Advances in development of lab-on-chip devices, which shrink and potentially simplify laboratory tests like DNA analysis, have largely been tempered by the inherent complexity of the systems they are trying to replace. DNA analysis usually requires a laboratory full of instruments and several days to obtain results.
But now a team of researchers at Arizona State University report that they have made several advances in the area of microfluidic component design, fabrication and integration, bringing the technology to the point where DNA analysis could be done simply and in significantly less time than required today. The researchers are borrowing their ideas from what has become the king of small-scale integration – microelectronic integrated circuits (IC).
"Weve basically taken some of the primary ideas of electronic integration and applied them to microfluidic devices. This new platform is called microfluidic IC," said Robin Liu, project manager at the Center for Applied Nano-Bioscience (ANBC) at the Arizona Bio Design Institute. "The novelty here is instead of having electrons flow between electronic chips, with microfluidics we have very tiny amounts of fluid moving between chips."

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
