A new nanoparticle contrast agent for MRI

New iron oxide nanoparticles could help avoid a rare side effect caused by current contrast agents.

Turning up the heat for perfect (nano)diamonds

Researchers are taking rough, defective diamonds and using high temperatures to perfect them for quantum sensing.

New sensor made from carbon nanoparticles synthesized from cellulose

By making use of a source of cellulose, such as newspapers, and sugar to synthesize carbon nanoparticles, researchers have developed a material that could be used as a sensor as its components respond to various stimuli.

Scientists to develop space-based quantum-dot spectrometer

A NASA technologist has teamed with the inventor of a new nanotechnology that could transform the way space scientists build spectrometers, the all-important device used by virtually all scientific disciplines to measure the properties of light emanating from astronomical objects, including Earth itself.

Learning how to fine-tune nanofabrication

A new computational method may improve the control of nanomaterial fabrication.

A nanofiber matrix for healing

A new nanofiber-on-microfiber matrix could help produce more and better quality stem cells for disease treatment and regenerative therapies.

Optical fibre with Einstein effect

Twisted photonic crystal fibres guide light by a mechanism similar to the bending of light rays by large celestial masses.

Better biosensors on edge

Inscribing porous, carbonized patterns into a polymer creates sensitive electrodes that detect biological molecules.

Lipid nanoparticles for gene therapy

A new review article describes these systems and their main advantages in gene therapy, such as their capacity to protect the gene material against degradation, to facilitate cell and nucleus internalisation and to boost the transfection process.

Measuring entropy on a single molecule

New research shows that a scanning-tunneling microscope, used to study changes in the shape of a single molecule at the atomic scale, impacts the ability of that molecule to make these changes.

New study of ferroelectrics offers roadmap to multivalued logic for neuromorphic computing

New research lays out a theoretical map to use ferroelectric material to process information using multivalued logic - a leap beyond the simple ones and zeroes that make up our current computing systems that could let us process information much more efficiently.

Tiny magnetic implant offers new drug delivery method

Researchers have developed a magnetic drug implant that could offer an alternative for patients struggling with numerous pills or intravenous injections.
