Infectious diseases are still a main cause of human morbidity and mortality. Advanced diagnostics is considered to be a key driver to improve the respective therapeutic outcome. The main factors influencing the impact of diagnostics include: assay speed, availability, information content, in-vitro diagnostics and cost, for which molecular assays are providing the most promising opportunities. Miniaturisation and integration of assay steps into lab-on-a-chip devices has been described as an appropriate way to speed up assay time and make assays available onsite at competitive costs. As meaningful assays for infectious diseases need to include a whole range of clinical relevant information about the pathogen, multiplexed functionality is often required for which optical transduction is particularly well suited. The aim of this review is to assess existing developments in this field and to give an outlook on future requirements and solutions.
