Abstract

Abstract: Controlling morphologies of nanomaterials such as their shapes and surface features has been a major endeavor in the field of nanoscale science and engineering, because the morphology is a major determining factor for functional properties of nanomaterials. Compared with conventional capping ligands based on organic molecules or polymers, the programmability of biomolecules makes them attractive alternatives for morphology-controlled nanomaterials synthesis. Towards the goal of predictable control of the synthesis, many studies have been performed on using different sequences of biomolecules to generate specific nanomaterial morphology. In this review, we summarize recent studies in the past few years on using DNA and peptide sequences to control inorganic nanomaterial morphologies, focusing on both case studies and mechanistic investigations. The functional properties resulting from such a sequence-specific control are also discussed, along with strengths and limitations of different approaches to achieving the goal. Graphical abstract: Image 1 Highlights: Recent progress in sequence-specific control of inorganic nanomaterial morphologies by DNA and peptides are reviewed. Mechanisms for the sequence-specific control of inorganic nanomaterial morphologies are discussed. Properties resulting from the sequence-specific controlled inorganic nanomaterial morphologies are presented. Strengths and limitations of the methods to discover biomolecular controlled inorganic material morphologies are summarized.
