Nanotechnology is the creation of
Health and Safety Issue
Societal and Philosophical Issues
Nanotechnology can improve many physical, chemical, and biological properties of materials, which can be very useful for many industries, including biomedical, aerospace, textile, cosmetic, manufacturing, oil, agricultural, defense, and electronic.
ISSUES IN NANOETHICS
Philosophical, Environmental, Safety, and other legal issues
materials, components, devices and systems at near atomic or molecular levels.
This emerging technology involves fabricating, imaging, measuring,
modeling, and manipulating matter at
this scale. The goal of nanotechnology is to control individual atoms, molecules, or particles to significantly improve the physical, chemical, and biological properties of materials and devices for various purposes.
A number of nanotechnology products (or nanomaterials) are in the form of metals and alloys, ceramics, polymers, composites, and combinations of these forms, and they vary in size and shape.
- Health and Safety Issue
-Societal and Philosophical Issues
Health issues involving nanotechnology
involve the possible effects of
and on human health.
Extremely high surface area nanomaterials are much more readily absorbed by the body than larger-sized particles, through inhalation, dermal exposure, and ingestion
It is known that several nanomaterials are safe and are used for various applications; therefore, it is important to clearly differentiate those nanomaterials that cause disease or health concerns.
Carbon nanotubes (CNTs )
are highly toxic and can cause asbestos-like effects in the human body.
The use of nanomaterials has been continuously increasing around the globe because rapid developments in this field. Without these materials, the quality of the life would most likely be lower,and life expectancy would probably be shorter.
Major applications include biodevices and biosensors, implants, protection equipment, antibacterial materials , drug delivery, and cosmetics.
Social scientists and organization workers in the field recommend that the social issues be well understood and that all risks and impacts of the technology be well defined for the public. They also suggest that the public participate in every decision made by scientists and government agencies on nanotechnology and its products
Ethical issues pertaining to workplace situations involving nanomaterials.
is a generic name for all the waste generated by nanomaterials and devices during the manufacturing process, which also raises a deepconcern about the limitation of an economic
can also be more dangerous than other conventionally used waste materials because of its size, shape, surface energy, and surface reactivity.
During the manufacturing, transportation, and waste disposal processes, nanomaterials can contaminate the air, water, soil, and food supply
The most human-made nanomaterials do not appear in the environment, so living organisms may not have an appropriate immune system to deal with these nanoscale products
materials have a great potential to benefit the environment and humans
The nanoscale process will be more efficient at removing suspended particles and ions in the water, and faster and inexpensive compared to the traditional precipitation and filtration methods
The educational progress has not been as fast as the technological development. In other words, technical training is not sufficient for individuals working in the field; parallel training is required, which will be useful for the societal and ethical implications of the technology
Providing interdisciplinary and multidisciplinary training of nanoethics for students and scientists, as well as technologists, engineers, medical practitioners, social scientists, workers, and humanists in every discipline will offer great benefits.
In addition to these measures, other actions may include television, media, and online news to inform students and the public. A departmental website should be prepared and should continuously upload and display the most-current information. Government agencies, such as the Food and Drug Administration (FDA), the Environmental Protection Agency (EPA), the
National Institutes of Health (NIH), the Department of Health and Human Services (DHHS), and private companies (IBM, GE, GM, etc.) should have financial support and actively participate in
the educational issues of nanoethics.
Nanomaterials and devices can greatly benefit human life as well as the environment because of
their extraordinary physical, chemical, physicochemical, and biological properties. Some
nanoproducts are completely safe and will degrade without harming the body or environment after their use.
Nanoethics deals with all of these harmful effects of nanotechnology and
nanoproducts in order to create a safer work environment for students, scientists, engineers, and
other individuals participating in nanotechnology research, development, and education.
Nanotechnology Products (or nanomaterials) also can be materials because of the way they are manipulated on an atomic scale.
Nanoscience and nanotechnology are the study and application of extremely small things .
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about
1 to 100
HOW IT STARTED
The ideas and concepts behind nanoscience and
nanotechnology started with a talk entitled
“There’s Plenty of Room at the Bottom”
by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used.
physicochemical, and biological properties of materials
THERE ARE USED IN:
Aircraft and spacecraft
Nanomaterials are used for various reasons:
Developing functional and sensitive sensors, power sources, communication, navigation, and related systems with very low mass, volume, and power consumption.
Revolutionizing aircraft, and spacecraft, and other transportation vehicles.
Developing ultra-small probes on planetary surfaces for agricultural applications and control of soil, air, and water contamination.
Collecting data for analysis, simulation, and modeling.
Recent studies have shown that nanomaterials can be found in air, water, soil, plants, and,
subsequently, human and animal bodies.
Some nanoscale materials can enter the
body using a variety of routes, such as inhalation, ingestion, and/or contact through skin, and
they can persist in the system for longer periods of time. Several kinds of sicknesses can be
expected from exposure to nanomaterials, including asthma, bronchitis, lung and liver cancer,
