DRASTIC CHANGES IN MEDICAL FIELD BY THE INVENTION OF NANOBOTS

Nanorobot (nanobots, nanoids, nanites) is a small electromechanical device with an exterior made up of carbon atoms in a diamond shape is used to interact with nanoscale objects or manipulate with nanoscale resolution. Usually the size of these robots range from 500-3000nm. In surgery this is more accurate instead of using the human hand. Nanobots moves around their environment consuming molecules to attain energy. Nanobots direct themselves towards certain cells by their glycolipid structures. This idea would help physicians to treat diseases effectively without any adverse side-effects, actually the idea is to repair organs

A REVIEW ON DNA NANOBOTS – A NEW TECHNIQUE FOR CANCER TREATMENT

Cancer is one of the deadliest diseases of this century. Tedious and painful radiation therapy and chemotherapy are administered using many drugs including antitumor antibiotics, which cause a lot of side effects. As an alternate, DNA nanorobots serve as a potential cancer treatment technique which is very much safer than other therapies and acts specifically as well. DNA nanobots are said to set a new milestone in the development of medical studies. The primary objective of this bot is to target and eliminate cancer cells from the human body. These bots are made of a single strand of DNA folded into the desired shape. The bots will have two states - an off†position, where the clamshells are closed tightly to bypass healthy cells without any damage and an on†position, where the clamshell opens up to expose cancerous cells to the drug so that the drug can do its job to eliminate the cancer cell. This novel idea will be actively used within the public when it passes its first human trial. In this review, we focus on eliminating cancer cells. Since the bot can be programmed and is capable enough to carry a payload, it can also be used to cure any other diseases as a secondary target. Creation of nanobots has been under progress already and may come within the public after an estimated time of 5 years

P1_9_Powering_Nanobots_with_Body_Heat

This article discusses the feasibility of using variations in the human body temperature to power a medical nanobot. It is found that thermal energy gained from a Carnot cycle process is not sufficient to power a typical nanobot. A typical medical nanobot requires 1x10-9W, the model outlined here finds that the maximum power a nanorobot can gain is 5.7x10-17W. Under normal circumstances the power gain is only 2x1016W. Thus it is concluded that this process is not sufficient to act as the sole power source for such a nanorobot

Enzyme-powered nanobots enhance anticancer drug delivery

The use of enzyme catalysis to power micro- and nanomotors exploiting biocompatible fuels has opened new ventures for biomedical applications such as the active transport and delivery of specific drugs to the site of interest. Here, urease-powered nanomotors (nanobots) for doxorubicin (Dox) anticancer drug loading, release, and efficient delivery to cells are presented. These mesoporous silica-based core-shell nanobots are able to self-propel in ionic media, as confirmed by optical tracking and dynamic light scattering analysis. A four-fold increase in drug release is achieved by nanobots after 6 h compared to their passive counterparts. Furthermore, the use of Dox-loaded nanobots presents an enhanced anticancer efficiency toward HeLa cells, which arises from a synergistic effect of the enhanced drug release and the ammonia produced at high concentrations of urea substrate. A higher content of Dox inside HeLa cells is detected after 1, 4, 6, and 24 h incubation with active nanobots compared to passive Dox-loaded nanoparticles. The improvement in drug delivery efficiency achieved by enzyme-powered nanobots may hold potential toward their use in future biomedical applications such as the substrate-triggered release of drugs in target locations

Shepherding Electric Sheep: A Roman Catholic Response to the Emerging Challenge of Transhumanism

Transhumanism is a philosophical, political, and social movement that asserts that human well-being will be dramatically improved through the radical integration of new technologies into the human body and/or through the replacement of the organic human body with a synthetic \u27body.\u27 Ray Kurzweil, a dynamic, articulate, and leading transhumanist, offers an anthropological understanding that represents the main strand of transhumanist though about the human person: humans are patterns of information that can adjust themselves, and overcoming limitations is the defining human characteristic. This anthropology is implicit in many aspects of Western civilization already: law, medicine, and the military are a few examples of where it currently exists. This anthropology is attractive to modern people because of its promise of self-enhancement, but it is dangerous because it objectifies the human person, especially the body. The Roman Catholic Church\u27s anthropology, as explained in the document Gaudium et spes, offers a more authentic understanding of the human person, and the Church must act now to share its anthropology with both Catholics and non-Catholics in order to better fulfill its mission
