The synthesis of particle takes place in a microheterogeneous environment in the presence of oil and surfactant. The dispersed nanodrop formed acts as a stable phase in a microreactor and then dispersed in a second phase known as continuous phase which is used for the preparation of nanomaterials with phase selection. 

The uniform and well-defined fluid flow conditions of microreactors also provide opportunities to better control the dynamics of nanomaterial synthesis. Kroon et cd. [102] studied the eSects of mixing on the coagulation processes of CdS NPs vrithout a stabilizer using simple predpitation reaction of CdN03 and Na2S. Their results indicate that the use of a static micromixer and laminar flow reactor could produce a dispersed CdS NP solution that is stable for hours. In contrast, the batch reactor... 

Nonaqueous IL microemulsions were also used as catalysts to improve reaction efficiency. Gayet et al. established an IL-in-oil microemulsion system with benzylpyridinium bis(trifluoromethanesulfonyl)imide ([BnPyrJNTfj), TX-lOO, and toluene, in which the Matsuda-Heck reaction between methoxybenzene diazotate and 2,3-dihydrofuran took place [46]. The reaction yield in this IL-in-oil microemulsion was twice as high as that in neat ILs. The results provided a basis for designing a nonaqueous IL microemulsion microreactor and also showed that nonaqueous IL microemulsion might have good prospects of applications in biocatalysis and nanomaterial synthesis.
