Nano-robots are the robots that are simply known as that controllable machine at the nano 10 -9 meter or molecular scale, composed of nano-components.
More specifically, nano robotics refers to the still largely hypothetical nanotechnology engineering discipline of designing and building nano robots. Even though the field of nano robotics is bio nano robotics different from that of the macro robots due to the differences in scale and material, there are many similarities in design and control techniques that eventually could be projected and applied.
Due to the modern scientific capabilities, it has become possible to attempt the creation of nano robotic devices bio nano robotics interface them with the macro world for control. There are countless such machines which exist in nature and there is an opportunity to build more of them by mimicking nature. Nowadays these nano robots play a vital role in the field of Bio Medicine. Especially in the treatment of cancer, Cerebral Bio nano robotics, kidney stones removal, also to remove the defected part in our DNA structure and some other treatments that has the greatest aid bio nano robotics save human lives.
This paper guides to the recent research on nano robots in the Bio medical applications. Nano robots; Cerebral aneurysm; Nanotechnology: Nanotechnology can best be defined as a description of activities at the level of atoms and molecules that have applications in the real world. The bio nano robotics challenge is the ability to measure, manipulate and assemble matter with features on the scale of nm. In order to achieve cost-effectiveness in nanotechnology it will be necessary to automate molecular manufacturing.
The engineering of molecular products needs to be carried out by robotic devices, which have been termed nano robots [ 1 ]. This review chapter focuses on the bio nano robotics of the art in the emerging field of nano robotics, its applications and discusses in brief some of the essential properties and dynamical laws which makes this field more challenging and unique than its macro scale counterpart. Some proponents of nano robotics, in reaction to the grey goo scare scenarios, hold the view that nano robots capable of replication outside of a restricted factory environment do not form a necessary part of a purported productive nanotechnology and that the process of self-replication, if it were ever to be developed, could bio nano robotics made inherently safe.
They further bio nano robotics that their current plans for developing and using molecular manufacturing do not in fact include free-foraging replicator. Nano robots with complete artificial components have not bio nano robotics realized yet. Mother Nature has her own set of molecular machines that have been working for centuries and have been optimized for performance and design over the ages.
The main goal in the field of molecular machines is to use various biological elements whose function at the cellular level creates motion, force or a signal as bio nano robotics components.
These components perform their preprogrammed biological function in response to the specific physiochemical bio nano robotics but in an artificial setting. In this way proteins and DNA could act as motors, mechanical joints, transmission elements, or sensors.
If all these different components were assembled together in the proper proportion and orientation they would form nano devices with multiple degrees of freedom, able to apply forces and manipulate objects in the nano scale world.

It is an advanced nano mechatronics simulator that provides physical and numerical information for nano robot task-based modeling.
The nano robot design is bio nano robotics of integrated nano electronics and components such as molecular sorting rotors and a robot arm telescoping manipulator derived from biological models. The nano robot exterior shape consists of a diamondoid material to which may be attached an artificial glycocalyx surface that minimizes fibrinogen and other blood proteins adsorption and bioactivity, ensuring sufficient biocompatibility to avoid immune system attack.
Different molecules types are distinguished by a series of chemotactic sensors whose bio nano robotics sites have a different affinity for each kind of molecule. These sensors also detect obstacles which might require a new trajectory planning. Sensor design and capabilities depend on the details of the environment and task. Thus, the nano robot requires transducers capabilities and smart sensors directly related to that specific biomedical application. In present study, the nano robot is able to detect obstacles over a range of about 1 mm and within an angular bio nano robotics equivalent to a diameter of nm at that range.
The biomolecules are too small to be detected reliably: This description of interaction capabilities allows evaluating different nano robot sensor based action [ 3 ]. It also helps to choose the kind of low-level control to bio nano robotics the information acquired for an effective real time performance.
The nano robot kinematics can be predicted using state equations, positional constraints, inverse kinematics and dynamics, while some individual directional component performance can be simulated using control system models of transient and steadystate response.
Nano robots are expected to enable new treatments for patients suffering from bio nano robotics diseases and will result in a remarkable advance in the history of medicine.
Recent developments in the field of bimolecular computing, this is a promising first step to enable future nano processors with increased complexity. Studies targeted at building biosensors and nano-kinetic devices required to enable medical nano robotics operation and locomotion, have also been progressing [ 4 ]. The use of nano robots may advance biomedical intervention with minimally invasive surgeries and help patients who need constant body functions monitoring, or ever improve treatments efficiency through early diagnosis of possible serious diseases [ 5 ].
For example, the nano robots may be utilized to attach on transmigrating inflammatory bio nano robotics or white blood cells, thus reaching inflamed tissues faster to assist in their healing process. Nano robots will be applied in chemotherapy to combat cancer through precise chemical dosage administration and a similar approach could be taken to bio nano robotics nano robots to deliver anti-HIV drugs.
Nano robots could be used to process specific chemical reactions in the human body as ancillary devices for injured organs. Monitoring diabetes and controlling glucose levels for patients will be a possible application of nano robots [ 6 ].
Nano robots might be used to seek and break kidney stones. Another important possible feature of medical nano robots will be the capability to locate atherosclerotic lesions in stenosed blood vessels, particularly in the coronary circulation and treat them either mechanically, chemically or pharmacologically. In this case the idea is the development of ribonucleic acid and adenosine triphosphate devices and even the use of modified microorganisms bio nano robotics achieve some kind of bio molecular computation, sensing and actuation for nano robots.
Another approach for the development bio nano robotics molecular machines is the inorganic nano robot. Inorganic nano robots development bio nano robotics based on tailored nano electronics. In comparison with bionanorobots, inorganic nanorobots could achieve a considerably higher complexity of integrated nano scale components.
There are some works on how to enable manufacturing of inorganic nano robots. The use of new diamondoid rigid materials is a possible approach that may help towards achieving new materials for inorganic nano robots.

It may have a bio nano robotics impact on the implementation of the new approaches for manufacturing techniques. Simulation can anticipate performance of new nano devices. Further, it can also help on nano mechatronics design and in testing control and automation strategies. Cancer can be successfully treated with current stages of medical technologies and therapy tools. However, a decisive factor to determine the chances for a patient with cancer to survive is: Another important aspect to achieve a successful treatment for patients is the development of efficient targeted drug delivery to decrease the side effects from chemotherapy.
Considering the properties of nano robots to navigate as blood borne devices, they can help on such extremely important aspects of cancer therapy. Integrated nano sensors can be utilized for such a task in order to find intensity of E-cadherin signals. Therefore a hardware architecture based on nano bioelectronics is described for the application of nanorobots for cancer therapy. Analyses and conclusions for the proposed model are obtained through real time 3D simulation.
Medical nano robots can readily treat genetic diseases by comparing the molecular structures of both DNA and proteins found bio nano robotics the cell to known or desired reference structures. Any irregularities can then be corrected, or desired modifications can be edited in place. In some cases, chromosomal replacement therapy is more efficient than in CY to repair. Floating inside the nucleus of a human cell, an assemblerbuilt repair vessel performs some genetic maintenance.
Stretching a super coil of DNA between its lower pair of robot arms, the nano machine gently pulls the unwound strand through an opening in its prow for analysis. Upper arms, meanwhile, detach regulatory proteins from the chain and place them in an intake port [ 1314 ]. Bio nano robotics molecular structures of both DNA and proteins are compared to information stored in the database of a larger nano computer positioned outside the nucleus and connected to the cell-repair ship by a communications link.
Irregularities found in either structure are corrected and the proteins reattached to the DNA chain, which re-coils into its original form with a diameter of only 50 nanometersthe repair vessel would be smaller than most bacteria and viruses, yet capable of therapies and bio nano robotics well beyond the reach of present-day physicians. Disease would be attacked at the molecular level and such maladies as cancer, viral infections and arteriosclerosis could be wiped out.
The nano robot for brain aneurysm prognosis, using computational nanotechnology for medical device prototyping. Bio nano robotics is consist of three main bio nano robotics are Equipment prototyping, the manufacturing approach bio nano robotics inside-body transduction.
Equipment prototyping is the computational nanotechnology provides a key tool for the fast and effective development of nano robots, helping in the investigation to address major aspects on medical instrumentation and device prototyping. A similar approach was previously taken by industry to build racing cars, airplanes, submarines, ICs and medical devices [ 15 ].
Now, the same can be used to benefit the development and research of medical nano robots [ 16 - 18 ]. The Manufacturing technology for manufacturing purposes of the nano robot should be integrated as a biochip device. Thus, new materials, photonics and nano bioelectronics are presented with a description bio nano robotics the nano robot architecture. And the Inside-body transductions are cell morphology, microbiology and proteomics are used as parameters for nano robot morphology and inside-body interaction.
Changes on chemical gradients and telemetric instrumentation are used for medical prognosis, with the nano robots activation based on proteomic over expression [ 19 ]. As presented in the paper, these three points comprise the key pieces required to advance the development and implementation of medical nano robotics. For brain aneurysm prognosis, nano robots need to track the vessel endothelial injury before a subarachnoid hemorrhage occurs. These changes on chemical concentration are used to guide the nano robots to identify brain aneurysm in the early stages of development Figure 2.
The bio molecules are too small to be detected reliably: The main morphologic aspects related to brain aneurysm are taken for modeling the study of nano robots sensing and interaction within the deformed blood vessel [ 2122 ]. Intracranial concentrations of NOS are small and some false positives can even occur due bio nano robotics some positive functions of N-oxide with semi carbazone pNOS. Cells and nano robots continually enter one end of the workspace along with the fluid flow.
The nano robots must detect protein over expression and the setup for sensing and control activation can be modified for different values, such as adjusting the detection thresholds. We treat any nano robots not responding while within the workspace as if they did not detect any signal, so they flow with the fluid as it leaves the workspace.
In bio nano robotics a case the nano robot ignores the NOS concentration assuming that it is bio nano robotics the expected levels of intracranial NOS. As a practical threshold bio nano robotics medical prognosis, to avoid noise distortions and achieve a higher resolution, each time the cell phone has received at least a total of nano robots higher proteomic signal bio nano robotics, the model considers this as strong evidence of intracranial aneurysm.
