Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation

open access: yesAdvanced Optical Materials, EarlyView.
A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...

Near‐Infrared‐Driven Metal–Organic Frameworks‐Based Nanorobots for Controlled Photothermal‐Chemical Therapy Synergistic Induction of Cancer Cell Death

open access: yesAdvanced Robotics Research, EarlyView.
To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...
