Modulating a Massive Set of Biomolecular Structures by Sono-Mechanical Force. [PDF]
Adv Sci (Weinh)Using low‐power ultrasound exposure, picoNewton forces are generated to release loaded drugs after unfolding secondary structures in DNA nanoassemblies. This opens a door to reversibly manipulate a large set of biomolecular structures both inside and outside cells without the damages incurred by high‐power sonications currently used in the field ...

Integrative Approaches for DNA Sequence‐Controlled Functional Materials
Advanced Functional Materials, EarlyView.DNA is emerging as a programmable building block for functional materials with applications in biomimicry, biochemical, and mechanical information processing. The integration of simulations, experiments, and machine learning is explored as a means to bridge DNA sequences with macroscopic material properties, highlighting current advances and providing ...

Advanced Functional Materials, EarlyView.Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms
Advanced Materials, EarlyView.This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.
