Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting

Advanced Healthcare Materials, EarlyView.
Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

Semiconducting Polymer Nanoparticles as Multimodal Agents for Optical and Magnetic Resonance Imaging

Advanced Healthcare Materials, EarlyView.
Semiconducting polymer nanoparticles (SPNs) exhibit many advantageous optical and biological properties. Multimodal SPN‐based contrast agents that integrate several imaging modalities yield a wealth of information through the use of different imaging mechanisms.

Toward Noninvasively Imaging pH at the Surface of Implanted Orthopedic Devices in Live Rabbits Using X‐ray Excited Luminescence Chemical Imaging

Advanced Healthcare Materials, EarlyView.
Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

Magnetic Resonance Imaging‐Based Quantification of Endosomal Escape Using Iron Oxide Nanoparticle‐Loaded Lipid Nanoparticles

Advanced Healthcare Materials, EarlyView.
The therapeutic efficacy of lipid nanoparticle(LNP)‐based drugs depends on endosomal escape. However, few methods are available for quantifying the efficiency of endosomal escape in vivo. Herein, a novel method for quantifying the endosomal escape efficiency index using magnetic resonance imaging is introduced.

Single-Photon Emission Computed Tomography

, 2007
Single-photon emission computed tomography (SPECT) is an instrument for the evaluation of regional cerebral perfusion and receptor density studies. For the performance of SPECT, a flow tracer or a receptor-binding substance is tagged with a radionuclide and injected intravenously. The flow tracer is assumed to accumulate in different areas of the brain
