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.
