Nanotechnologies lend a helping hand to handicapped individuals

Nanotechnology has a great impact in today’s world. One of the most curious and promising field in medicine is tissue regeneration. Doctors have practiced tissue regeneration for many years ago, however, the list of already created organs extended with a new item. Wisconsin University is famous for their brilliant achievements in medicine. So, scientists from there have studied the way of creating vocal cords from several donated cells.

Dr. Nathan Velham has found a tissue that could be appropriate for the mucous membrane of the vocal cords, which is represented by two petals ligaments. Namely, this tissue allows you to produce a vibrating human speech without transplantation them from another body. These unnatural vocal cords are made from donor cells of five volunteer patients. During two weeks, scientists and lab worker were growing tissue under appropriate conditions. Then, these cells added to an artificial larynx layout.

It comes as no surprise that produced voice will not sound completely natural because of artificial vocal cords. By and large, the produced voice resembles metal sound in labs condition. However, scientists strongly believe that if these vocal cords implant into the human body, they will sound almost like the real voice.

As the matter of fact that pretended cords could reject by a human body, the vast majority of scientists consider that it would not happen. In one recent experiment that took place regarding immune system, it was decided to test laboratory mice whether their body will reject or accept the new tissue. Fortunately, rodents accept it without any harmful outcomes. Dr. Velham hopes that the experimental tissue will not be rejected by the human body also.

Not only vocal cords are important to live the fullest life, but also eyes, which are also, for example, prone to photo-degeneration of retina. Without a doubt, there are the vast majority of people who affected by so-called Retinitis Pigmentosa. The problem is that there is no remedy for such patients and it contributes not only to disadvantages of appearance, but also to some physiological problems. Luckily, solution was found out. So as far as is known, nanoscope scientists have developed such appliance as Multi-Characteristics Opsin, which is pretty photoactive, that let stimulate retinal cells in order to renovate the vision. Nano scopes could treat the most difficult eye’s diseases and for the first time, they elaborate and carry out the fastest laser which supposes to renew the vision of blind animals. By the way, nanoscopes are also really useful in detecting the diseases on the cell level. As for advanced and high-quality optical nano scope of LIG technologies – it has shown excellent results in testing among the other latest tools.

Summing up, it worth saying that it is brilliant idea that nanotechnologies do not forget about people with specific purposes. The usage of technological progress stay the right course and it must go on moving in this direction. It is sort of vital that Universe has chosen researchers and scientists to fulfill someone’s prayers.
