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...

In the article “Pinpointing Cancer Fight,” Liz Szabo states the uses of nanotechnology and how researchers are attempting to use this advancement to fight cancer. She defines that nanotechnology is a type of technology that creates devices on an atomic level; this equipment can allow people such as researchers to use its ability to detect cancerous cells as well as treat them. Szabo remains a neutral tone as she states that while some are against the idea of using nanotechnology since there are many risks, others are optimistic that it may lead to transformational results. She presents a list of some products developed through nanotechnology and explains its usage in addition to mentioning the failure of those nanotech products. Szabo provides

Almost everyone is touched by cancer in some way and the number of people living with and beyond cancer grows greater every year. Globally 14 million people are diagnosed with cancer each year and 8 million people will die from it annually. Half of all men and one-third of all women will develop cancer during their lifetime. (13) There are many treatments for cancer, mainly: surgery, radiation and chemotherapy. These traditional treatments have many negative side effects. Therefore, increasingly, other treatments, such as hormonal therapy and targeted therapy are being used for certain cancers. Nanotechnology is a form of targeted therapy that destroys cancer tumors with minimal damage to healthy tissues and organs. Scientists are already using nanotechnology in early detection of elimination of cancer cells before they form tumors. But the real game changer will be when nanotechnology targets cancer tumors in treatment (11,13).
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.

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
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...
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
Biosensor has intensive specificity. Biomaterial only senses definitive ingredient and it is not affected by colour and concentration of measured material.

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....

Nanotechnology includes nanorobots which are so small that they can be injected into the human bloodstream after which the nanorobots can do investigations or repair at cellular level. Nanorobots could optimize the delivery of pharmaceutical products, these means that medicines which are targeted on a specific type of cells can be delivered to only those cells by the nanorobots. The robots can attach to the cells after which they can inject the drug into the target cells. This could be a great breakthrough for cancer treatments such as chemotherapy because there is a minimal chance of injecting healthy cells with the drug and therefor negative side effects can be avoided.
