Discussion
The emergence of nanotechnology in the health sciences has led to a new discipline known as nanomedicine, whose main objective is to develop tools to diagnose, prevent and treat diseases when they are still less advanced states or the beginning of its development. Nanomedicine studying interactions at the nanoscale and for that use devices, systems and technologies that include nanostructures capable of interacting at the molecular level and micro level are connected to interact at the cellular level (Zhang S. 2002). One of the greatest challenges in this process lies in the development of "Nano-therapies" specifically targ...

The small size ranging from 0.1 to 10 micrometres of nanobots make it difficult to be constructed. The process of working atom by atom and molecule by molecule is monotonous work and the miniaturization of synthetic mechanisms to a nanoscale will only be achievable with the advancement of research in metallurgy.

The field of medical robotics is a relatively new area. The first known documented utilization of robotics in the medical field occurred in the year 1985. A robot aided in placing a needle in the correct position for a biopsy of a patient's brain. Although there is still much to explore and discover in the area of medical robotics, the advances steadily increase at a fast pace. Historically, robots have often been first introduced to automate or ameliorate discrete processes, such as painting a car or placing test probes on electronic circuits, but their greatest economic influence has often come indirectly as essential enablers of computer-integration of entire production or accommodation processes.
Drug peak has disappeared in XRD of Nanoparticle 3 which probably may be due to conversion of Tamoxifen citrate from crystalline state to amorphous state or dissolution during the heating involved in the preparation of solid lipid nanoparticle or may be another phenomenon is drug may be present in polymeric amorphous phase.

Hydrogel micropatches containing E. coli cells is fabricated in microfluidic devices by in situ UV photopolymerization. The main purpose for using E. coli for this study, because it could be easily engineered to express enzymes with desirable properties using recombinant DNA technology. Such enzymes are used for sensing and drug discovery. In order to avoid the flow hindrance in the channel, the hydrogel micropatches are fabricated in such a manner to occupy lesser volume than the microchannel. The viability of hydrogel-entrapped E. coli was performed with the use of dyes that selectively bind to nucleic acids. Lysis proves the ability of small molecules to penetrate the hydrogel and undergo a chemical transformation on the gel-entrapped bacteria. The potency of enzymes within entrapped E. coli is tested by allowing
Gold has long been used within the human body for many surgical treatments. Due to the chemical nature of gold, it does not readily react with other compounds inside the human body and is not damaging to the surrounding cells. Furthermore, it will not corrode or break down because it does not interact with oxygen. This allows scientists to implant gold nanoparticles within cancerous cells in preparation for treatment. After injecting the nanoparticles, which are smaller than a red blood cell, they begin to accumulate within the rapidly-growing cancer cell, where they wait until further treatment.
The Enabling Nanomedicine translation Project (ENATRAS) is a support network whose purpose is to provide and assist with the distribution of nanomedicine programs, research and products throughout
Nano-robotic technology has not caught up to the imagination of fiction writers. There are no autonomous nanobots, no miracle cures for cancer involving robot swimming in your blood vessels. Instead there are parts of future nano-robots which have been created: several viable propulsion options, nano-diagnostic arrays, and a cheap readily available base material. The unique properties of nano-scale materials allow for novel uses in nanobots and could lead to a viable nanobot. The need to create smaller robots for more specialized procedures and therapies has led to innovation in the nano-scale. While no such nanobot currently, one may exist in the near future.
Nano-technology is a revolution in almost all disciplines of life today. Nanotechnology approaches the manipulation of matter at atomic and molecular level. This technology, which deals with matter in nano-dimensions, has widened our views of poorly understood health issues and provided novel means of diagnosis and treatment. Dentistry, not being an exception, also faces major revolutions to constantly provide better and more comfortable dental care to patients. Researchers in the field of dentistry have explored the potential of nano-particles in existing therapeutic modalities with moderate success. The important application in the field of dentistry

Advances in semiconductor technologies since 1970s have paved the way for fabrication of the devices with micron dimensions. These devices were categorized under the MEMS field, which was a combination of mechanical structures with electronic readout circuits. MEMS technology has borrowed its fabrication capabilities from the growing semiconductor field and applied it to different science fields. With application of the MEMS technology in biological sciences a new field has born under the title of BioMEMS field. This field has borrowed the most advanced microfabrication techniques from its parent field, MEMS, and has applied it to the micron size world of the biological particles such as cells, viruses, and bacteria. With recent advances in the microfluidics, BioMEMS has enabled fast prototyping of the medical devices, with higher accuracy and sensitivity with lower fabrication costs and energy consumes. In addition, it has enabled new methods in manipulation of biological particles by production micron sized channels, which can be replicate of human capillary environment. With growing interest in application of the MEMS technology in biology, the study of biophysical properties of the cells has gained further importance. Cells are the most basic and functional part of the complex living systems and study of biophysical (electrical and mechanical) properties of the cells provides an inspection to physical and chemical status of biological organisms. In the past two decades, a number of new approaches are used in studying the relatio...
First of all, scientist built nano bots that can enter the human body and move more efficiently. It's smaller than a strand of hair, about one out of a ten thousandth. They are trying to make intelligent nano bots that work as a swarm to destroy polluted air and water. Phil Kuekes, a computer scientist at Hewlett-Packard Labs and an expert in molecular-scale processors, says that, "Intelligent nano-scale devices could be injected as biological sensors in the body, or for diagnostic purposes in the clinic" (Winner). Smaller devices can be injected into you so doctors can examine the inside of your body better. Just imagine how fast it would be to just inject nano bots into you and after a couple of minutes they could find infections. Small machines are better for research and elimination of pollution so we don't make it any worse by making large machines that produce more toxin. We could create so much with nanotechnology: like make medical bots the repair fractured or broken bones once injected into the human body, or create nano bots that form a protective layer when something is about to impact the body. It could even enhance people to be stronger and jump higher. The nano bots would support the bones and muscles in our bodies to make them stronger....
Nanoparticles are defined as the microscopic particles with at least one dimension less than 100 nm. Nanoparticles are of immense scientific interest because of their vast potential applications in biomedicines, computer, electronics, and defense industries. Nanoparticles are of great scientific and technological interests because they can effectively act as bridge between the bulk form and atomic or molecular structures of the materials. Bulk materials possess constant physical and chemical properties regardless their sizes while nano-scaled materials possess varying properties depending on their sizes [Marignier, J.L., Belloni, J., Delcourt, M.O., Chevalier, J.P.
