An open-source automated magnetic optical density meter for analysis of suspensions of magnetic cells and particles
Marcel K. Welleweerd, Tijmen Hageman, Marc Pichel +13
We present a spectrophotometer (optical density meter) combined with electromagnets dedicated to the analysis of suspensions of magnetotactic bacteria. The instrument can also be a…
Three-dimensional self-assembly using dipolar interaction
Leon Abelmann, Tijmen Hageman, Per Löthman +2
Interaction between dipolar forces, such as permanent magnets, generally leads to the formation of one-dimensional chains and rings. We investigated whether it was possible to let…
A thermodynamic description of turbulence as a source of stochastic kinetic energy for 3D self-assembly
Per A. Löthman, Tijmen A. G. Hageman, Miko C. Elwenspoek +4
We investigate to what extent one can use a thermodynamic description of turbulent flow as a source of stochastic kinetic energy for three-dimensional self-assembly of magnetically…
Long term observation of Magnetospirillum gryphiswaldense in a microfluidic channel
Tijmen A. G. Hageman, Marc. P. Pichel, Per A. Löthman +5
We controlled and observed individual magnetotactic bacteria (Magnetospirillum gryphiswaldense) inside a 5 μm high microfluidic channel for over four hours. After a period of const…
Kinetics of 2D-constrained orbitally-shaken particles
Dhananjay Ipparthi, Tijmen A. G. Hageman, Nicolas Cambier +4
We present an experimental study of the kinetics of orbitally-shaken macroscopic particles confined to a two-dimensional bounded domain. Discounting the forcing action of the exter…
