These results demonstrated that immobilized recombinant bacterial sensing cells could be used reproducibly in a biosensor device.
A biosensor uses biological elements - such as antibodies, proteins or cells - as the basis of a sensor.
Fiber optic biosensors have previously been employed for in situ quantitation of fluorescent chemicals or biochemical end products.
Such biosensors could detect a heart attack before a person experiences physical symptoms, researchers say.
It means funding research into biosensors - devices that detect the presence of toxic substances in the environment - and creating more effective reporting requirements for early identification of disease outbreaks.
Some century-old chemistry could have a strong impact on important issues in biosensors and other nanotech devices, according to a Purdue University research group.
Drug-delivery devices and biosensors are certainly forward-looking technologies that will have a future impact.
They have been used especially for the study of cell adhesion or protein interactions as well as for the design of biosensors on electrical devices.
One area of investigation is biosensors , the biological equivalent of the old practice of sending a canary down into a mine with to spot dangerous levels of methane gas: When the canary dies, it's time for the humans to leave.
This five-room ‘house’ is outfitted with infrared sensors, computers, biosensors , and video cameras for use by research teams to work with research subjects as they test concepts and prototype products.
