Welcome to Molecular Robots. Molecular Robots is another term sometimes used for nanorobotics. Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer. More specifically, nanorobotics refers to the still largely hypothetical nanotechnology engineering discipline of designing and building nanorobots, constructed of nanoscale or molecular components. As no artificial non-biological nanorobots have yet been created, they remain a hypothetical concept.
Another definition sometimes used is a robot which allows precision interactions with nanoscale objects, or can manipulate with nanoscale resolution. Following this definition even a large apparatus such as an atomic force microscope can be considered a nanorobotic instrument when configured to perform nanomanipulation. Also macroscale robots or microrobots which can move with nanoscale precision can also be considered nanorobots.
Molecular Robots are largely in the research-and-development phase, but some primitive molecular machines have been tested. An example is a sensor having a switch approximately 1.5 nanometers across, capable of counting specific molecules in a chemical sample. The first useful applications of nanomachines, if such are ever built, might be in medical technology, where they might be used to identify cancer cells and destroy them. Another potential application is the detection of toxic chemicals, and the measurement of their concentrations, in the environment.

If you have ever thought of having an acupuncture treatment but have not for fear of needles, there is no need to fear now. In a new form of treatment silicone chips are placed on the skin instead of piercing it with acupuncture needles.
How do the Silicone Chips Work?
When I first experienced the Nano chips on my skin I felt a tingling, hot sensation in each acupuncture body point where the chip rested. While the chip retained its coolness the body responded with the ebb and flow of heat and a feeling of relaxing buzz, similar to when Chi is activated with acupuncture needles. Dr. Xu, co-inventor of the Health Recovery Chips and a practitioner of acupuncture in Toronto, explained the process as the permeation of vibrational signals that flow through the designated acupuncture channels to blood, to the organs, muscles, to all the cells of the body.

Source: www.technologyreview.com The video shows 3000 bacteria maneuvering a V-shaped robot around via computer control. Researchers in Canada have created a solar-powered micro-machine that is no bigger than the period at the end of this sentence. The tiny machine can carry out basic sensing tasks and can indirectly control the movement of a swarm of bacteria in the same Petri dish. Sylvain Martel, Director of the nanorobotics Laboratory at the École Polytechnique de Montréal, previously showed a way to control bacteria attached to microbeads using an MRI machine. His new micro-machine, which measure 300×300 microns and carry tiny solar panels, will be presented this week at ICRA ‘09 in Japan. On such a small device there is little room for batteries, sensors or transmitters. So the solar cell on top delivers power, sending an electric current to both a sensor and a communication circuit. The communication component sends tiny electromagnetic pulses that are detected by an external computer. The sensor meanwhile detects surrounding ph levels–the higher the ph concentration, the faster the electromagnetic pulses emitted by the micro-machine. The external computer uses these signals to direct a swarm of about 3000 magnetically-sensitive bacteria, which push the micro-machine around as it pulses. The bacteria push the micro-machine closer to the higher ph concentrations and change its direction if it pulses too slowly. This is more practical than trying to attach the bacteria onto the micro-machines, says Martel, since the bacteria only have a lifespan of a few hours. “It’s like having a propulsion engine on demand,” he says. Martel suggests that micro-machines could one day be used for medical purposes although there’s still a long way to go.

Single units of a nanometer is one billionth of a meter. Nanotechnology in medicine makes use of nanometer sized chips to store and interprets high density quality information. It shows desired utility in accordance with pre-programmed instructions on target tissues. It is increasingly being applied to coax regulation of functional systems at the molecular level. This micro-miniature technology is increasingly finding its way to cure diseases with out the use of surgery. Most of our ailments are the external manifestations of damage caused at the cellular and molecular levels. Rectification to these damages can not be undertaken by conventional surgical instruments too large and crude for the cellular and molecular level manipulation.
Currently when much research is being carried out in cell biology and genetics at its basic precision and accurate level, the call of the hour is devising of a technology that is able to cater to the structure and functions at this level. The nanotechnology is being engineered to intervene as molecular-machines which are sophisticated and well controlled at the unit level. With the use of this technology the micro-molecules injected in the human body will be able to remove obstructions of any kind, function as sub cellular organelles, and kill cancer cells and much more. Nano engineers in Singapore have engineered a polymerized contact lens which is capable of will releasing small amounts of medicine to treat eye related ailments such as glaucoma.
The mechanism that will function behind nanotechnology at cellular level is by way of designing and erecting a programmable self-replicating manufacturing devise capable of identifying defective cells whilst circulating in the circulating system. These devices which are programmable and controllable can detect cancer cells by sensing differential environment between the normal cells and cancer cells and any other unwanted structures. Nanotechnology will be used to supply oxygen to tissues having minimized blood supply due to any of the blood loss reasons. Scientists at MIT have used an artificially synthesized polymer attached to a specific gene coding for the bacterial toxic. The polymer acts like a suicide bomber and attacks the altered cells and gradually destroys it in the process.
Drug delivery to the specific target cells with the help of nano sized particles is more efficient due to its enhanced properties of solubility and absorption when attached to a molecular carrier such as a polymer. The bio-chips making use of nanotechnology will also facilitate the scrutinizing of levels of biochemical in the blood stream and release suitable drug accordingly.
