Harnessing photonics for at-home disease detection

ScienceDaily.com: Nanotechnology News - 2 апреля, 2019 - 18:30
With nothing more than a photonic chip and an ordinary camera, researchers have managed to count biomolecules one by one in a small sample and determine their position. Their tiny device -- a marriage of optics and smart image analysis -- is even able to detect a graphene sheet only a single atom thick. This type of sensor could one day play a key role in personalized medicine.

Harnessing photonics for at-home disease detection

Nanowerk.com - 2 апреля, 2019 - 16:39
In the not-too-distant future, each of us may have a simple device - small enough for our nightstand or our pocket - that keeps us apprised of our level of health, identifies even trace amounts of undesirable biomarkers in our blood or saliva and serves as an early-warning system for diseases. This is one of the promises of personalized medicine.

Cleaning up oil using magnets

ScienceDaily.com: Nanotechnology News - 1 апреля, 2019 - 17:53
In the future, it could be possible to remove oil spills on the surface of the ocean by using magnets. An interdisciplinary group of researchers has developed functionalized iron oxide particles that can attract any types of hydrocarbons. The magnetic particles and their shells can then be removed from the water relatively simply and in an environmentally friendly manner and can even be reused after being cleaned.

Quantum optical cooling of nanoparticles

ScienceDaily.com: Nanotechnology News - 29 марта, 2019 - 20:02
One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature. Researchers are now one step closer to reaching this goal by demonstrating a new method for cooling levitated nanoparticles.

Just add heat to open this tiny box

ScienceDaily.com: Nanotechnology News - 29 марта, 2019 - 16:38
Researchers have designed two types of nano-sized building blocks that can automatically connect into cubes and scramble back into individual components based on the temperature of their environment. This accomplishment is another step towards chemical systems that more realistically mimic life. 'Imagine mixing two liquids together, like ink and water. They will automatically do the simple chemical process of dispersing until they are perfectly mixed,' said Professor Shuichi Hiraoka of the University of Tokyo.
