In recent years with technological advances, science and technology have found ways to deviate into several different aspects such as medicine, electronics, environmental, energy, space, food, chemical sensors, consumer products, molecular manufacturing, micro electromechanical systems, carbon nanotubes, graphene, Bucky-balls, Nano-composites.
In terms of Medicine, researchers have found ways to contribute to cancer cell destruction, disease prevention and resolution, radiation treatments, damage detection, and teeth regeneration. Most applications of nanotechnology in medicine that are being developed involve employing nanoparticles to deliver treatment to specific types of cells. Particles are engineered so that they are attracted to diseased cells. The nanotechnology then allows direct treatment of those cells. This technique reduces damage to healthy cells in the body.
To help aid in cancer destruction, researchers developed two types of nanobubbles. Nano-bubbles, when heated, can destroy cancer cells or can open a temporary hole in a cell wall to allow for drug injection. The researchers are planning this method to selectively destroy certain types of cells, and modify others. Researchers are also using a method being developed to tackle immune diseases by using nanoparticles. Nanoparticles attach to DNA strands and allow white blood cells to quickly tackle the disease. To optimize radiation therapy in the treatment of cancer, nanoparticles are being used to concentrate radiation. Nano particles are being researched for use on other health related problem such as organ damage, more specifically kidney damage, A test for early detection of kidney damage is being developed. Ever had teeth problems? Researchers in nanotechnology are developing ways to regrow the pulp inside teeth, allowing the tissue inside decayed teeth to be regenerated. If these technological gains in nanotechnology are developed, then they will truly make a tremendous impact in maintain a healthy homeostasis.

Nanotechnology in space is a very interesting endeavor. Space can employ carbon nanotubes to reduce spaceship weight while retaining or increasing the structural strength of the spaceship. Using carbon nanotubes could also lead to future developments such as the space elevator, a system which could significantly reduce sending materials into orbit. Nanotechnology could also be used on planets such as Mars to trace for water or other biological material. Other things in space that can be created include lightweight solar sails that use the weight/pressure of sunlight to propel spacecraft. Working with nanosensors can also monitor chemicals onboard in spacecraft to help maintain safety for the astronauts. Nanotechnology can also create bio-nano robot space suits that can administer drugs, fix punctures, and maintain astronaut safety. Nanoparticles can also be produced into thrusters for spacecraft during interplanetary missions. Another field of nanotechnology is food. Researches are using nanoparticles to create barriers to gasses or moisture protection used for packaging. This reduces food spoilages or drying out.
Nanoparticles can also be used to block UV rays and provide anti bacterial protection of packaging, while improving the strength and stability of the plastic film. Nanosensors are being developed that can detect bacteria and other contaminates, such as salmonella, at a packaging plant. This will allow for frequent testing at a much lower cost than sending samples to a lab for analysis. Nanoparticles in food safety can help reduce contaminates. Research is also being conducted to develop nanocapsules containing nutrients that would be released when nanosensors detect a vitamin deficiency in your body.. “Interactive” foods are being developed that would allow you to choose the desired flavor and color. Researchers are also working on pesticides encapsulated in nanoparticles; that only release pesticide within an insect’s stomach, minimizing the contamination of plants themselves.

Chemical Sensors can be used in nanotechnology. Sensors are able to detect very small amounts of chemical vapors. Various types of detecting elements change their electrical characteristics, such as resistance or capacitance, when they absorb a gas molecule. This allows the detection of a very low concentration of chemical vapors. The capability of producing small, inexpensive sensors that can quickly identify a chemical vapor can be useful in a number of ways. An obvious application is to mount these sensors throughout an airport, or any facility with security concerns, to check for vapors given off by explosive devices. These sensors can also be useful in industrial plants that use chemicals in manufacturing to detect the release of chemical vapors. This nanotechnology can also help detecting air pollution. Consumer products integrated with nanotechnology have already hit the shelves. Aerogel, insulation for one’s house, is a perfect example of nano technology. Aerogel only requires a fraction of conventional insulation to retain heat within your household. Solar cells that charge phones and other devices on the go also use Nanotechnology.

Other applications in this area include; creating a paint that can be used an inexpensive solar cells by using it on surface, producing ultracapicators that can store much more energy in hybrid cars than batteries can, generating electricity in waste heat. Researchers have also created artificial muscle tissue composed of carbon nanotubes.
These muscles are significantly stronger than those of natural muscles. Nanotubes bound to an antibody that is produced by chickens have been shown to be useful in lab tests to destroy breast cancer tumors. Researchers at the University of Connecticut have developed a sensor that use nanotubes to detect oral cancer at an accurate and timely manner. Nanotubes can also have therapeutic drugs attached to them and be used when the body needs them. NASA is developing an implant called biocapsule to protect astronauts from the effects of radiation. The implant may also be useful for releasing insulin in diabetic patients and for delivering chemotherapy drugs directly to tumors. Nanotubes can also be used as a scaffold to improve the healing process for broken bones. Nano tubes can also be used to deliver proteins and quantum dots into cancer cells. Carbon Nanotubes can be used in multifaceted ways. Nanotubes can be used to clean up oil spills, run reverse osmosis desalination, sense chemical vapor, detect water contamination, build transistors, act as a flat display panel, use as printer ink, and become flexible electronic devices. Nanotubes can be used as multiple different things. It is truly amazing to see their possibilities and the countless possibilities they can ensue if they are pursued.

Nanocomposites have many medicinal, electrical, and structural pathways that can be pursued. Buckyballs were one of the first nanoparticles ever discovered. Buckyballs are composed of carbon atoms linked to three other carbon atoms by covalent bonds.
However, the carbon atoms are connected in the same pattern of hexagons and pentagons you find on a soccer ball, giving a buckyball the spherical structure Bucky balls may be used to help prevent allergic reaction. The antioxidant properties of buckyballs may be able to fight the deterioration of motor function due to multiple sclerosis.
