Nanotechnology
What is Nanotechnology?
It is the use of materials at a nanoscale to improve the properties of the products, make them lighter or stronger, etc
How and why is Nanotechnology used in Sunscreen?
Nanoparticles are added to the sunscreen to protect the skin from UV rays.
Why is cost a challenge for Nanotechnology?
Because it's so expensive the average person can't afford it.
What is an atom?
They are defined as “the basic building blocks of matter.” They are very small and join together with other atoms and create matter.
What is a cell?
The smallest unit that can live on its own and makes up all living organisms and the tissues of the body.
How small is a Nano?
A single strand of human hair, for scale, is typically 1 million nanometers thick! That's REALLY SMALL!
What positive things can happen if you use Nanotechnology in Clothing?
Adding Nanomaterials in clothing can make it more water resistant, more durable and reduce odor.
Why is privacy a challenge for Nanotechnology?
Nanotech could get hacked and your information stolen. It could be listening to you or know your location.
What is conductivity?
The ability of a material to conduct electricity or heat.
What is a Nanoscientists?
They study substances on the nanoscale to create new types of materials.
How can you see Nanotechnology?
With a special microscope called a scanning tunneling microscope (STM)
How can Nanotechnology help with energy?
Adding nanomaterials to solar panels makes them more efficient in converting the sun's light into electricity. Nanotechnology can also be used to improve energy storage in batteries.
What are some safety concerns with Nanotechnology and your health?
We don't thoroughly understand the potential health risks associated with exposure to nanomaterials. Nanoparticles can behave differently than larger particles and may have unexpected toxic effects.
What are Textiles?
Any cloth or goods such as a fiber or yarn, used in or suitable for weaving.
What is a Nanometer?
A nanometer is one billionth of a meter.
Why is Nanotechnology so important?
It can do things we have never done before. It can create or better things that are so small we can't even see them! It has so many applications!
Why is Nanotechnology so important in the medical field?
Because it can used targeted diagnosis, treatment and could possibly cure some diseases in the future like cancer and diabetes.
What is a challenge with the environmental impact Nanotechnology could have?
Nanomaterials may pose risks to the environment during their production, use, and disposal phases. We don't know all the things that could harm or pollute the environment at this time.
What is materials synthesis?
A process of creating new materials by combining elements or compounds. Its a key part of chemistry and materials science and engineering.
What is bioimaging?
A non-invasive technique that uses imaging to study biological processes. It can be used to visualize the structure and function of living organisms, cells, and tissues.
What is the difference in the top down approach and the bottom down approach?
Top down involves the breaking down of large pieces of material to generate the required nanostructures from them.
Bottom Down involves assembling single atoms and molecules into larger nanostructures.
How are Nanomaterials used in Electronics?
They improve strength and durability in things like smartphones, laptops and TVs. They can also store more data on smaller chips for these items.
What do you think is the biggest challenge with Nanotechnology now or in the future?
Accept reasonable answers
What is Regenerative Medicine?
A field of medical science that aims to repair or replace damaged tissues and organs, restoring their function. It utilizes various techniques to stimulate the body's natural healing process or introduce new cells, tissues, or organs.
What is a catalysis?
The process of adding a catalyst to facilitate a reaction. During a chemical reaction, the bonds between the atoms in molecules are broken, rearranged, and rebuilt, recombining the atoms into new molecules.
