Recent developments in science and technology are linked to an improved understanding of materials and their properties. Such advances allow for steadily smaller and lighter device architectures used in different aspects of our daily lives. A decrease in the size of practical devices makes them easier to handle and reduces the material cost for their fabrication, which is the key to sustainable technological achievements.

In this context, classical materials are unsuitable for such applications as quantum effects change the inherent material properties for reduced dimensionality. Various materials have been reported to show new and promising properties compared to their bulk counterparts if at least one dimension is reduced to nanometer size. Such materials known as “low dimensional materials” are used for various applications in sensing, electronics, catalysis, and other diverse fields. Moreover, various techniques for their preparation have been reported, yielding in single macromolecular structures (e.g., micromechanical exfoliation) or ensembles of nanoparticles in a dispersion (e.g., liquid-phase exfoliation). However, a significant challenge of current research in this field lies in the development of reproducible, precise, and, at the same time, scalable routines for processing nanoscopic structures.

Therefore, this collection aims to present various established and innovative methods for the identification, preparation, and processing of nanomaterials or low-dimensional materials. Overall, this collection of methods in the form of video articles is aimed at helping researchers choose methods according to their research needs, thereby leading to rapid progress in this field.
