This dissertation investigates the non-display application of liquid crystal materials. The novel areas of application for liquid crystal materials, especially in biomedical imaging and microscopy, required further studying of the conventional liquid crystals' properties and exploring the area of modified liquid crystal materials. Stressed liquid crystals and dual-frequency nematic liquid crystals were investigated for liquid crystals' advanced applications.Stressed liquid crystals' characteristics and electro-optical properties are presented, and material production step-by-step guidance is described.Dual-frequency nematic liquid crystal materials, suitable for inexpensive, fast tunable advanced liquid crystal based devices, are researched. The electro-optical response and orientational order parameters are studied for the proposed liquid crystal material over a non-conventional range of layer thicknesses. The studied properties of dual-frequency nematic liquid crystals and advanced understanding of their behavior under applied electric field were used to create a fast tunable optical filter design. The complete process from filter design, characterization, and production to the application into advanced microscopy of the live cells is depicted in the manuscript.The novel filter application to biomedical microscopy, particularly total internal reflection fluorescent microscopy, is described. The fluorescent microscopy of live RBL -2H3 cells during the modeling of the cell-to-cell interaction process using the developed filter is presented. The live cell line characteristics are measured and reported as well.
