Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Design and performance of an X-ray scanning microscope at the Hard X-ray Nanoprobe beamline of NSLS-II [PDF]

Journal of Synchrotron Radiation, 2017
A hard X-ray scanning microscope installed at the Hard X-ray Nanoprobe beamline of the National Synchrotron Light Source II has been designed, constructed and commissioned. The microscope relies on a compact, high stiffness, low heat dissipation approach and utilizes two types of nanofocusing optics. It is capable of imaging with ∼15 nm × 15 nm spatial

Enzyme‐Activated MRI for In Vivo Glucose Imaging via a Biodegradable Chromium Nanoprobe

Advanced Science, EarlyView.
Enzyme‐activated MRI (eaMRI) using a biodegradable CrGOx@Lip nanoprobe enables glucose‐specific imaging in vivo. GOx catalyzes glucose oxidation, triggering in situ formation of paramagnetic chromium gluconate and amplifying T1. This radiation‐free strategy maps tumor glucose uptake via the Warburg‐effect, quantifies hepatic glucose accumulation in ...

Probing the exotic emission behaviors of Gd3+ ions in Gd3Ga5O12 wafer via X-ray excited optical luminescence

Results in Optics
We investigate the exotic emission behaviors of gadolinium gallium garnet (Gd3Ga5O12, GGG) wafer via X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) in an X-ray nanoprobe beamline. The XANES spectra of the Gd L3

Luminescence and X-ray Absorption Properties of Uniform Eu³⁺:(H₃O)Lu₃F₁₀ Nanoprobes

Nanomaterials, 2019
Due to the high atomic number of lutetium and the low phonon energy of the fluoride matrix, Lu-based fluoride nanoparticles doped with active lanthanide ions are potential candidates as bioprobes in both X-ray computed tomography and luminescent imaging.
