Optical Breakthrough Makes “Lab-on-a-Chip” Possible
Georgia Tech researchers have found a way to shrink all the sensing power of sophisticated biosensors — such as sensors that can detect trace amounts of a chemical in a water supply or a substance in your blood — onto a single microchip.

Based on a new theory, MIT scientists may be able to manipulate carbon nanotubes -- one of the strongest known materials and one of the trickiest to work with -- without destroying their extraordinary electrical properties.
The problem is working with them. There is no reliable way to arrange the tubes into a circuit, partly because growing them can result in a randomly oriented mess resembling a bowl of spaghetti.

Brightly fluorescent quantum dots are proving to be powerful tools for tracking the motion of cells and molecules, but their usefulness has been limited by the difficulty in getting these nanoscale beacons inside cells in a directed, controlled manner. A new simple and versatile method appears to overcome this limitation by using a specific type of enzyme to facilitate quantum dot entry into cells.

Specific applications for nanowire transistors in future "include use in building high-performance logic circuits as well as host of electronics applications on unconventional substrates, such as plastics, where such high-performance devices have not been possible," Lieber added.
Modern computers work by symbolizing data as a series of ones and zeros, binary digits known as bits. This code is most often conveyed in electronic devices via field-effect transistors or FETs, which use voltage to control the flow of current between two terminals, behaving like switches that can either be flicked one way or the other to represent a one or a zero.

Acacia Research Corporation announced today its CombiMatrix group has established a Cooperative Research and Development Agreement (CRDA) with the U.S. Air Force Research Laboratory, Human Effectiveness Directorate, Biosciences and Protection Division, Applied Biotechnology Branch (AFRL/HEPB). The CRDA will focus on "Development of a Biomonitor Device with Biomarker-based Microarrays."
"Collaborating with AFRL/HEPB through this CRDA, provides a means for us to work with investigators who are concerned with Force Health Protection. This program is the result of a Presidential Directive and is focused on monitoring the health of all Service members while they are on active duty," said Dr. David Danley, Director of Homeland Defense for CombiMatrix. "Scientists at AFRL are looking at the relationships of genetics, physiology, and environmental stressors that can reduce human performance or lead to acute or chronic health problems. Our microarray technologies will allow them to take expanded capabilities to the field where adverse events occur and palliative intervention needs to be initiated."
