High-content screening microscopy (HCS) combines automated fluorescence imaging with advanced image analysis to extract quantitative, multiparametric data from high-throughput cells. Unlike conventional microscopy, which typically involves manual sample handling and limited field of view analysis, HCS systems are designed to map entire multiwell plates quickly and reproducibly. These systems use automated tables, robot-controlled fluid handling, and advanced optics (often including confocal or spinning disk technologies) to capture high-resolution images across multiple channels. The resulting images are processed using machine learning or rule-based algorithms to quantify complex cellular phenotypes such as changes in morphology, protein localization, or cell cycle status. This integration of imaging and analysis allows researchers to study thousands of experimental conditions in parallel, making HCS an indispensable platform for large-scale drug discovery, functional genomics, and systems biology. An HCS microscope enables systematic, large-scale functional screening at the cellular level, allowing the rapid assessment of the effects of genetic disorders, chemical compounds or environmental changes on important biological processes such as pore formation in membranes, protein transport and organelle dynamics. For the planned experiments, the HCS microscope must combine high spatial resolution (to resolve subcellular structures such as nuclear pore complexes (NPCs), membrane pores, and protein aggregates involved in mitochondrial dynamics and cell death) with minimal photobleaching and low phototoxicity to ensure that live cell imaging is possible over longer periods of time. Fast detection speeds are also critical to detecting fast and transient cellular events. Many of the intended applications also require high temporal resolution to visualize dynamic processes without compromising field of view or signal integrity. The experiments also require multiparametric analysis across multiple fluorescence channels to enable simultaneous tracking of multiple cellular events. It is important that the system supports the light-controlled activation of optogenetic tools and offers the flexibility to manipulate laser power and illumination patterns to enable precise spatial and temporal control of cell behavior in selected areas of interest. The complete system is seamlessly integrated to ensure smooth operation, maximum flexibility in system configuration and setup, user-friendly interface and optimal use of space. The system also offers the highest level of automation, including automatic image alignment, automatic dosing and removal of lens immersion fluid, and automatic plate handling across all components, including removal of the lid. In order to achieve a fast detection, the system is equipped with two cameras. To ensure time-efficient imaging of the target locations within the Well plates, the microscope may combine a fast low-resolution pre-scan with higher-resolution imaging and/or time-lapse imaging of areas identified from that pre-scan (e.g. to identify certain features or rare events). Since most of the experiments planned for this microscope are based on multicolor staining, the microscope can efficiently suppress blood circulation and crosstalk without having to constantly change the filter between the acquisitions.
