Highest precision: Microstructured fiber measures the size of nanoparticles

Better research into environmental and bioanalytical issues in the future

08-Dec-2022 - Researchers at Leibniz Institute of Photonic Technology (Leibniz IPHT) developed a new glass fiber design that enables exceptionally long observations of a large number of individual, freely moving nanoparticles in a liquid. This allows the size distribution of nano-objects in a sample to be ...

Exposing what’s in tattoo ink

Ingredient lists often aren’t accurate

29-Aug-2022 - From life-like faces to elaborate nature scenes, tattoos are a true art form. Although people have decorated their bodies for millennia for ceremonial and religious reasons, many people today adorn themselves with these images as a form of self-expression. But the inks used for tattoos are ...

Breakthrough in sizing nanoparticles using fluid-filled tubes

Simple mechanical tube key to measuring mass and size of nano-particles simultaneously

31-Aug-2021 - The functionality of nanoparticles in a host of applications, including drug delivery and nano-optics, is often dictated by their mass and size. Measuring these properties simultaneously for the same nanoparticle has also been challenging. Now scientists from the University of Melbourne and ...

Highly sensitive gas sensors for volatile organic compound detection

03-Feb-2017 - Volatile organic compounds (VOCs) are a group of carbon-based chemicals with low evaporation or vaporization points. Some VOCs are harmful to animal or environmental health so sensing these gasses is important for maintaining health and safety. VOCs also occur in nature and can be useful in ...

High-resolution imaging reveals new understanding of battery cathode particles

02-Feb-2017 - Using advanced imaging techniques, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have been able to observe what exactly happens inside a cathode particle as lithium-ion batteries are charged and discharged. In a research project led by Berkeley Lab ...

When push comes to shove: Size matters for particles in our bloodstream

06-Oct-2016 - Researchers at the University of Connecticut have uncovered new information about how particles behave in our bloodstream, an important advancement that could help pharmaceutical scientists develop more effective cancer drugs. Making sure cancer medications reach the leaky blood vessels ...

NIST nanofluidic 'multi-tool' separates and sizes nanoparticles

11-Aug-2010 - A wrench or a screwdriver of a single size is useful for some jobs, but for a more complicated project, you need a set of tools of different sizes. Following this guiding principle, researchers at the National Institute of Standards and Technology (NIST) have engineered a nanoscale fluidic device ...
