“…34 Zuckermann and Robinson demonstrated the stabilization of AuNPs for DNA co-adsoprbtion, 33 with Maayan and Liu reporting on the controlled assembly of AgNPs using peptoids. 35,36 Further exploration and tunability is needed in this area—this study presents one possible strategy for this purpose.…”

We demonstrate that changing the backbone between peptides, peptoids and the underexplored dual N/Cα-substituted peptoids analogues allows for control over the preferred conformation of the intrinsically disordered biomimetic oligomers. The conformation tunability is directly probed using electron paramagnetic resonance (EPR), and is shown to manifest itself in differences in the nanoparticle-oligomer hybridization propensity.

“…Their effect on metal particle assembly was studied by Tigger-Zaborov and Mayaan recently. 60 They clearly observe very small clusters of finite size, with a mass dependence on the type and length of the peptoid. At this stage, however, the reasons for the size limitations remain to be elucidated.…”

Recent experimental results using in particular small-angle scattering to characterize the self-assembly of mainly hard spherical nanoparticles into higher ordered structures ranging from fractal aggregates to ordered assemblies are reviewed. The crucial control of interparticle interactions is discussed, from chemical surface-modification, or the action of additives like depletion agents, to the generation of directional patches and the use of external fields. It is shown how the properties of interparticle interactions have been used to allow inducing and possibly controlling aggregation, opening the road to the generation of colloidal molecules or potentially metamaterials. In the last part, studies of the microstructure of polymer nanocomposites as an application of volume-spanning and stress-carrying aggregates are discussed.

“…The peptoid-controlled aggregation of Ag nanoparticles has been studied by Maayan et al They have reported using phenanthroline (Phen)/2,2-bipyridine (BP)-based peptoids (Figure ) to stabilize and further control the aggregation of Ag nanoparticles. , Specifically, quasi-spherical assemblies of Ag nanoparticles with an average diameter of ∼70 nm (Figure a) could be obtained in the presence of Pep Ag -1, a typical Phen-based peptoid consisting of one Nphen as a binding group and six Nspe groups as a hydrophobic tail. These assemblies were quite stable for months.…”

Designing Sequence-Defined Peptoids for Biomimetic Control over Inorganic Crystallization

Crystallization defines what the world is all about, ranging from biomineralization in living organisms to various materials in our lives. During these processes, peptides and proteins involved in biomineralization set excellent examples of additive-controlled crystallization. To mimic these natural systems and develop biomimetic approaches for controlling inorganic crystallization, sequence-defined peptoids, as one of the most advanced synthetic foldamers that mimic peptides and proteins, have been recently designed and explored for directing the formation of inorganic (nano)materials acting as surfactant-like soluble additives or self-assembled scaffolds due to their unique advantages (e.g., high programmability and stability). In this review, we extract the main concepts of peptoid engineering and highlight the recent advances in peptoid-controlled inorganic crystal formation. Our focus is to correlate the peptoid side chain chemistry with the morphological and kinetic control over inorganic (nano)crystal formation and to understand the principles in these biomimetic inorganic crystallization systems with respect to the predictive synthesis of organic–inorganic hybrid materials with desirable structures and physicochemical properties.
