Photo-immunotherapy boosts nanoparticle delivery to tumors

Hisataka Kobayashi and his colleagues at NCI's Center for Cancer Research employed a technique they call photo-immunotherapy, which uses an antibody linked to a light-sensitive compound or photosensitizer, to increase the leakiness of tumor-associated blood vessels.

Nanotechnology may enable earlier cancer diagnosis

Sangeeta Bhatia, a project leader at the MIT-Harvard Center of Cancer Nanotechnology Excellence, led the team that developed nanoparticles that can home to a tumor and interact with cancer proteins to produce thousands of biomarkers, which can then be easily detected in the patient's urine.

The nano-channel that disentangles knots

Scientists have considered a specific DNA filament model and examined its behavior within a nano-channel. They observed that by varying the channel's width it is possible to drastically change the quantity and complexity of the knots formed by the DNA.

First signals from brain nerve cells with ultrathin nanowires

Electrodes operated into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal.

A new technique to scale up production of graphene micro-supercapacitors (w/video)

UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors - devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom-thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.
