Joint subarray acoustic tweezers enable controllable cell translation, rotation, and deformation

Nature Communications
Contactless microscale tweezers are highly effective tools for manipulating, patterning, and assembling bioparticles. However, current tweezers are limited in their ability to comprehensively manipulate bioparticles, providing only partial control over ...

Interfacial Yield Stress Response in Synthetic Mucin Solutions

Advanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

An Introduction to Magnetic Tweezers

, 2023
AbstractMagnetic tweezers are a single-molecule force and torque spectroscopy technique that enable the mechanical interrogation in vitro of biomolecules, such as nucleic acids and proteins. They use a magnetic field originating from either permanent magnets or electromagnets to attract a magnetic particle, thus stretching the tethering biomolecule ...

Effective Manipulation of Water Droplets on Open Superhydrophobic Glass Surfaces by Using a Triboelectrically Charged Polytetrafluoroethylene Rod on the Back Side of These Surfaces

Advanced Materials Interfaces, EarlyView.
The movement of pure water droplets on a superhydrophobic glass surface is precisely controlled through electrostatic manipulation using a polytetrafluoroethylene (PTFE) rod from the opposite side. With just a few seconds of triboelectric charging, the PTFE rod directs droplets, achieving acceleration over 10 000 mm s−2.

Improvement of Electrochromic Stability of Viologen‐Based Ionic Gel by Layered Metal–Organic Frameworks

Advanced Materials Interfaces, EarlyView.
Metal–organic framework doped viologen‐based ionogel electrochromic device demonstrates superior performance including homogeneous chromatic transition, enhanced coloration efficiency, and exceptional cycling stability. These advancements originate from dual mechanisms: 1) physical confinement effect effectively suppressing viologen molecular ...

Multi-reservoir enhanced loading of tweezer atom arrays [PDF]

arXiv
We introduce a species-independent method for improved loading into a single-atom optical tweezer array, utilizing iterative loading with multiple reservoir tweezers. Demonstrated with dual wavelength tweezer arrays of $^{88}$Sr atoms, our approach achieves a 96$\%$ loading rate after four reload cycles.

Theoretical and Experimental Investigation of the Ligand‐Directed Assembly and Photovoltaic Performance of PbSe Nanorods

Advanced Materials Interfaces, EarlyView.
This study delves into the critical role of ligand type on morphology, photophysical behavior, and optoelectronic performance of PbSe Nanorods (NRs). A combination of computational modelling and experimental techniques reveals that EDT‐capped PbSe NRs exhibit well‐ordered packing with strong interfacial coupling and improved optoelectronic performance.
