In this lecture we will first focus on the characteristics of the nucleation precursors and their role in the nucleation process. Experiments show that the presence of clusters has a large effect on crystal nucleation. Clusters exhibit an Ostwald ripening behavior during a crystallization cycle. With Brownian Microscopy, previously used to study the dynamics of the clusters as a whole, we obtained information on the dynamics within the clusters. Furthermore our experiments revealed that the assimilation of clusters by the growing crystals can trigger a self-purification cascade of impurity-poisoned crystal surfaces. Finally we will report on our endeavors to capture crystals at birth with more novel techniques such as 'polarized Brownian Microscopy', Confocal Depolarized Dynamic Light Scattering and TeraHertz spectroscopy.
