**4. Conclusions**

Co-crystallization is an effective tool and suggests one of the best auspicious routes to modify the physicochemical characteristics of the merging components. *Chemistry and Modern Techniques of Characterization of Co-Crystals DOI: http://dx.doi.org/10.5772/intechopen.108694*

There are several methods for preparing co-crystals, extending from ordinary labsize production to possibly large-scale unremitting fabrication. In this chapter, we have described the established and emerging approaches to co-crystal prepara-tion. Moreover, insights into the mechanisms of formation and techniques of characterization of co-crystals have also been presented.
