Quantum Dot Template for Fast and Simultaneous Detection of Different Infectious Agents

摘要

A method and a device for detecting the presence of a predetermined substance, in which a quantum dot is produced on a substrate. The quantum dot emits a radiation at a predetermined wavelength, and is covered with a surface layer to which the predetermined substance attaches. A deviation of the value of a parameter related to the radiation is produced when the predetermined substance attaches to the surface layer. This deviation can be detected to thereby sense the presence of the predetermined substance.
