Nanosized drug delivery systems take a leap forward
19:03 November 3, 2009 PST
Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer. Read More
Magnetic nanotags detect cancer much earlier than current methods

Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method. It is forecast that earlier detection of cancer biomarkers will lead to improved survival rates among cancer sufferers. Read More
Sugar-coating nanoparticles to tempt cancer cells brings dual benefits

Researchers believe nanoparticles hold the promise of battling cancer without the damaging side effects of chemotherapy or radiation treatment. They have discovered that coating minuscule balls of iron oxide with sugar molecules not only makes them particularly attractive to resource-hungry cancer cells, it also makes them more effective by allowing them to get close to each other, but not too close to render treatment ineffective.

Gold nanoparticles used in early detection of lung cancer

Gold nanoparticles are being used by researchers in Israel in a new type of breath test to detect lung cancer in patients. Breath particulate analysis isn’t new but the scientists say this is the first time a technique has been used without the need to pre-treat the exhaled breath, delivering a quicker and less expensive diagnosis. Early detection can result in faster treatment and hopefully save lives. Around 25 percent of all cancer-related deaths are lung cancer sufferers, with estimates put at around 1.3 million people dying from the disease each year. Read More
Drink a smoothie to treat your diabetes

A yogurt-based treatment for diabetes that uses non-harmful bacteria is being tested on diabetic mice. Gut microbes that have been engineered to make a specific protein are helping regulate blood sugar in the rodents, according to research presented at the American Chemical Society conference in Washington, D.C. Scientists hope the treatment might one day provide an alternative for people with diabetes. Read More
