A team of University of Florida researchers has created tiny hybrid particles that can speedily root out even one isolated E. coli bacterium lurking in ground beef or provide a crucial early warning alarm for bacteria used as agents of bioterrorism and for early disease diagnosis. The study will appear this week in the Proceedings of the National Academy of Sciences.
"Our focus is the development of a bionanotechnology that combines the strengths of nanotechnology and biochemistry to generate a new type of bionanomaterial, which has some unique properties," said Weihong Tan, a UF Research Foundation professor of chemistry and associate director of UFs Center for Research at the Bio/Nano Interface. "Because of these properties, were able to finish the detection of a single bacterium in 20 minutes."
Bionanotechnology is a new frontier of research that combines two seemingly incompatible materials – the building blocks of life and synthetic structures – at a tiny, molecular-sized scale. Nanotechnology works with objects that are on the order of 1 to 100 nanometers; a nanometer is one-billionth of a meter, about the size of several atoms. When combined with molecular biology, the possible applications of this nano-frontier are widespread and sound like the stuff of science fiction. Scientists currently are designing microscopic "nanobots", bioprobes and biosensors that, once implanted in the human body, could perform a number of medical duties, from delivering drugs to detecting malignant cells.

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...
