The Bionanoprobe: hard X-ray fluorescence nanoprobe with cryogenic capabilities [PDF]

open access: yesJournal of Synchrotron Radiation, 2013
Hard X-ray fluorescence microscopy is one of the most sensitive techniques for performing trace elemental analysis of biological samples such as whole cells and tissues. Conventional sample preparation methods usually involve dehydration, which removes cellular water and may consequently cause structural collapse, or invasive processes such as ...

X-ray-Induced Shortwave Infrared Biomedical Imaging Using Rare-Earth Nanoprobes [PDF]

open access: yesNano Letters, 2014
Shortwave infrared (SWIR or NIR-II) light provides significant advantages for imaging biological structures due to reduced autofluorescence and photon scattering. Here, we report on the development of rare-earth nanoprobes that exhibit SWIR luminescence following X-ray irradiation. We demonstrate the ability of X-ray-induced SWIR luminescence (X-IR) to
