Nanotechnology may be a revolutionary science in the future
First to be able to understand that it is nanotechnology, it is necessary to know that the nano prefix is a nanometer (〖10〗^(-9)) is a millionth part;A relationship that we can give as an example is that a soccer ball is a nanometer in relation to planet Earth. Nanotechnology is a science in which design, production intervenes in the use of structures of the size that we explain above.
Reference is almost always made to nanotechnology a science of the small, but it is not only very small structures but encompasses volumetric materials and all its properties and characteristics of the Nanoscale.
Nanomaterials are materials that contain particles with one or more dimensions in the nanoscale, that is: from approximately a nanometer to 100 nanometers.
The manufacture or production of the nanomaterials is given through several processes grinding to the material or of synthesis from the nucleation with the process decline of the particles by condensation and/or coagulation;These last processes are the most common for the creation of nanomaterials and can be carried out in a gas, liquid or colloidal phase.
Nanomaterials can be marketed in different ways either powder or volumetric capacities. During the packaging process the exhibitions can take place during the tasks related to the manipulation of the material, such as the heavy, the mixture, the sieve or the packaging of the product.
Nanotechnology covers several applications in other sciences and technologies. It can be said that nanotechnology is of importance and great impact and influence on our society as it covers a wide field due to its great advances and applications in physics, biology, medicine, material and electronics.
The science of materials here is involved nanotechnology because now the nanoparticles give new properties (within these they make them more resistant to scratch, corrosion, etc.) and reinforce the materials. Example today, there are already some nanotechnological products around us, such as more resistant and light tennis rackets thanks to the use of carbon nanotubes, cosmetics with nanoparticles that facilitate their absorption and coatings that thanks to nanoparticles prevent the deposition of dirt.
Nanomaterials and nanotechnology stand out enough in the new advances in modern medicine since thanks to this science you can obtain miniaturized diagnoses that could be used in the early detection of diseases. Gradually with the advancement of technology, new discoveries have been developing that deal with biocompatibility with implants.
Also, materials are being developed in the engineering of tissues and biomimetic materials that gives the possibility of achieving synthesis of substitution organs;Another important study is about the possibility of bringing nanoparticles inside cancer cells for treatment, by means of heat use.
Entering nanotechnology a little more since it is a new industrial revolution influences medicine (nanomedicine).
Nanomedicine and new innovative ways of treating complex conditions normally associated with old age, such as cancer, cardiovascular diseases, AlzheimerEuropean health systems. While still without finding a cure, the number of patients increases in parallel to the aging of the population of the European Union (EU). The potential benefits that nanomedicine can offer are enough as we said before these advances will give great help with the early diagnosis and give better treatments to people.
The revolution that will make this science that is nanotechnology in medicine The future nanotechnology is a multidisciplinary field that includes areas such as biology, chemistry, physics, material science, engineering, etc., And it is of great importance in fields such as computer science, communications, microelectronics, biotechnology and medicine. At present, nanotechnology is a very rapid growing area, with more than 500 existing products already in the market and it is to anticipate that the number of products and therefore its economic and social impact, is much greater in the next 5years. One of the sectors with the most growth prospects and is beginning to be a reality is biotechnology and medicine, both in the development of new diagnostic techniques and image techniques, and in more effective therapeutic treatments, specifically directed to tissues and organsDamaged.
On the other hand, in what consists of the diagnosis, this science tries to develop new analysis systems for disease detection and give a more effective treatment.
The nanomaterials have a large series of risks-these can be affecting the health and safety of living beings, whether it is any new material where there are few not to say few data on these then the irrigation that these can cause can causeTo the person who is manipulating them, so it is good.
The risks caused by health nanomaterials are those that have specific properties that make them of great interest to the industry;However, without knowing the irrigation it causes for health.
The irrigation for security even though in the previous case there is very little information regarding the dangers that nanomaterials can entail but some of which it can be said that the irrigation that can be given would be those of fire and explosion of nanomaterialsthat is related to working and storage conditions.
To evaluate the irrigation, as the Occupational Risk Prevention Law (LPRL) says that a company must plan preventive action from an initial evaluation of the health and safety irrigation of workers.
Risk evaluation is understood as the process aimed at estimating the magnitude of the health and safety risks of workers derived from work. It is a basic tool to improve safety and health conditions in companies and central axis of risk management. The evaluation consists of a systematic examination of all aspects of work in order to determine:
- What can cause damage or injury,
- If the risks can be eliminated and, if not the case,
- What prevention or protection measures have been adopted or should be adopted to control the risks.
First we must identify the dangers;When nanomaterials, supplies or materials that contain them are processed or manipulated, workers are exposed to a great diversity of risks due to substances and may cause severe damage.
It can also happen that entrepreneurs do not have information about the presence of nanomaterials in the workplace and as a first action they must verify in inventories if there are substances identified as nanomaterials or that may contain them. It is therefore necessary to determine, case by case and collecting all the necessary information, if there is a presence of nanomaterials and the dangers presented by these manometric materials for workers. The information recommended to obtain is as follows:
- Nano form classification,
- Size distribution in particles number,
- Specific surface,
- morphological information (form and size, especially in the case of fibers and in relation to the applicability of WHO criteria),
- surface modification of nanomaterials,
- BioPersistence, Water Solubility or Biological Media,
- Data on product dust emission and flammability data.
But already making known everything about nanotechnology and nanomaterials, it is said that its importance is part that this science allows us to create new devices and systems, new materials through the control of the subject on the nanometer scale and the use ofnew physical, chemical and biological phenomena and properties at that scale of lengths. It is also very common to say that nanoscience is a "horizontal" science because it can be considered to influence practically all sectors. Frequently, it brings together different scientific areas and is favored by interdisciplinary or convergent approaches. It is expected that it allows to introduce innovations that respond to many of the problems facing society today.
And finally nanomaterials are used in almost all industrial sectors and product categories, both in the field of cosmetics and industrial chemical preparations or medicines.
Due to their generalized use, consumers, workers and the environment can also be exposed to them in many different ways.
Workers manipulate them in the form of raw materials in manufacturing processes. When they are processed during the useful life cycle in various industrial applications, many more people will use them, either in products such as paintings or in articles, such as printers. There is a difference between the products and articles that have been manufactured using nanotechnology and those that still contain free nanoparticles when used.
There is a common idea that nanomaterials are considered equal chemical substances than the rest. This idea is equally valid for your situation in a normative context.
The definition of substance is so wide that it also contemplates all forms of substances, including particles to Nanoscale 1-100 Nm (that is, nanomaterials)). However, compared to other substances, nanomaterials can behave differently not only when used in products or items, but also from a point of view of risk assessment.
Therefore, we may have to distinguish nanomaterials from other larger particles in the context of risk assessment and management of the same.
