The rapid increase in the world’s population has subsequently increased the demand for food supply. Farmers often lose their agricultural produce due to pathogenic infestations, poor soil conditions, water, and environmental factors. Scientists believe nanobiosensors can play a crucial role in revolutionizing the farming system by determining threats to prevent agricultural loss.
Read moreScientists make extensive use of X-ray fluorescence to map elements in materials. However, this technique does not have the needed spatial sensitivity unless the probe is finely focused.
Scientists have now found a way to turn X-ray fluorescence into an ultra-high position-sensitive probe to measure tiny internal structures called nanostructures in thin films (Nature Communications, “Reconstruction of Evolving Nanostructures in Ultrathin Films with X-ray Waveguide Fluorescence Holography”). These thin films can be a hundred times finer than a human hair.
