Real‐Time Force Monitoring of Electrically Stimulated 3D‐Bioengineered Muscle Bioactuators Using Organic Sensors with Tunable Sensitivity

open access: yesAdvanced Intelligent Systems, EarlyView.
The integration of sensing elements in bioengineered actuators is key to obtain real‐time information about their performance and further control/automation. By coupling flexible organic field‐effect transistor to a skeletal muscle actuator we demonstrate the feasibility to record in real‐time its contractile behavior when stimulated by electrical ...

Synthesis of a Molecular Tweezer Based on Norbornadiene Framework: Unexpected Stereoselectivity

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A new type of Klarner's molecular tweezer was synthesized through annulation of an α‐amino ketone. Surprisingly, the reaction takes place stereoselectivity though the initial amino ketone is racemic. This tweezer comprises two near‐parallel flat aromatic rings as pincers, each bearing two methyl ester groups, and a pyrazine unit as the tether ...
