long so it has the proportions of a long piece of fine thread curled up inside the chromosomes. Atoms and water molecules are smaller than a nanometer. Whilst the wavelength of visible light ranges from approximately 400 nanometers at the violet end of the spectrum to approximately 700 nanometers at the red end.

So in terms of the size of what we can manufacture we are not far off being able to make digital life but establishing the digital patterns that can generate the chemical patterns to make us humans it is going to require far more complex digital processing. This is where the use of Artificial Intelligence (AI) processing techniques is going to accelerate our progress.
