The achievement of rapid multiplexed protein imaging is limited by the use of stimulating reagents, extensive incubating and washing steps, and the low fluorescence intensity of targets. In this study, sequentially‐activated DNA tags are developed and combined them with primary antibodies using signal enhancement strategies to create sequentially‐activated antibodies (SAAs). These SAAs enable rapid,...
Neurons can be modified to express light‐sensitive proteins for enabling stimulation with a high spatial and temporal resolution, but such techniques require gene transfection and systematical implantation. Here, a black phosphorus nanosheet‐based injectable strategy is described for wireless neural stimulation both in vitro and in vivo without cell modifications. These nanosheets, with minimal invasiveness,...
In article number 1900006, Zi Chen, Peng Shi, and co‐workers develop a tissue‐engineered transformable swimming robot, which can be remotely controlled by near‐infrared light to change its shape (bend and unbend) and switch locomotive functionality (stop and swim, respectively). With the unprecedented controllability and responsiveness, the transformable robot can be implemented for programmed eradication...
Many living organisms undergo conspicuous or abrupt changes in body structure, which is often accompanied by a behavioral change. Inspired by the natural metamorphosis, robotic systems can be designed as reconfigurable to be multifunctional. Here, a tissue‐engineered transformable robot is developed, which can be remotely controlled to assume different mechanical structures for switching locomotive...
