In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

New method to deliver an immune system 'uncloaking' device directly to cancer cells

Scientists at Johns Hopkins report they have designed and successfully tested an experimental, super small package able to deliver molecular signals that tag implanted human cancer cells in mice and make them visible for destruction by the animals' immune systems.

Guiding nanoparticles directly to the tumor cells

Modern anticancer therapies aim to attack tumor cells while sparing healthy tissue. An interdisciplinary team of researchers at Helmholtz-Zentrum Dresden-Rossendorf and FU Berlin has made important progress in this area: the scientists have produced tiny nanoparticles that are designed to specifically target cancer cells.

Plant-based relatives of cholesterol could boost gene-infused nanoparticle delivery

Gene-infused nanoparticles used for combating disease work better when they include plant-based relatives of cholesterol because their shape and structure help the genes get where they need to be inside cells.

Supersensitive nanomaterials hold promise for DNA analysis and next-generation drugs

In 1900, German physician Paul Ehrlich came up with the notion of a "magic bullet." The basic idea is to inject a patient with smart particles capable of finding, recognizing, and treating a disease. Medicine has pursued the magic bullet ever since.

Researchers culture human blood-brain barrier on a chip

A scrupulous gatekeeper stands between the brain and its circulatory system to let in the good and keep out the bad, but this porter, called the blood-brain barrier, also blocks trial drugs to treat diseases like Alzheimer's or cancer from getting into the brain.

Nanoparticle Trojan horse approach to clearing atherosclerotic plaques

Researchers from Michigan State University and Stanford University have designed special nanoparticles which could break down an atherosclerotic plaque from within. This could prevent heart attacks say researchers. The study titled, “Pro-efferocytic nanoparticles are specifically taken up by lesional macrophages and prevent atherosclerosis,” was published in the latest issue of the journal Nature Nanotechnology.

Sodium chloride nanoparticles offer potential for cancer therapies with fewer side effects

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles – more commonly known as salt – are toxic to cancer cells and offer the potential for therapies that have fewer negative side effects than current treatments.
