The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV, according to a study led by UCL researchers ...
Today, optofluidics is one of the most representative applications of photonics for biological/chemical analysis. The ability of plasmonic structures (e.g., colloidal gold and silver nanoparticles, NPs) under illumination ...
Materials scientists at Duke University have devised a simplified method for calculating the attractive forces that cause nanoparticles to self-assemble into larger structures.
Successful drug development has a significant impact on people's quality of life worldwide. Being able to track how molecules get into target cells, and observing what they do when they are inside, is key to identifying the ...
Special anti-counterfeiting and chemical sensing tools that we can use with our eyes could be created thanks to a new nanoscale building method.
Current state-of-the-art techniques have clear limitations when it comes to imaging the smallest nanoparticles, making it difficult for researchers to study viruses and other structures at the molecular level.
In the quest to image exceedingly small structures and phenomena with higher precision, scientists have been pushing the limits of optical microscope resolution, but these advances often come with increased complication and ...
Every biological system is naturally equipped with a defense mechanism to protect against abnormal changes caused by either local, environmental, or biochemical alteration. White blood cells (WBC) play the role of such a ...
In the search for clean energy alternatives to fossil fuels, one promising solution relies on photoelectrochemical (PEC) cells—water-splitting, artificial-photosynthesis devices that turn sunlight and water into solar fuels ...
Imperial researchers have tested whether gold nanoparticles could be toxic to cells, finding how they affect lipid membranes depends on their size.
