Nanotechnology is an interdisciplinary field comprising materials scientists, chemists, physicists, and engineers dedicated to understanding the chemistry behind the associated synthesis, purification, modification, and applications. Already, nanotechnology has been instrumental to advances in medicine, electronics, catalysis, and cosmetics.
The work of nanotechnologists has enabled society to move from the current “Silicon Age” into a new “Nano Age.” These alternatives to Si-based technologies are expected to combine the optoelectronic properties of bulk inorganic semiconductors with the benefits of additive device manufacturing—low cost, large area, and solution-based processes.
This primer focuses on a class of nanomaterials known as colloidal quantum dots. Known for their solution processability and size-dependent optoelectronic properties, the study of colloidal quantum dots has garnered significant attention from the research community. The goal of this primer is to equip newcomers with the introductory knowledge and tools necessary to enter the field. As such, the scope of our work focuses on the synthesis and characterization of quantum dots; where possible, we point the reader to further reading specific to applications.
This book is coming soon. In the meantime, please contact your library or ACS sales representative for purchase options.

Reviewer quotes
Since I am not a chemist by training, this primer serves as a great overview of the field and a guidebook for material analysis with detailed recommendation for additional readings. Specifically, I learned a lot from the physical explanations in the last three chapters and the math models for the reaction mechanisms. I would recommend this work to my fellow lab mates, especially beginning graduate students.
