Question 3 of 20

A nanometer measures around one-billionth of a meter.

... Nanometers are so small, around one-billionth of a meter, that even the most powerful microscopes can't see them.

Question 4 of 20

A single nanometer measures about the same width as a human hair.

... One strand of hair measures 100,000 nanometers in width.

Question 5 of 20

Scientists use the term grey goo to describe a nanorobotic takeover.

... The term is grey goo, but relax. Even the scientist who coined this term no longer considers it a possibility.

Question 6 of 20

Nanotechnology was first introduced in 1979.

... The concept of nanotechnology dates back more than 50 years, to 1959.

Question 7 of 20

Nano-magnets remove up to 99 percent of arsenic in polluted water.

... Nano-magnets have shown tremendous success in the field of treating polluted water, and can remove up to 99 percent of arsenic from contaminated water.

Question 8 of 20

Scientists have used nanotechnology to replace cancerous cells in the body.

... Cells are not replaced by nanotechnology. Instead it's used to treat cancerous cells without damaging healthy cells nearby.

Question 9 of 20

Zeolites are a type of rock used to treat contaminated water.

... Zeolites are rocks that filter pollution and keep air and water clean.

Question 10 of 20

The Foresight Society is a leading organization in nanotechnology development and research.

... The Foresight Institute provides information for the public, as well as researchers in this field.

Question 11 of 20

Miners have used nanotechnology to extract oil from the Alberta Oil Sands.

... Miners have used nanotechnology to extract oil from the Alberta Oil Sands and it has helped reduce the amount of pollution and minimize the water consumption during the process.

Question 12 of 20

Nanorobots will likely consist primarily of helium.

... If nanorobots are ever brought to life, they will likely be carbon-based.

Question 13 of 20

Graphene offers an exciting alternative to silicon in the development of nanorobots.

... Graphene makes an ideal alternative to silicon and it measures just one atom thick.

Question 14 of 20

Nano-based solar cells are twice as effective as silicon in capturing solar energy.

... New nano-based solar cells capture as much as 30 percent of solar energy, while silicon based cells capture just 6 percent of solar energy.

Question 15 of 20

Fuel cells rely on a membrane that allows a specified amount of hydrogen to pass through.

... Fuel cells may power cars and portable electronics within the coming years.

Question 16 of 20

X-ray bubbles allow doctors to spot-deliver chemo to cancerous cells.

... Once the medication is in place in the body, doctors use ultrasound waves to send signals to the "bubbles" to tell them when and where to release the medication.

Question 17 of 20

The DxBox is used for pregnancy testing in third-world countries.

... The DxBox is a portable device used to test people in remote or underdeveloped regions for malaria and other diseases.

Question 18 of 20

Three million people worldwide die each year from malaria and TB combined.

... Many of these 3 million deaths are preventable with proper medical care and testing.

Question 19 of 20

The DxBox eliminates the need for refrigeration when testing for malaria.

... Using dried reagents and nano-plumbing systems built into the face of the DxBox, doctors can perform basic blood tests without the need for refrigeration.

Question 20 of 20

Nanotechnology may allow scientists to create an invisibility cloak.

... Nano particles allow scientists to bend light around an object, making it invisible.
