Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires to detect various molecules quickly and selectively responds to different types of solvent molecules. The device is simple, highly sensitive and could be the first step in making an easily deployable chemical sensor for the battlefield.
A new material developed at the University of Virginia can visualize even minute levels of oxygen in tumors, which are associated with increased cancer aggressiveness. This technology has great promise for being able to perform measurements of tumor hypoxia cost-effectively and could lead to more effective treatments.
Scientists have designed nanosensors that can detect specific molecules, such as poisons and proteins, in transport screening situations or patients' blood samples. The sensors use a unique interaction between two metallic nanostructures to scatter light differently, allowing for highly sensitive detection.
Researchers created DNA-based sensors using single-stranded DNA and carbon nanotubes to detect tiny amounts of specific molecules. The sensors can identify weak known odors in a strong background due to their self-regenerating surface and specificity.
Researchers will use tiny devices called nanosensors that can detect early signs of radiation-induced cell damage. The sensors, which pass easily through blood membranes, aim to avoid problems with current implantable sensors and eliminate blood sampling.
