Gold nanoparticles on orthopedic implants prevent infection

Gold nanoparticles help prevent the formation of antibiotic resistant biofilm on the surface of orthopedic implants, researchers at the Shanghai Institute of Ceramics discovered.

MicroRNA delivery specialist Microlin Bio nears $30 million IPO

MicroLin Bio, a developer of microRNA treatments for cancer, is expected to price its $30 million IPO on the Nasdaq this week. Delays and share dilution have taken some of the shine off the event, but investors enthiusiam will ultimately hinge on the fate of its proprietary nanoparticle delivery technology.

Nanocarriers that harness fungus traits could deliver drugs to brain

Investigators have designed silicon nanoparticles that could be capable of penetrating the blood-brain barrier. The scientists presented their findings during a symposium at the American Society for Microbiology annual meeting on May 17.

MIT researchers deliver low doses of siRNA to lung endothelial cells

One of the chief drawbacks of RNA interference therapies so far has been the difficulty of delivering small interfering RNA to cells outside the liver. That's why a newly reported breakthrough in delivering siRNA to endothelial cells in the lung and other organs is a big deal.

X-ray-activated nanoparticles release cancer-killing light deeper into tissue

Researchers at the University of Texas at Arlington found that nanoparticles they were studying for radiation detection in the security arena could produce a toxic byproduct able to damage cancer cells.

Magnetic nanoparticle hyperthermia with an antibody is effective in breast cancer cells

Dartmouth researcher Jack Hoopes has demonstrated that magnetic nanoparticle hyperthermia could be a possible treatment for breast cancer, as he presented in a new preclinical study at the American Association for Cancer Research annual meeting in San Diego.

Water excited by infrared light melts nanoparticles to release drugs

Many drug delivery systems incorporate complex compounds designed to deliver precise doses to a desired target. Researchers at the University of California, San Diego, though, have developed a platform that uses as its main delivery function a substance familiar to us all: water.

The year in nanotech drug delivery

Here at FierceDrugDelivery, we write often about innovations in nanotechnology as it becomes more and more important in the delivery field. These advances are mostly in the very early stages, but they're still promising as the delivery field moves even further into the nanoscale.

Clumps of gold nanoparticles retain heat or drugs to kill cancer cells

Researchers have developed gold nanoparticles that could act as a cancer treatment by heating up and destroying tumor cells when they absorb near-infrared light. And the scientists have made the so-called plasmonic particles in a way that can be reproduced in bulk.

Delivery method uses a cancer cell's power source to trigger drug release

Every living cell stores or spends its energy in the form of adenosine triphosphate, or ATP, which has historically been known as the "molecular unit of currency." And using this molecule as a targeting mechanism for cancer drugs, scientists in North Carolina have developed a way to trigger the release of chemotherapy within the offending cells.
