Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

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

open access: yesAdvanced 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.

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...
