A review on laser-induced crystallization from solution

Abstract

Crystallization is abound in nature and industrial practice. A plethora of indispensable products ranging from agrochemicals and pharmaceuticals to battery materials, are produced in crystalline form in industrial practice. Yet, our control over the crystallization process across scales, from molecular to macroscopic, is far from complete. This bottleneck not only hinders our ability to engineer the properties of crystalline products essential for maintaining our quality of life but also hampers progress toward a sustainable circular economy in resource recovery. In recent years, approaches leveraging light fields have emerged as promising alternatives to manipulate crystallization. In this review article, we classify laser-induced crystallization approaches where light-material interactions are utilized to influence crystallization phenomena according to proposed underlying mechanisms and experimental setups. We discuss non-photochemical laser-induced nucleation, high-intensity laser-induced nucleation, laser trapping-induced crystallization, and indirect methods in detail. Throughout the review, we highlight connections amongst these separately evolving sub-fields to encourage interdisciplinary exchange of ideas.

“…Here, we exploit two different implementations of the hardware: laserinduced cavitation and fluorescence-PIV, achieved with minimal modifications to the microscope assembly. The validation of this working setup along with the customizations can prove to be beneficial for a multitude of research applications [30].…”
