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.

Stanford team finds that nanotubes catch a ride with immune cells to reach tumors

One way of bypassing the immune system to deliver drugs to a tumor site is to use the immune system itself as a delivery mechanism. And now researchers have unexpectedly found that nanoparticle-encased drugs injected into mice entered immune cells called monocytes, which then carry the treatment to the correct site.

DNA nanocages that act like viruses bypass the immune system to deliver drugs

Researchers at Harvard University's Wyss Institute have developed "smart" nanoparticles out of DNA that act like a virus to bypass the immune system's defenses and deliver drugs to a tumor.

Magnetic anesthesia: Delivering nerve blocks locally with a targeted approach

In an effort to localize the effects of anesthesia, researchers have turned to magnetic nanoparticles to target the delivery of ropivacaine in a proof-of-concept animal study.

MIT team delivers three ovarian cancer drugs with one particle

At MIT, researchers have developed nanoparticles that can carry as many as three cancer drugs at a time in a precise ratio.

Study shows nanoparticles can lose their uniform shape, size under lab conditions

As drug delivery becomes more and more dependent on nanotechnology for treatments such as chemotherapy, it's important that scientists in the field understand the implications of the tiny vehicles and what factors might play a part, for good or bad, in their delivery potential.

Nanoballoons 'pop' open to deliver cancer drugs when hit with a red laser

Researchers at the University at Buffalo have put the "pop" into drug delivery by releasing compounds from liposomes called nanoballoons that break open upon being hit with a laser.

'Computer' made with DNA nanorobots delivers compounds in live cockroach

DNA nanorobots that have proven their drug-delivering performance in early in vitro clinical trials have now demonstrated that they can do the same operations in a living cockroach.

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.

AACR: Gold nanorods aim cancer-killing lasers at the bladder

In a study presented at the American Association for Cancer Research in San Diego this week, researchers from the University of Colorado described a cancer-killing method that uses gold nanorods to target tumor cells in the bladder.
