In this study, we report the microfluidic-based synthesis of a multifunctional Janus hydrogel particle with anisotropic superparamagnetic properties and chemical composition for the bottom-up assembly of hydrogel superstructures. In a uniform magnetic field, the resulting Janus magnetic particles fabricated in the present method exhibit chainlike or meshlike superstructure forms, the complexity...

tion. Conversely, a semi-rigid, optimized acentric organization results in coherent second harmonic emission at the supramolecular level, the corresponding intensity from the dendrimer solution being almost proportional to Nmonomerábmonomerñ. The Nmonomer dependence assumes a linear additive model, whereby the individual sub-units follow an interaction-free oriented gas behavior. We have, there...

We report that hemozoin nanocrystals demonstrate superparamagnetic properties, with direct measurements of the synthetic hemozoin magnetization. The results show that the magnetic permeability constant varies from μ = 4585 (at -20 °C) to 3843 (+20 °C), with the values corresponding to a superparamagnetic system. Similar results were obtained from the analysis of the diffusion separation of natu...

Superparamagnetic iron oxide nanoparticles have been coated with a low affinity CXCR4 receptor antagonist to give high multivalent binding construct.

Analytical calculations based on finite-size spin-wave theory and Monte Carlo (MC) simulations are performed to investigate the validity of the well-known relation m(H,T ) = M(H, T )BD[M(H,T )NH/T ] between the induced magnetization m of the magnetic particle and its intrinsic magnetization M for the Ising and isotropic classical models [BD(x) is the Langevin function, D is the number of spin c...
