One, slightly controversial, example of biotech In agriculture Is the genetic engineering of crops. Genetically modified (GM) crops are able to produce pesticides that resist insect attacks; environmentally damaging chemicals can therefore be foregone in favor of a less aggressive solution (this last point is, however, subject to much heated debate). Another example of biotech application in agriculture Is the designing of transgenic plants that are able to grow in the absence or presence of certain specific chemicals.
The next time you step out onto a pristine lawn fully kitted out in the appropriate ports equipment, imagine that grass you are standing on has been engineered, at a genetic level, to suit the purposes of your sport! Red Biotechnology: refers to the medical applications of biotech. This Is a very exciting field that Includes the engineering of organisms to produce antibiotics, the use of genetic code manipulation to produce cells used for gene therapy and even, possibly, the prevention of inherited diseases through gene identification, isolation, and destruction.

There are many ethical debates with regards to genetic modification, especially when It comes to human genes. Whatever the Implications of the ethical arguments entail, the very fact that such intervention is a possibility is somewhat staggering. Bioinformatics is an interdisciplinary field which endeavors to find solutions to biological problems using refined and much studied computational techniques. The result of this Is that large amounts of biological data can be organized very quickly for analysis (which is also aided by computing).
Whereas as there are many applications for bioinformatics in research and commercial environments, the field of genetics has benefited greatly from our ability to record, call and Interpret vast quantities of data. Concerns: 1 . Harm to the environment – this concern is perhaps the most widely cited by those opposed to Smog. It is very difficult to predict what will happen in an ecosystem where a new organism has been introduced, whether genetically modified or not. 2. Baptisteries – Governments are worried that terrorists will use biotechnology to create new Superb, infectious viruses, or toxins, for which we have no cures. . Laboratory/Production safety – It’s hard to protect oneself if you don’t know what you’re working with. Some new technologies, usually non-biological, such as inappropriate, make commercial production lines before they have been sufficiently tested for safety. There Is also concern for technician safety In laboratories, even under secured conditions, when working with organisms of 1 OFF cloning genes is sacrilegious, innumerable ethical questions arise over the appropriateness flensing genetic inventions and other IP issues.
In addition, the construction of genes from scratch (the first artificial gene was actually synthesized in 1970) means we might someday be able to create life from a chemical soup which ill most certainly go against the ethical or religious beliefs of a significant number of people.

Tm Nanotechnology is the engineering of functional systems at the molecular scale.
It is the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. This covers both current work and concepts that are more advanced. In its original sense, ‘nanotechnology’ refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. Nanotechnology Applications in: Medicine Researchers are developing customized inappropriate the size of molecules that can deliver drugs directly to diseased cells in your body.
When it’s perfected, this method should greatly reduce the damage treatment such as chemotherapy does to a patient’s healthy cells. Check out ornithological Applications in Medicine page o see how nanotechnology is being used in medicine. Electronics Nanotechnology holds some answers for how we might increase the capabilities of electronics devices while we reduce their weight and power consumption. Check out our Nanotechnology Applications in Electronics page to see how nanotechnology is being used in electronics. Food Nanotechnology is having an impact on several aspects of food science, from how food is grown to how it is packaged.
Companies are developing endometrial that will make a difference not only in the taste of food, but also in food safety, and the lath benefits that food delivers. Check out our Nanotechnology Applications in Footage for the details. Fuel Cells Nanotechnology is being used to reduce the cost of catalysts used in fuel cells to produce hydrogen ions from fuel such as methanol and to improve the efficiency of membranes used in fuel cells to separate hydrogen ions from other gases such as oxygen. Check out our Nanotechnology Applications in Fuel Cells page for the details.
Solar Cells Companies have developed annotate solar cells that can be manufactured at significantly lower cost than conventional solar cells. Check out our Nanotechnology Applications in Solar Cells page for the details. Batteries Companies are currently developing batteries using endometrial. One such battery will be a good as new after sitting on the shelf for decades. Another battery can be recharged significantly faster than conventional batteries. Check our Nanotechnology may hold the key to making space-flight more practical.
Advancements in endometrial make lightweight spacecraft and a cable for the space elevator possible. By significantly reducing the amount of rocket fuel required, these advances could lower the cost of reaching orbit and traveling in space. Check ornithological Applications in Space page for details. Fuels Nanotechnology can address the shortage of fossil fuels such as diesel and gasoline by making the production of fuels from low grade raw materials economical, increasing the mileage of engines, and making the production of fuels from normal raw materials more efficient.
Check our Nanotechnology Applications in Fuels page for details. Better Air Quality Nanotechnology can improve the performance of catalysts used to transform vapors escaping from cars or industrial plants into harmless gases. That’s because catalysts add from inappropriate have a greater surface area to interact with the reacting chemicals than catalysts made from larger particles. The larger surface area allows more chemicals to interact with the catalyst simultaneously, which makes the catalyst more effective. Check our Nanotechnology and Air Quality page for details.
Cleaner Water Nanotechnology is being used to develop solutions to three very different problems in water quality. One challenge is the removal of industrial wastes, such as a cleaning solvent called ETC, from groundwater. Inappropriate can be used to convert the intimidating chemical through a chemical reaction to make it harmless. Studies have shown that this method can be used successfully to reach contaminates dispersed in underground ponds and at much lower cost than methods which require pumping the water out of the ground for treatment.
Check out our Nanotechnology and Water Quality page for details. Chemical Sensors Nanotechnology can enable sensors to detect very small amounts of chemical vapors. Various types of detecting elements, such as carbon annotates, zinc oxide narrowness or palladium inappropriate can be used in nanotechnology-based sensors. Because of the small size of annotates, narrowness, or inappropriate, a few gas molecules are sufficient to change the electrical properties of the sensing elements. This allows the detection of a very low concentration of chemical vapors.

Fabric Making composite fabric with Anna-sized particles or fibers allows improvement of fabric properties without a significant increase in weight, thickness, or stiffness as might have been the case with previously-used techniques. For details see ornithological in Fabrics page. The following are some of the most common concerns expressed by people on the use of nanotechnology: Nanotechnology is a new scientific application. Although this can also mean to be a benefit for mankind, there are safety concerns related to its applications mainly because of the fact that it is something that is not yet fully tested.
One of the safety concerns with nanotechnology in this field involves the application of the technology in medical and health fields. Some are afraid that they might trigger harmful effects instead of the intended beneficial effects. 0 Because nanotechnology involves the manipulation of matter at the atomic and molecular levels, there are fears that such manipulation may result to the production f materials that will radically alter man’s way of life.
This is seen especially to be dangerous in the field of medical applications where Anna particles are used in various ways such as sunscreen and enunciable medications. Safety concerns with nanotechnology in these areas are heightened because such manipulation of matter may trigger the body to react in a negative way to the presence of nanotechnology products. 0 There are also fears that the environment may be placed in Jeopardy that nanotechnology products may increase the pollution level in many areas at a mime when the need for environmental conservation is vigorously pursued everywhere.
For example, the production of better engines for automotive and windows for cars may prompt car manufacturers and local dealers to wantonly discard these parts that can possibly cause environmental nightmare with the absence of better programs on waste disposal. An interesting twist here is nanotechnology is a thriving business in the United States, amounting to billions of dollars. However, despite all these income, very little thought is spared for health and environmental concerns.
Because Anna particles are very small, they are very difficult to degrade and may easily pass on from one person to another, in the process becoming agents of ailments. 0 Another of the numerous safety concerns with nanotechnology is the lack of a centralized monitoring agency that will see to it that all endeavors in this field are religiously monitored. As a proof of this, there are very little Journals and researches on the safety concerns with nanotechnology that inevitably enhances the fears that people may have on this technological applications and advancements.
