“…Heat transfer at the nanoscale is a topic which attracted a lot of attention during the last decade due to the continuous downscaling of electronic devices. 1 Self-assembled monolayers of molecules are also of growing importance in nanotechnology where they can be used as versatile tools in engineering of thermal and electrical contacts on the nanoscale, e.g., to immobilize DNA, 2 nanoparticles, 3 and for the assembly of devices based on molecular electronics. 4,5 Especially, for the latter, a fundamental understanding of the thermal transport properties is required.…”

“…Ultrathin molecular layers have developed into an important ingredient in nanotechnology. Many applications use self-assembled monolayers (SAMs) as adhesion layers for the controlled deposition of nanoparticles 1 or DNA. 2 SAMs also play a central role in the fabrication of devices based on molecular electronics, where they are deposited on substrates and coated with metal electrodes to study their electrical transport behaviour.…”

“…This study represents the first combination of DNA-based self-assembly and peptide molecular recognition to demonstrate patterned synthetic biomineralization. With continued development, the prototype described here can be used to construct simple nanoelectronic devices, such as single electron transistors24. For more sophisticated assemblies, polyvalency can be included using multiple copies of the same peptide on the 5′ and 3′ oligonucleotide ends available in the nick site of the core strand.…”

An interesting alternative to top-down nanofabrication is to imitate biology, where nanoscale materials frequently integrate organic molecules for self-assembly and molecular recognition with ordered, inorganic minerals to achieve mechanical, sensory, or other advantageous functions. Using biological systems as inspiration, researchers have sought to mimic the nanoscale composite materials produced in nature. Here, we describe a combination of self-assembly, molecular recognition, and templating, relying on an oligonucleotide covalently conjugated to a high-affinity gold-binding peptide. After integration of the peptide-coupled DNA into a self-assembling superstructure, the templated peptides recognize and bind gold nanoparticles. In addition to providing new ways of building functional multi-nanoparticle systems, this work provides experimental proof that a single peptide molecule is sufficient for immobilization of a nanoparticle. This molecular construction strategy, combining DNA assembly and peptide recognition, can be thought of as programmable, granular, artificial biomineralization. We also describe the important observation that the addition of 1-2% Tween 20 surfactant to the solution during gold particle binding allows the gold nanoparticles to remain soluble within the magnesium containing DNA assembly buffer under conditions that usually lead to the aggregation and precipitation of the nanoparticles. Keywords molecular self-assembly; structural DNA nanotechnology; molecular recognition; GEPI; oligonucleotide; oligopeptide The future of nanoscale device fabrication for diverse applications including electronics, tissue engineering, biomedical imaging, drug delivery, catalysis, and photonics will likely require 3D constructs containing inorganic nanomaterials with tunable spacings as well as integrated organic subunits. [1][2][3][4][5] Such fabrication tasks are difficult for existing top-down and bottom-up fabrication strategies. 6,7 Another approach is to imitate biology, where there are numerous examples of nanoscale materials that integrate organic molecules for selfassembly and molecular recognition with ordered, inorganic minerals to achieve mechanical, sensory, or other advantageous functions. Using biological systems as inspiration, researchers have sought to mimic the nanoscale hybrid materials produced in nature. Here, we describe a new combination of self-assembly, molecular recognition, and templating,
