Platinum-coated nanoparticles could power fuel cell cars

Fuel cells may power the cars of the future, but it's not enough to just make them work -- they have to be affordable. Cornell researchers have developed a novel way to synthesize a fuel cell electrocatalytic material without breaking the bank.

Breakthrough towards lab-on-chip system for fast detection of single nucleotide variations in DNA

Panasonic, core partner within imec's Human++ program, and imec today presented at the International Electron Devices Meeting in San Francisco various critical components of a biomedical lab-on-chip sensor enabling fast detection of Single Nucleotide Polymorphisms (SNPs) in DNA, such as a miniaturized pump for on-chip generation of high pressures, a micropillar filter optimized for DNA separation achieving world-record resolution, and a SNP detector allowing on-chip detection using very small sample volumes.

World's first microlaser emitting in 3-D

Versatile electronic gadgets should employ a number of important criteria: small in size, quick in operation, inexpensive to fabricate, and deliver high precision output. A new microlaser, developed at the Jozef Stefan Institute in Ljubljana, Slovenia embodies all these qualities. It is small, tunable, cheap, and is essentially the world's first practical three-dimensional laser.

Photolithography using a two-photon laser makes it possible to produce precise microstructured scaffolds for tissue engineering

The repair of organs, such as human kidney and liver, hinges on the development of three-dimensional (3D) tissue scaffolds with well-defined microstructures. Andrew Wan, Jackie Y. Ying and co-workers at the A*STAR Institute of Bioengineering and Nanotechnology have now developed a photolithography method that can be used to fabricate microstructured 3D tissue materials with high precision.

Silicon nanowire device can detect dengue viruses in less than 30 minutes

Scientists have developed a silicon nanowire-based biosensor that can detect the 'reverse transcription polymerase chain reaction' product of dengue type 2 (DEN-2) viruses in less than 30 minutes. The device utilizes silicon nanowires affixed with peptide nucleic acid (PNA) probes to recognize complementary DNA fragments of DEN-2.
