Using fluorescent nanotubes, the researchers can detect the amount of certain substances. They use various optical setups to do this.
The nanosensors can be used to track reactions with invisible light, saving materials and time.

The Fraunhofer Institute for Microelectronic Circuits and Systems IMS and Ruhr University Bochum, Germany, have developed a process that enables a new form of signal amplification for diagnostic tests. Through the advanced use of luminescent single walled carbon nanotubes in bioanalytics, test procedures can be carried out more sensitively, quickly and cheaply. The sensors can be used for enzymatic processes. Their adaptability to different reaction conditions opens up a wide range of applications for standard methods such as ELISAs, short for Enzyme-linked Immunosorbent Assay. ...
