Instrument dedicated for development of novel sensitive optical protein/DNA/whole cell microarray diagnostic devices (biosensors) for environmental or biomedical applications. It enable to perform a highly sensitive scanning of fluorescence signals located on micrometer-sized spots of fluorescently labeled molecules attached to active biosensor surface. Instrument is equipped with powerful software for fast analysis of acquired data from individual spots with 3 µm scan resolution. It represents automated solution to innovative microarray research, genomics, proteomics and diagnostics, and is essential equipment for life science and healthcare related basic and application research.
