Nanotechnology and its Scale

Nanotechnology involves the study and manipulation of entities at the nanoscale, which ranges from 1 to 100 nanometers.
A nanometer is approximately the size of 10 hydrogen atoms or one billionth of a meter.

Properties such as optical, electrical, and chemical characteristics change at the nanoscale.
Electromagnetic forces dominate over gravitational forces at this scale.
Researchers use instruments like electron scanning microscopes and atomic force microscopy to conduct research in the nano field.

Nanotechnology finds applications in health technology, environmental technology, and the production of new materials.
Silver nanoparticles are used in antibacterial materials in hospitals and homes.
The Lotus effect inspires the creation of super hydrophobic surfaces, mimicking the water-repellent properties of the Lotus plant.
Nanotechnology enables the development of special fabrics with water-repellent properties.
In electronics, nanotechnology enhances data storage capacity and improves device performance.
Gold nanoparticles are utilized in medicine for cancer diagnosis and treatment by absorbing radiation and destroying tumors.

Nanoparticles may pose risks to human health and the environment if released during production, transportation, storage, or consumption.
Inhalation, ingestion, or skin contact with nanoparticles can lead to diseases and health issues.
The use of nanotechnology requires careful evaluation of both its benefits and potential risks.

Nanotechnology is a rapidly developing field that has a significant impact on our daily lives.
Informed decisions are necessary regarding the use of nanotechnology, considering both its benefits and risks.
Nanotechnology presents opportunities for researchers, engineers, doctors, and lawyers to contribute to its responsible development and application.
