Organic crystalline compounds, in many cases, have shown superior physical and chemical properties as compared to their amorphous counterparts. Such difference arises from the higher packing of molecules and long range order among them in the crystalline state. Despite such superiority, organic crystals have been less explored for biological purposes, which is due to the difficulty in reducing their size to a range suitable for biosystems. During the course of this PhD, a novel nanocrystallization method was developed that is applicable to a wide range of compounds. Organic fluorescent materials were used as the basis of the study, as they usually show distinct color change upon crystallization. In different chapters of the work, unique and novel characteristics of the nanocrystals are presented and their application for biological systems is explored.
