Microchip coated with cells gives insight into nanoparticle penetration

MIT professor and entrepreneur Robert Langer is behind another innovative nanotechnology application for drug delivery, this time helping develop a model that could help researchers understand the way nanoparticles penetrate blood vessel walls.

URI scientist collects $1.3M to blast tumors with nanoparticles

A University of Rhode Island researcher won a National Institutes of Health grant of $1.3 million to further study the use of cancer-targeting copper sulfide nanoparticles for breast cancer.

Statins delivered with HDL nanoparticles reduce risk of second heart attack, stroke

High-density lipoproteins are a key component in the transportation of molecules such as cholesterol and fats inside the body. And by using a synthetic nanoparticle version of these natural vehicles, researchers have found a way to deliver drugs to the heart that could potentially prevent repeat heart attacks or stroke.

'On-off' switch in disguised nanoparticles shows delivery potential

A nanoparticle with a specific code mechanism for release could allow drug-carrying vehicles to issue their payload upon contact with a specific biomarker. Now, researchers have developed a nanoparticle that uses coded DNA as this kind of "on-off" switch.

Vaccine nanoparticles offer shake-and-bake field delivery

To be able to make vaccines on site simply and effectively would greatly benefit remote areas that are often hampered by both distance from the source of vaccines and the difficulty of refrigeration. And researchers at the University of Washington have developed a nanotech delivery solution that could give vaccinators a leg up in the field.

How a single nanoparticle delivers two drugs separately to kill cancer cells

Two birds with one stone? How about two drug targets with one delivery vehicle? Researchers in North Carolina have developed a single nanoparticle capable of carrying two separate drugs to two different locations in a cancer cell. The aim is to program the delivery in such a way that maximizes the efficiency of each drug.

Study: 'Worm-shaped' nanoparticles best at infiltrating breast cancer

Often when using nanoparticles to target and penetrate cancer cells, the shape of the tiny drug-carrying vehicles is crucial to their performance. Researchers have now found evidence that "worm-shaped" nanoparticles may be more effective than spheres at delivering cancer drugs to breast cancer.

Dual-wave approach clears path for cancer drug delivery

To get through a dense jungle, you'll need to clear a path. Similarly, to get past a thick network of scaffolding that often prevents drugs from reaching cancer cells, UCLA researchers have developed nanoparticles capable of clearing a path for drugs to pass through to a tumor.

DNA-delivering patch spurs bone growth

A small patch that delivers DNA-loaded nanoparticles may be the next step in bone regeneration, offering a new option for patients currently receiving repeated, painful injections.

Iron oxide nanoparticles monitor cancer drug release in real time

Researchers at the University of New South Wales have developed iron oxide nanoparticles capable of both delivering cancer drugs and precisely measuring their release in real time.
