Deciphering Anti‐Cancer Drug Efficacy Through Nanomechanical Vibrations in Living Gastric Cancer Organoids

Advanced Science, EarlyView.
This study developed an efficacy assessment platform that integrates patient‐derived gastric cancer organoids, atomic force microscopy (AFM)‐based nanomechanical vibration detection, deep learning analysis, and organoid mechanical modeling. It detects picomolar drug effects within 0.1 s signal, achieves 97% classification accuracy, and offers non ...

Bacterial spores as time capsules for cloned genes

Proceedings of the Japan Academy, Series B, 2003
Spores of bacteria Bacillus subtilis were examined for their potential for storing cloned genes in the dry state at ambient temperature for long years. A model plasmid used in this study is pTE22, which is 8.7 Kb in size and carries test Escherichia coli plasmid pBR322 in a backbone B. subtilis plasmid pHW1.

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

Advanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.
