Nanoparticles deliver chemotherapy when hit with a targeted light

Researchers at UCLA's Jonsson Comprehensive Cancer Center have developed a light-activated delivery system for chemotherapy.

Targeted gold nanoshells radiate heat to improve cancer drug effect

Researchers in China published an article in the journal Biomedical Materials demonstrating the drug-delivery potential of new gold nanoshells for cancer that also use hyperthermic effects to bring toxic cancer drugs to tumors with fewer side effects.

Alnylam, MIT team develops RNA-delivering nanoparticles for the liver

Scientists from Alnylam teamed with MIT researchers to develop a new nanoparticle platform with which to better deliver the genetic material to the liver. With MIT professor Robert Langer as one of its authors, the team published a paper in the journal  Proceedings of the National Academy of Sciences  highlighting its particles, which are inspired by the vehicles the body uses to transport cholesterol.

To fight muscular dystrophy, nanoparticles target cells that choke themselves with waste

Patients with muscular dystrophy suffer from the dysfunction of the gene that produces dystrophin, which is a protein that maintains muscle cells' performance. And a team of researchers from Washington University School of Medicine in St. Louis has found that another factor might also play a role in the weakened muscles: The cells aren't properly recycling their waste.

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.
