High-content screening technology is mainly based on automated digital
microscopy and flow
cytometry, in combination with IT-systems for the analysis and storage of the data. "High-content" or visual biology technology has two purposes, first to acquire spatially or temporally resolved information on an event and second to automatically quantify it. Spatially resolved instruments are typically automated
microscopes, and temporal resolution still requires some form of fluorescence measurement in most cases. This means that a lot of HCS instruments are (
fluorescence) microscopes that are connected to some form of image analysis package. These take care of all the steps in taking fluorescent images of cells and provide rapid, automated and unbiased assessment of experiments. == Development of technology ==
