DETECTION SYSTEM COMPRISING A LIGHT GUIDE FOR DIRECTING RADIATION TO A REACTION CHAMBER

摘要

A system for detecting small quantities of agent such as DNA in a larger volume of substance is disclosed. The system includes a radiation emitter arranged so as to emit radiation on to a quantity of substance containing the agent. The incident radiation excites the agent causing it to emit radiation detectable by suitable detection means. The incident and emitted radiation are directed by a light guide that also acts so as to contain the substance being monitored.
