Molecular Assembler: Nanofactories

Abstract

Molecular machines have attracted significant attentions as one of the most promising aspects of chemistry for their potential applications ever since receiving the 2016 Nobel Prize in Chemistry. The molecular assembler, also called the nanofactory, is a novel type of molecular machines that are capable of controlling the chemical reactions precisely at the microscopic level. As an analog to the macroscopic factories, nanofactories are comprised of a “transporting” part, the molecular walkers, and an “assembling” part, the molecular robotic arms. In this review, we provide a brief introduction of the research progress in recent years together with analysis on the principles of designing, constructing and operating molecular assemblers. We also summarize the prospects and challenges in the research area of molecular assemblers.
