But one of the major limitations of these technologies is their inability to detect the presence of only a few cancer cells.
Now, a research collaboration between the University of Missouri-Columbia and Mexico's Universidad de Guanajuato shows that pulsed photoacoustic techniques, which combine the high optical contrast of optical tomography with the high resolution of ultrasound, can do just that, in vitro. Most cancer cells are naturally elusive, so they used a photoacoustic enhancer to detect them.
New developments are necessary, the researchers say, to be able to properly use photoacoustic techniques to recognize different cancer cell types inside the human body or in blood or tissue samples.
Article: "An experimental and theoretical approach to the study of the photoacoustic signal produced by cancer cells" is published in AIP Advances.

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.

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...
