Researchers Study how Bacteria Create Magnetite Nanoparticles Using MamP Protein

Researchers Study how Bacteria Create Magnetite Nanoparticles Using MamP Protein

By the time people began to look for viable routes on the ocean with the help of a compass needle in the 12th century, magnetic navigational aids had already long been in use by other living creatures. Migratory birds orient themselves with respect to the Earth’s magnetic field, but some unicellular organisms, called magnetotactic bacteria, do as well. They carry within them a chain of nanoparticles of magnetite, a magnetic mineral that functions as an internal compass. [More]

Researchers Develop Novel Technique for Separating Target Molecules from Mixed Solutions Using Magnetic Nanoparticles

Researchers Develop Novel Technique for Separating Target Molecules from Mixed Solutions Using Magnetic Nanoparticles

Separating target molecules in biological samples is a critical part of diagnosing and detecting diseases. Usually the target and probe molecules are mixed and then separated in batch processes that require multiple pipetting, tube washing and extraction steps that can affect accuracy. [More]

Physicists Accidentally Discover Sea Urchin Nanoparticles

Carbon nanotubes are hollow, cylindrical molecules that can be manipulated to give them useful properties. The nanoparticles were discovered accidentally on the rough surfaces of a reactor designed to grow carbon nanotubes. [More]
Magnetic Charge Crystallization Directly Visualized in Artificial Spin Ice Material

Magnetic Charge Crystallization Directly Visualized in Artificial Spin Ice Material

A team of scientists, led by University of Illinois physicist Peter Schiffer, has reported direct visualization of magnetic charge crystallization in an artificial spin ice material, a first in the study of a relatively new class of frustrated artificial magnetic materials-by-design known as “Artificial Spin Ice.” These charges are analogs to electrical charges with possible applications in magnetic memories and devices. The research team's findings appear in the August 29 issue of the journal Nature. [More]
Nitrogen Doped Graphene Rolled into Archimedean Nano Scrolls

Nitrogen Doped Graphene Rolled into Archimedean Nano Scrolls

Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets. The new material may have very good properties for application as electrodes in for example Li-ion batteries. [More]
