Iron(II) coordination complexes with panchromatic absorption and nanosecond charge-transfer excited state lifetimes.

TL;DR: This finding shows how ligand design can extend metal-to-ligand charge-transfer-type excited state lifetimes of iron(ii) complexes into the nanosecond regime and expand the range of potential applications for iron-based photosensitizers.
Journal ArticleDOI

Internal Magnetic Structure of Nanoparticles Dominates Time-Dependent Relaxation Processes in a Magnetic Field

TL;DR: In this article, the influence of internal nanoparticle (intracore) magnetic domain structure on relaxation remains unexplored, and dramatic differences observed among the specific loss power of three magnetic iron oxide nanoparticle constructs having comparable size and chemical composition.
Journal ArticleDOI

Spin canting across core/shell Fe 3 O 4 /Mn x Fe 3−x O 4 nanoparticles

TL;DR: It is demonstrated that intraparticle effects can induce spin canting throughout a MNP via the Dzyaloshinskii-Moriya interaction (DMI), and results illuminate how core/shell nanoparticle systems can be engineered forspin canting across the whole of the particle, rather than solely at the surface.
Journal ArticleDOI

Hierarchical self-assembly and optical disassembly for controlled switching of magnetoferritin nanoparticle magnetism.

TL;DR: Rec recombinant ferritin protein cages encapsulating Fe(3)O(4)-γ-Fe(2)O (3) iron oxide (magnetoferritin) nanoparticles and photodegradable Newkome-type dendrons self-assemble into micrometer-sized complexes with a face-centered-cubic (fcc) superstructure and a lattice constant of 13.1 nm.
Journal ArticleDOI

A new tool to attack biofilms: driving magnetic iron-oxide nanoparticles to disrupt the matrix

TL;DR: This work uses magnetic iron oxide nanoparticles (MNPs) in combination with magnetic fields to damage the biofilm matrix and cause detachment, achieving up to a nearly 5 log10 reduction in biofilm bacteria after treatment with 30 mg mL-1 of 11 nm MNPs using a magnetic field.
