Optimized automated radiosynthesis of F-JNJ64413739 for purinergic ion channel receptor 7 (P2X7R) imaging in osteoporotic model rats.

Objective: To optimize the automated radiosynthesis of the purinergic ion channel receptor 7 (P2X7R) imaging agent F-JNJ64413739 and evaluate its potential for brain imaging in osteoporotic model rats.

Methods: A more electron-deficient nitropyridine was employed as the labeling precursor to facilitate the F-labeling. The radiosynthesis was conducted on an AllinOne synthesis module, and followed by purification via high-performance liquid chromatography (HPLC).

Fully Elastomeric Fingerprint-Shaped Electronic Skin Based on Tunable Patterned Graphene/Silver Nanocomposites.

Multifunctional electronic skins (e-skins), which mimic the somatosensory system of human skin, have been widely employed in wearable devices for intelligent robotics, prosthetics, and human health monitoring. Relatively low sensitivity and severe mutual interferences of multiple stimuli detection have limited the applications of the existing e-skins. To address these challenges, inspired by the physical texture of the natural fingerprint, a novel fully elastomeric e-skin is developed herein for highly sensitive pressure and temperature sensing.
