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.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
