What is nanotechnology?

Nanotechnology is the study and application of extremely small things and can be used across all other science fields, such as chemistry, biology, physics, material science and engineering. Also the engineering of funcional systems at the molecular state.

Applications of Nanotechnology:

Food

Nanotechnology is used in food production in many ways including ensuring the safety of food products. It is used to test for contamination of diseases including E. coli and bacteria. It is also used to cover up unwanted tastes in food.

Sunscreen
When sunscreen is applied, the two most common ingredients- Zinc Oxide (ZnO) and Titanium Dioxide (TiO2)- give the skin a white tinge. The nanotechnology in sunscreen reduces the visibility by replacing traditional forms of those two ingredients with nanoparticles of these substances. Sunscreens that utilize nanoparticles are extremely effective in absorbing light in the UV range. Due to particle size, they spread more easily, cover better, and save money since you use less. Available science suggests that the nano-tech based sunscreens may be among the safest and most effctive in the market.

Medicine

Investments in nano medicine could lead to breakthroughs in terms of detecting, diagnosing, and treating different forms of cancer. It is also being used for more effective drug delivery systems and is in early stage development as scaffolding in nerve regeneration research. They deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). Also involves longer range research that involves the manufactured nano-robots to make repairs at a cellular level.

Electronics

Nanotechnology helps to increase the capabilities of electronic devices by reducing their weight and power consumption. It also improves display screens and the density of memory chips. Nanotechnology makes it possible to decrease the thickness of the screen.

What do the silver nanoparticle applications have in common?

They are all used to fight viruses and increase antibacterial sufficiency.

Uses of Silver Nanoparticles:


Pacifiers
Pacifiers are susceptible to many bacteria, some manufacturers have begun to coat them in silver nanoparticles. They effectively kill any bacteria, viruses, and fungi that metabolize oxygen and leave the surrounding material unaffected.

It is important for pacifiers to be sterile because it keeps babies from getting sick

Household Products

They are used for fighting bacteria in household products such as toys and laundry detergent.

Clothing

Silver Nanoparticles are used in some clothing to help prevent flu and colds. It helps to give the clothing an ability to deactivate many harmful viruses and bacteria.

Medicine

Silver nanoparticles stop ions from being brought in the virus-producing cell and suffocates it. It aids in stopping viruses.Silver nanoparticles are used in biological implants, such as heart valves, and bandages.

One Drawback of Silver Nanoparticles:

The manufacturing of nanoparticles produces waste that can contaminate the air and animal and plant cells.
