| Abstract | Due to high specificity and sensitivity, fluorometric detection is one of the main detection methods applied in analytical microsystems commonly known as lab-on-a-chip (LOC). In most cases, optical instrumentation for fluorescence induction and detection is based on configuration and components ?쐀orrowed??from large laboratory instruments based on an epifluorescence microscope. As a result, the optical instrumentation surrounding lab-on-a-chip is bulky, expensive and dedicated for operation only inside laboratories. In this paper a brief discussion on fluorescence detection in lab-on-a-chip is presented. Next, novel low-cost detection instrumentation utilising noncooled CCD image sensor and semiconductor laser light source is described. The instrumentation is dedicated for operation in portable and low-cost devices for different LOC-based life science applications. Finally, an example of application of the novel method and instrumentation co-working with lab-on-a-chip for real-time PCR detection of food pathogens is briefly described. |
