Researchers at the Department of Energys Oak Ridge National Laboratory have developed a nanoscale technology for investigating biomolecular processes in single living cells. The new technology enables researchers to monitor and study cellular signaling networks, including the first observation of programmed cell death in a single live cell.
This image shows a nanoprobe, with a tip 1,000 times finer than a human hair, penetrating a cell. The probe can enter, perform a measurement in situ and be withdrawn without destroying the cell. The nanobiosensor technology provides researchers who study cell systems at the molecular level a valuable tool for monitoring the health of a single cell.
The "nanobiosensor" allows scientists to physically probe inside a living cell without destroying it. As scientists adopt a systems approach to studying biomolecular processes, the nanobiosensor provides a valuable tool for intracellular studies that have applications ranging from medicine to national security to energy production.
ORNL Corporate Fellow and Life Sciences Division researcher Tuan Vo-Dinh leads a team of researchers who are developing the nanoscale technology. "This research illustrates the integrated ‘nano-bio-info approach to investigating and understanding these complex cell systems," Vo-Dinh said. "There is a need to explore uncharted territory inside a live cell and analyze the molecular processes. This minimally invasive nanotechnology opens the door to explore the inner world of single cells".

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
