& CRYONICS AN IMPLEMENTATION OF NANOTECHNOLOGY Authorised By SANTOSH BHARADWAJ REDDY Email: Engineeringpapers.blogspot.com More Papers and Presentations available on above site Abstract: Nanotechnology is a fascinating science for many scientists as it offers them many challenges.One such challenge is Nanorobots, which once thought to be a fantasy has come into reality now.The proposed application of nanorobots can range from common cold to dreadful disease like cancer.. The study of nanorobots has lead to the field of Nanomedicine. Nanomedicine offers the prospect of powerful new tools for the treatment of human diseases and the improvement of human biological systems. Cryonics is the process of using ultra cold temperature to preserve the dead body. Molecular Nanotechnology is the best way for Cryonics.Preservation may continue for decades or centuries. Cryonic suspension is a method of stabilizing the condition of someone who is terminally ill so that they can be transported to the medical care facilities that will be available in the late 21st or 22nd century. Introduction: Representation of nano The present era of Nanotechnology has reached to a stage where scientists are able to develop programmable and externally controllable complex machines that are built at molecular level which can work inside the patient’s body. Nanotechnology will enable engineers to construct sophisticated nanorobots that can navigate the human
of nanorobots responding as fast as possible for a specific task based scenario. Nanorobot Control Design (NCD) simulator was developed, which is software for nanorobots in environments with fluids dominated by Brownian motion and viscous rather than inertial forces. First, as a point of comparison, the scientists used the nanorobots’ small Brownian motions to find the target by random search. In a second method, the nanorobots monitor for chemical concentration significantly above the background level. After detecting the signal, a nanorobot estimates the concentration gradient and moves toward higher concentrations until it reaches the target. In the third approach, nanorobots at the target release another chemical, which others use as an additional guiding signal to the target. With these signal concentrations, only nanorobots passing within a few microns of the target are likely to detect the signal. So, the nanorobot uses this information to determine when enough nanorobots are at the target, thereby terminating any additional “attractant” signal a nanorobot may be releasing. Nanorobots in Cancer Detection and Treatment The development of nanorobots may provide remarkable advances for diagnosis and treatment of cancer. Nanorobots could be a very helpful and hopeful for the therapy of patients, since current treatments like radiation therapy and chemotherapy often end up destroying more healthy cells than cancerous ones. The Nanorobots will be able to distinguish between different cell types that is the malignant and the normal cells by checking their surface antigens. Nanoparticles armed to combat cancer This is accomplished by the use of chemotactic sensors. Using chemical sensors they can be programmed to detect different levels of E-cadherin and beta-catenin in primary and metastatic phases. Medical nanorobots will then destroy these cells, and only these cells. The following control methods were considered: Random: nanorobots moving passively with the fluid reaching
targeted delivery, in performing nanosurgery. CRYONICS: WHAT IS CRYONICS?? Cryonics is the practice of preserving human bodies in extremely cold temperatures with the hope of reviving them sometime in the future. The idea is that, if someone has "died" from a disease that is incurable today, he or she can be "frozen" and then revived in the future when a cure has been discovered. A person preserved this way is said to be in cryonic suspension. Life can be stopped and restarted if its basic structure is preserved. The emerging science of nanotechnology will eventually lead to the devices capable of preserving the bodies at temperature that could stop heart, brain and other organs from functioning and recovering any preserved person in which the basic brain structures encoding memory and personality remain intact. WHY CRYONICS?? There are various modern preservative procedures available which are collectively called Cryonics. Cryonics allows carrying out a suspension before a declaration of death, preserving the maximum amount of neural information. NANOTECHNOLOGY AND CRYONICS: In the final analysis, aging and death have only one cause: for whatever reason, the atoms and molecules in our bodies have moved from their proper positions; and other molecules and atoms have moved into positions where they should not be. The molecular machinery in our bodies maintains our lives by handling molecules at the molecular level. The cell repair machines of molecular nanotechnology will not only prevent the natural causes of death, but most death by trauma as well. Artificial molecular machines can perform repairs far faster than the natural healing process. HOW IS CRYONICS PERFORMED?? If a person has to be preserved using cryonics the heart of the person should stop beating and the person should be pronounced “legally dead”. The team of cryonicists stabilizes the body,
