Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

Functional Repurposing of Magnetic Nanoparticle‐Assisted Hyperthermia for Immune Cell Labelling and Tracking

open access: yesSmall Methods, EarlyView.
We propose mild‐MHT protocol for the quick internalization of magnetic nanoparticles (MNPs) by immune cells. The heat induced by MNPs under alternating magnetic field stimulate MNPs diffusion and cell membrane invagination, accelerating the cellular internalization of MNPs. ABSTRACT Immune cell therapies show promise in hematologic malignancies and are
