Magnetization behavior of ferrofluids with cryogenically imaged dipolar chains [PDF]
, 2008 Theories and simulations have demonstrated that field-induced dipolar chains affect the static magnetic properties of ferrofluids. Experimental verification, however, has been complicated by the high polydispersity of the available ferrofluids, and the ...

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia
Advanced Healthcare Materials, Volume 15, Issue 18, 15 May 2026.This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

4D Printing of Multimaterial Flexible Magneto‐Active Polymers
Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Magnetic Sedimentation in Aqueous Ferrofluids: for Magnetic Density Separation
, 2020 Magnetic Density Separation (MDS) is a recycling technology that can separate several different materials in a single processing step. This requires a dilute ferrofluid that ideally should remain homogeneous in external magnetic fi eld.
