A colorized electron microscope image shows lipid nanoparticles containing a cancer drug. The amount of drug contained depends on the size of each nanoparticle. NIST researchers have developed a new analysis to better understand how the useful properties of nanoparticles depend on their size — in this example, to optimize drug delivery to cancer patients. The new analysis can also find use in other products that use nanoparticles and other nanomaterials, including electronics, ceramics and coatings.

Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive error of data analysis that can give misleading insights into how these tiny objects’ properties depend on their size. The team also offers a practical solution — a mathematical correction that can reveal how these materials truly behave.
The Kibble balance is an apparatus that will be used to realise the kilogram after its redefinition in May 2019 based on a fundamental constant – the Planck constant. It compares the gravitational force on […]
PTBnews 3.2018 – PTB is developing a measuring system based on pulse-driven Josephson voltage standards. This system is designed to allow alternating voltages to be measured with great accuracy at frequencies of up to 100 […]
Studio photographers may be familiar with the 1,000-watt quartz halogen lamps known as “FELs.” Scientists use them too—specially calibrated ones, at least—to test the performance of light sensors that monitor Earth’s weather, plant life and […]
