Origin of the Magnetization Anisotropy of Superparamagnetic Beads

Small, EarlyView.
Superparamagnetic beads are widely employed to study the mechanics of biomolecules with magnetic tweezers. It is shown that the residual anisotropy of the beads is due to averaging over a finite number of randomly oriented nanoparticles contained in the beads. Pinning of the anisotropic beads in the field causes low and high‐frequency noise in magnetic

Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

Small, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Light‐Guided Molecular Patterning for High‐Throughput Single‐Molecule Mechanical Characterization

Small, EarlyView.
A light‐guided molecular patterning method is presented for high‐throughput single‐molecule characterization. The approach enables scalable and accessible molecular patterning without specialized lithography equipment. Patterned surfaces are compatible with downstream biophysical assays, demonstrated by magnetic tweezers and flow‐based single‐molecule ...

Recyclable Printed Liquid Metal Composite for Underwater Stretchable Electronics

Small Science, Volume 5, Issue 5, May 2025.
This work presents a multifunctional liquid metal (LM) microdroplet‐based composite with a custom‐designed block copolymer as the matrix, optimized for printing. The composite exhibits high conductivity, stretchability, durability in dry and aqueous environments, and recyclability of LM using green solvents. These properties highlight its potential for

Twists and Turns of Liquid Crystals Unravelled by Small‐Angle Scattering

Small Methods, EarlyView.
X‐ray scattering provides valuable insights into material structure and self‐assembly. This review discusses the use of small‐ and wide‐angle X‐ray scattering (SWAXS) as well as grazing incident SWAXS for examining self‐assembled systems, especially liquid crystals.
