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.

The Gold Scientist Prize Programme

The Gold Scientist Prize programme has been established by the World Gold Council to recognise outstanding gold-based research performed by early-career scientists. Work eligible for consideration can be on-going studies, research completed in the last twelve months or a body of work compiled over several years in any materials science or related discipline where gold is central to the research.

Infrared nanocrystal LEDs can be made cheaper, compatible with silicon

Light-emitting diodes at infrared wavelengths are the magic behind such things as night vision and optical communications, including the streaming data that comes through Netflix. Cornell researchers have advanced the process of making such LEDs cheaper and easier to fabricate, which could lead to ultra-thin LEDs painted onto silicon to replace computer wiring with light waves.

Nanosensors for explosive detection

This month, the Naval Engineering Education Center heads south to check in on the progress being made on a collaborative project involving Tennessee State University and Florida Atlantic University where NEEC investigators and students are looking at ways to detect explosives using nano-sensor technology.
