Learn all about nanobots and nanotechnology and its medical applications.
Today the field of nanotechnology is on the verge of many breakthroughs that may change medicine, science, and engineering as we know it. Can you imagine being able to cure cancer by injecting nanotechnology that has been programmed to eliminate specific cells? That could be our future world.
Nanotechnology in medicine involves applications of nanoparticles currently under development research that involves the use of manufactured nano-robots to make repairs at the cellular level.
With the advent of nanotechnology, the prospects for using engineered nanomaterials with diameters of < 100 nm in industrial applications, medical imaging, disease diagnoses, drug delivery, cancer treatment, gene therapy, and other areas have progressed rapidly. The potential for nanoparticles (NPs) in these areas is infinite, with novel new applications constantly being explored. The possible toxic health effects of these NPs associated with human exposure are unknown.
This remarkable technology promises huge advances in extending healthy lifespan, and is not limited to Freitas’ efforts. Other nanorobot research underway, include University of Southern California; Cornell University; Monash University; and Ecole Polytechnique, Montreal. It’s the dream of most future watchers, including this writer, that we will one day say goodbye to aging, hello to being forever young and healthy.
Nanobots and Nanotechnology Medical Applications
Nanobots and nanotechnology medical applications are;
Using nanomachines to deliver drugs to specific locations in the body could be more effective than consuming pharmaceutical drugs or injecting drugs into the body. Nanites or nanobots could be used to absorb toxins and remove these toxins from organs and the bloodstream.
Scientists have found that some nanomaterials have the ability to detect certain drugs and nutrients.
Nanomachines could be equipped with DNA or certain healing chemicals to heal damaged cells and tissues. As the cells and tissues are healed, it makes it easier for the body to recover from injuries. Surgical nanorobots are introduced into the human body through vascular systems and other cavities. Surgical nanorobots act as semi-autonomous on-site surgeon inside the human body and are programmed.
What is Nanotechnology for Medical Use?
Nanotechnology is the study of extremely small structures, having size of 0.1 to 100 nm. Nano medicine is a relatively new field of science and technology. Nano particles are used in drug delivery, protein and peptide delivery. Also nano systems in cancer therapy are used as carbon nano tube, dendrimers, nano crystal, nano wire, nano shells etc. The advancement in nano technology helps in the treatment of neuro degenerative disorders such as Parkinson’s disease and Alzheimer’s disease. Nano technology is also used in tuberculosis treatment, operative dentistry, in ophthalmology, in surgery, visualization, tissue engineering, antibiotic resistance and immune response. Nano pharmaceuticals can be used to detect diseases at much earlier stages.
Are Nanobots real?
Nanobots can be considered to be machine version of a bacteria or virus. They can be biological or synthetic, but are adapted to perform preprogrammed tasks at the atomic level. They are expected to be autonomous in nature and powered by a small cell or battery, or even solar cells.
A nanorobot is a tiny machine designed to perform a specific task or tasks repeatedly and with precision at nanoscale dimensions. Nanorobots have potential applications in the assembly and maintenance of sophisticated systems. Nanorobots might function at the atomic or molecular level to build devices, machines, or circuits, a process known as molecular manufacturing.
How small is a nanobot?
Nanorobots are so small that they actually interact on the same level as bacteria and viruses. Nanorobots or nanobots are measured in nanometers or a millionth of a millimeter. Nanorobots (nanobots or nanoids) are typically devices ranging in size from 0.1-10 micrometres.
What are Nanobots made out of?
Traditionally, most robots have a solar cell or some kind of battery pack, but obviously these are many times too large for nanobot. However, the answer may lie in nuclear technology. Researchers consider it highly likely that when equipped with a thin film of radioactive material, nanobots will be able to fuel themselves on particles released by decaying atoms.
How are Nanobots made?
Nanobots could be made from carbon nanotubes, a new type of carbon. To build the 4-nm-diameter molecular robot, the researchers started with a common protein called streptavidin, which has four symmetrically placed binding pockets for a chemical moiety called biotin. Each robot leg is a short biotin-labeled strand of DNA, “so this way we can bind up to four legs to the body of our robot,” Walter says. “It’s a four-legged spider,” quips Stojanovic. Three of the legs are made of enzymatic DNA, which is DNA that binds to and cuts a particular sequence of DNA. The spider also is outfitted with a “start strand” the fourth leg that tethers the spider to the start site (one particular oligonucleotide on the DNA origami track).
How Nanobots work?
The nanorobot will be travelling through the bloodstream to reach its target. The blood contains a number of charged particles in it, which if used in the right way, could form a battery for the nanorobot. The nanorobot could be equipped with electrodes, and with the help of these electrodes and the electrolytes in the surrounding bloodstream, a suitable power source could be created. Another option is to provide the nanorobot with a host of chemicals that would burn when they react with blood. The energy released by the combustion would then provide the nanorobot with the needed power.
Applications such as closing open wounds, rebuilding ruptured arteries and veins and traversing through the body for diagnoses are some important realizations. They are expected to aid in research related to cancer, AIDS and other major diseases as well as in helping brain, heart and diabetes research. Other applications where nanobots can potentially be of use are in aerospace, security, defense, electronics and environmental protection. Nanobot’s applications are;
Respirocytes are hypothetical nanobots engineered to function as artificial red blood cells. Nanobots with embedded chemical sensors can be designed to detect tumor cells in the body. Nanorobots will also have useful applications for biohazard defense, including improving the response to epidemic disease.Genetic disease can be treated by nanorobots
Scientists have long said that tiny robots would soon be able to conduct surgery and deliver drugs deep inside the body. The field of medicine is expected to receive the largest improvement from this technology. This is because nanotechnology provides the advantage of transporting large amounts of nanorobots in a single injection.
Tiny ‘walking’ nanobots made from DNA could roam around inside the body and deliver medicine to where it’s needed. Throughout the patient’s body, the tiny robots home in on red blood cells, binding only to those that are infected, ignoring the healthy blood cells nearby. Then, one by one, they punch holes in the membranes of the infected cells, injecting a powerful drug that dispatches the parasites within. Later the body breaks down the nanorobots themselves, which are made entirely of DNA, into harmless byproducts, and the body safely excretes them.
Nanobots cancer Treatment
Cancer survival rates could be greatly improved if scientists are successful in developing microscopic medical weapons that obliterate cancerous cells. These minute molecules have components that enable them to identify and attach themselves to a cancer cell. When activated by light, the nanobots’ rota-like chain of atoms begin to spin at an incredible rate around two to three million times per second. This causes the nanobot to drill into the cancer cell, blasting it open.
Self Replicating Nanobots
Self-replicating tiny robots could completely consume all life on Earth and lead to the end of the planet, experts have warned. Nanobots, which are theoretical tiny robots a single nanometre wide one billionth of a metre are currently being worked on and in the future may dominate the planet if they get out of control. A good argument about the eventually possibility of the “grey goo” scenario is that self-replicating nanobots do not have the potential to replicate at all.
Nanobots in Blood Pros and Cons
New storm walls and levies could be built passively instead of actively. Health care could become cheaper and more effective. Instead of invasive surgeries, nanotechnology could repair organ damage with one basic injection. As time goes on and technology advances, medicine has to advance with it. Modern medicine is looking to produce small nanobots that can be placed within the bloodstream to many things medicine cannot do outside of the body. The human body has a remarkable ability to respond to invaders. Nanotechnology would be considered an invader and white blood cells could attack the tech suppressing the immune system or nanotech encounters with WBCs could have unforeseeable and unintended consequences.
Nanobots Clinical Trials by 2020
Nanorobots radical science in clinical trials by the 2020s; expert says, the nanorobots are already designed and created and will likely be in clinical trials at the major healthcare institutions in the early 20s.
