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.

DNA nanorobot delivers drugs through flap that opens and closes

Researchers at the Italian Universtiy of Udine have developed small nanorobots with a "flap" designed to open and release compounds with unprecedented precision.

Harvard researchers create method to measure nano exposure for safety, delivery

Engineers have developed a method to measure the density of nanomaterials as they come into contact with cells and tissue. Beyond the safety aspect of being able to determine the amount of exposure a patient has had to nanoparticles, the method could also be used to help develop new drug delivery systems that make use of the tiny materials.

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.
