Soft Micromanipulation Robot for Real‐Time Adaptive Multimodal Operation

Advanced Science, EarlyView.
This manuscript proposes a soft micromanipulator robot (SMR) for “full‐angle” precision biomedical operations. Bio‐inspired SMR achieves omnidirectional motion, micrometer precision, and multimodal capabilities including aspiration, transfer, rotation, assembly, injection, and cutting.

High‐Resolution Multiplexed Sequencing of Single‐Cell Full‐length Transcriptome Via Combinational Barcoded Tn5 Transposon Insertion

Advanced Science, EarlyView.
CBTi‐seq is reported, leveraging Tn5 transposase‐mediated molecular assembly of combinatorial barcodes and UMIs for high‐resolution multiplexed sequencing of the full‐length transcriptome in single cells. This approach achieves molecular resolution by end‐to‐end sequencing, enabling reconstruction of splice variants and accurate quantification of ...
