Nifty Nanoparticles help ‘Peel back the Curtain’ into the world of Super Small Things

Physicists at The Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to “peel back the curtain” into the world of extremely small objects – thousands of times smaller than a human hair – with major gains for medical and other technologies.

The findings, published in Science Advances, could have major implications for medical science by offering an affordable and effective solution to analyse tiny objects that are too small for microscopes to see, let alone the human eye. The work could also be beneficial for the semiconductor industry and improving quality control of the fabrication of computer chips.

The ANU technology uses carefully engineered nanoparticles to increase the frequency of light that cameras and ...

Bringing Drugs to the brain with Nanoparticles to treat Neurodegenerative diseases

After several years of research on effective and safe nanoparticles, the research team will continue laboratory testing, targeting the delivery of active ingredients to other animal models with ultimate clinical applications.

Researchers from the Institut national de la recherche scientifique (INRS) have shown that nanoparticles could be used to deliver drugs to the brain to treat neurodegenerative diseases.

The blood-brain barrier is the main obstacle in treating neurodegenerative diseases such as Alzheimer and Parkinson. According to a recent study conducted by Jean-Michel Rabanel, a postdoctoral researcher under the supervision of Professor Charles Ramassamy, nanoparticles with specific properties could cross this barrier and be captured by neuronal cells...

Study models new method to Accelerate Nanoparticles

In a new study, researchers at the University of Illinois and the Missouri University of Science and Technology modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust.

The team simulated a system that uses light to generate an electromagnetic field. Neutral nanoparticles made from glass or some other material that insulates rather than conducts electric charges are used. The nanoparticles become polarized. All of the positive charges are displaced in the direction of the field and negative charges shift in the opposite direction...

Nanoparticles take a fantastic, Magnetic Voyage


MIT engineers have designed a magnetic microrobot that can help push drug-delivery particles into tumor tissue (left). They also employed swarms of naturally magnetic bacteria to achieve the same effect (right).

Tiny robots powered by magnetic fields could help drug-delivery nanoparticles reach their disease targets. MIT Engineers have designed tiny robots that can help drug-delivery nanoparticles push their way out of the bloodstream and into a tumor or another disease site. The magnetic microrobots could help to overcome one of the biggest obstacles to delivering drugs with nanoparticles: getting them to exit blood vessels and accumulate in the right place.

Like crafts in “Fantastic Voyage” – a 1960s science fiction film in which a submarine...
