Nanoparticle size: Smaller is better, up to a certain point

The optimal size of  nanoparticles  is 50 nanometers, smaller than the 100- to 200-nm ones deployed today, concludes a study by University of Illinois researchers.

Encapsulated Alzheimer's, Parkinson's-treating growth factors implanted directly in the brain

Scientists in Spain have now developed small particles with the ability to encapsulate growth factors when implanted in the brain, which could ultimately reverse the effects of these diseases by spurring the growth of new, healthy neurons.

Stealthy, DNA-based 'nano-cocoons' deliver cancer-killing payloads

Researchers at NC State University and the University of North Carolina have developed a DNA-based delivery vehicle capable of acting as a Trojan horse in cancer cells. Using DNA as a cage instead of synthetic materials makes the vehicle less toxic to healthy cells and allows for the attachment of precise targeting mechanisms.

With Roche's Herceptin, green tea component doubles drug accumulation in cancer cells

A team from the Singapore-based Agency for Science, Technology and Research has found that a component of green tea has the potential to act as a nano-sized drug delivery vehicle to encapsulate proteins used to fight cancer.

Flat nanosheets roll drugs up and release them on command

Researchers at the Okinawa Institute of Science and Technology in Japan have developed what they call a nanosheet that is capable of holding drugs and is also reproducible for a number of different treatments.

Which vehicle works best? High-speed testing gives drug delivery a boost

Finding the right delivery vehicle for a drug, one that will let the drug reach its full potential, is an invaluable prospect. And now MIT engineers have developed a way to test these vehicles quickly in vivo to determine which of them will be most efficient in delivering its payload.

Purdue team recreates tumor microenvironment to study cancer nanomed delivery

A Purdue University team has created a new chip that promises to help test how cancer-killing nanoparticles react in a tumor environment. Because different nanoparticles perform vastly different functions in drug delivery, it's important to determine early on what kind of effect they will have on a tumor and what it would take to improve their outcome.

X-ray-triggered liposomes deliver precisely controlled cancer treatment

Combining chemotherapy and radiotherapy would be ideal for cancer treatment, but administering both at the same time can lead to unacceptable and often deadly levels of toxicity. Now researchers have developed liposomes that contain a chemotherapy drug activated by radiotherapy, offering both cancer-killing power and a targeted approach in a more controlled manner.

UO, Berkeley team tailors ultrathin peptoid nanosheets for delivery using oil and water

Creating the materials used for some of the most intricate nanostructures in drug delivery sometimes requires going back to the basics. In the case of researchers at the University of Oregon and the Berkeley Lab, this meant looking at the interaction between oil and water, developing nanosheets that could be used to compile delivery vehicles down the road.

Organic nanoparticles offer 'complete package' against cancer: delivery and imaging

Nanoparticles come in many shapes and sizes, each specifically designed to play a precise role in cancer treatment. And now, researchers from UC Davis have created nanotechnology with the ability to perform multiple tasks and the ultimate goal of destroying tumors.
