You hardly imagine how the world could be tiny as well as giant at the same time. This opportunity is available for you with the recent nanotechnologies. On the scale of meters, our perception of life has some particular meaning and size and it is sort of impossible and impressive to penetrate and plunge in another dimension that is smaller than insect’s eye.
If you think that nanotechnology is modern concept, you a bit mistaken. It dates bake to the beginning of XX century when eminent Richard Feynman, who was American physicist, was credited with his raised interest in nanotechnology. However the heyday of nanoscience is estimated in the 1980s. Many books were published regarding this topic and they were really popular not only with scientists, but also among lay readers. Nowadays, new approaches are being developed by scientists, allow literally see the amazing molecular world, observe the complex organic molecules and the growth of crystals in atomic resolution, viruses and living tiny organisms.
Have you ever asked yourself, how small our world is at the nanoscale level? The thing is that the smallest bacterium has a length of about 200 nm, helically twisted double stranded DNA molecule is about two nanometers in diameter, and the distance between atoms in carbon materials is only 0.15 nm. It is obvious kind of hard to understand these dimensions because of its small quantity and our mistrust due to the fact that we could not see these viruses, cells and batteries. The importance of nanoscope should not be underestimated because it cares about our life, health and progress. In addition, modern science opens the possibilities of nano-tools in many technological spheres. Meanwhile, it has become increasingly important to challenge them in order to see whether the nanotools with high resolution as nanoscopes of LIG Tech could be useful. This idea was carefully checked by scientists, who have found two effective approaches that allow see materials at the atomic and molecular resolution. They are called scanning electron microscopy and atomic force microscopy.
As far as atomic force microscopy is concerned, it does not require a vacuum. Furthermore, with its help living biological objects can be studied. This method is widely used in the last 20 years. The problem is that such method has two serious drawbacks. The first one is time-consumption of different procedures and next is roughness of scanning device, which could probably damage some fragile samples. However, Mervyn Miles, who is a professor in the field of nanoscale physics of the Physics Department at Bristol University, has found the opportunity to figure out this problem. Miles suggested looking at that problem from the other side. So, instead of reducing the size of scanning tool, there was developed material for the top which is supposed to be with increased sensitiveness. In such a simple way, you could obtain one image in 50 seconds comparing with another tool that took so much time and damaged the sample. In real time, it is allowed to create a video image, and give the opportunity to monitor the process of crystal growth in the nano-world.
