Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

Advanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers

Portable X-ray fluorescence spectrometer with an electric battery

BUNSEKI KAGAKU, 2004
A potable X-ray fluorescence spectrometer composed of an electric battery X-ray generator and a silicon drift detector was made. Several kinds of samples, including toxic elements, such as lead and cadmium, were measured in air using this spectrometer. A possibility to analyze these toxic elements is discussed.

Portable X-ray fluorescence of zinc applied to human toenail clippings

Journal of Trace Elements in Medicine and Biology, 2020
Zinc is an essential trace element in humans. Zinc deficiency can result in a range of serious medical conditions which include effects on growth and development, the immune system, the central nervous system, and the gastrointestinal system. Diagnosis of zinc deficiency is often precluded by the lack of a noninvasive and reliable biomarker.
