New ultra-thin electronic films have greater capacity

The development of a new combination of polymers associating sugars with oil-based macromolecules makes it possible to design ultra-thin films capable of self-organization with a 5-nanometer resolution. This opens up new horizons for increasing the capacity of hard discs and the speed of microprocessors.

Erzeugung extremer UV-Strahlung mit Lasern an Nanostrukturen

Wissenschaftlern der Uni Goettingen und der Uni Leipzig ist es gelungen, die Erzeugung von extrem ultravioletter Strahlung an Nanostrukturen mit Laserpulsen in ein neues Licht zu ruecken. Die Forscher konnten einen bisher in grossen Teilen unverstandenen physikalischen Mechanismus aufklaeren.

Plasmonic nanobubbles plus chemotherapy equals single-cell cancer targeting

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles", researchers are developing new methods to inject drugs and genetic payloads directly into cancer cells. In tests on drug-resistant cancer cells, the researchers found that delivering chemotherapy drugs with nanobubbles was up to 30 times more deadly to cancer cells than traditional drug treatment and required less than one-tenth the clinical dose.

New breast implant deters cancer cells

A new type of implant developed by researchers at Brown University may be able to deter breast cancer cell regrowth. Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy cells into breast tissue.

New technique detects trace levels of new class of cancer biomarkers

A team of investigators from the Northwestern University Center for Cancer Nanotechnology Excellence (Northwestern CCNE) has developed a rapid, array-based technology using gold nanoparticles that is capable of detecting miRNAs at levels as low as 1 femtomolar (about 30,000 molecules in a drop of blood).

Nanoparticle factories churn out proteins - Could manufacture cancer drugs at tumor sites

Drugs made of protein have shown promise in treating cancer, but they are difficult to deliver because the body usually breaks down proteins before they reach their destination. To get around that obstacle, a team of researchers has developed a new type of nanoparticle that can synthesize proteins on demand. Once these "protein-factory" particles reach their targets, the researchers can turn on protein synthesis by shining ultraviolet light on them.

Delivering nanoparticles to the cell nucleus

While a great deal of the potential for nanotechnology to improve cancer therapy lies with the ability of nanoparticles to deliver drug payloads directly to tumors, an equally important consideration is whether nanoparticles can then get their drug payload to their intended target inside tumor cells. Now, a team of investigators has developed star-shaped nanoparticle that can deliver a drug directly to a cancer cell's nucleus - an important feature for many potential anticancer therapies.

Solar power to dye for

Researchers at the University of Turku believe that flexible, lightweight and inexpensive dyes could be used to harvest the power of the sun rather than our relying on costly and fragile semiconductor solar panel that use crystalline silicon.

New nanostructure for batteries keeps going and going...

For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led by materials scientist Yi Cui of Stanford and SLAC has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.
