Abstract
In advanced cytometry, a fundamental challenge for rapid specific detection of rare-event micro-organisms is the autofluorescence noise from the complex biological samples. Time-gated luminescence can effectively discriminate labeled cells from autofluorescence background. Recently, a real-time true-colour time-gated luminescence microscopy system has been developed based on the synchronization of a solid-state excitation source and a super-fast optical shutter. We also developed a variety of ultra-bright silica nano-biolabels with multiple luminescence colours and controllable lifetimes in microsecond range. These developments allowed the development of an advanced cell analysis system for real-time background-free imaging and rare-event counting of microsecond-lifetime multi-colour labelled water-borne pathogens.
