New rapid test: Only a few seconds to the result

"The new measurement method opens up many possible applications where speed and reliability are required"

23-Dec-2022 - A newly developed rapid test needs only a few seconds to reliably detect pathogens such as SARS-CoV-2. It is based on specially designed magnetic nanoparticles. The current rapid tests for diagnosing infectious diseases are speedy, but not really fast. For example, antigen self-tests, PCR tests ...

Particles pull last drops of oil from well water

Nanoscale solution to ‘produced water’ problem

17-Aug-2018 - Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...

New, old science combine to make faster medical test

23-Jan-2017 - A UCF researcher has combined cutting-edge nanoscience with a magnetic phenomenon discovered more than 170 years ago to create a method for speedy medical tests. The discovery, if commercialized, could lead to faster test results for HIV, Lyme disease, syphilis, rotavirus and other infectious ...

Weighing particles at the attogram scale

15-Jan-2014 - MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram — one millionth of a trillionth of a gram. Weighing these tiny particles, including both synthetic nanoparticles and biological components of cells, could help researchers better understand ...

Nanoneedle is small in size, but huge in applications

30-Apr-2009 - Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition to ferrying tiny amounts of cargo, the nanoneedle can also be used as an electrochemical ...
