**5. Conclusions**

In this book chapter the preparation, structure, properties and applications of self-assembled monolayers (SAMs) in crystallization processes have been briefly reviewed. We have reviewed a variety of applications of SAMs in crystallization which can be catalogued into either pure crystallization methods or through the expression of chiral molecular interactions of SAMs.

Although two decades have passed since the discovery of SAMs, it is still a very active and broad research area that is almost impossible to review comprehensively. The fundamental questions of adsorption, structure, phases, and phase transitions have been thoroughly studied in the past, but still several issues remain unresolved. A large part of present and future work is aimed at the modification and fictionalization of surfaces by SAMs for different applications, with molecular and biological recognition being the most dynamic. Since SAMs are not so much a specific class of compounds, but rather a very flexible concept with virtually unlimited potential for applications, we expect that the area of SAMs will continue to prosper.
