What are nanofluidics used for?
Microfluidic and nanofluidic device are often used to manipulate the motion of a liquid droplet in biomedical analysis or biochemical operations [1–8].
What are nanofluidic device?
Nanofluidic devices have been built for application in chemistry, molecular biology and medicine. The main purposes to use nanofluidic devices are separation and measurement of solutions containing nanoparticles for drug delivery, gene therapy and nanoparticle toxicology on a micro-total-analysis system.
What is the technique used for measure the size in nanoscale?
Scanning tunneling microscopy (STM) exploits the quantum mechanical phenomenon of quantum tunneling. In this technique, electrons are made to tunnel through a vacuum between the subject’s surface and a conducting tip on the microscope. As the tip scans the surface, the current is monitored and used to produce an image.
What is a nanochannel chip?
Nanochannel is the key structure of nanofluidic chip, and is the important component to determine the performance of nanofluidic device. It is the basis of nanofluidic chip manufacturing, detection and application.
What tool is used to measure nanometers?
The Nano-Gauge™ is an ultra high precision, single axis, displacement measuring instrument capable of resolving dimensions down to 1.5 nanometers (0.06 microinches) over a full scale range of 25mm (1 inch).
Why do scientists use nanometers?
On the nanometer-scale, materials may exhibit unusual properties. When you change the size of a particle, it can change color, for example. “Rather, working at the nanoscale enables scientists to utilize the unique physical, chemical, mechanical, and optical properties of materials that naturally occur at that scale.”
How many nanometers is a strand of hair?
A sheet of paper is about 100,000 nanometers thick. A strand of human DNA is 2.5 nanometers in diameter. There are 25,400,000 nanometers in one inch. A human hair is approximately 80,000- 100,000 nanometers wide.
