Abstract An ability to develop sequence-defined synthetic polymers that both mimic lipid amphiphilicity for self-assembly of highly stable membrane-mimetic 2D nanomaterials and exhibit protein-like functionality would revolutionize the development biomimetic membranes. Here we report assembly lipid-like peptoids into stable, crystalline, free-standing self-repairing through a facile crystallization process. Both experimental molecular dynamics simulation results show assemble membranes an...
Despite recent advances in the assembly of organic nanotubes, conferral sequence-defined engineering and dynamic response characteristics to tubules remains a challenge. Here we report new family highly designable nanotubes assembled from peptoids through unique "rolling-up closure nanosheet" mechanism. During process, amorphous spherical particles amphiphilic peptoid oligomers crystallize form well-defined nanosheets before folding single-walled nanotubes. These undergo pH-triggered,...
In nature, specific biomolecules interacting with mineral precursors are responsible for the precise production of nanostructured inorganic materials that exhibit complex morphologies and superior performance. Despite advances in developing biomimetic approaches, design rules creating sequence-defined molecules lead to synthesis nanomaterials predictable unknown. Herein we report peptoids controlled highly branched plasmonic gold particles. By engineering peptoid sequences investigating...
Nanomaterials (NMs) have demonstrated enormous potential to improve agricultural production. Ten mg L–1 of customized manganese ferrite (MnFe2O4) NMs was selected as the optimal dose based on its outstanding effects promoting tomato flowering and After foliar application before flowering, MnFe2O4 increased leaf chlorophyll content by 20 percent, significantly upregulated expressions ferredoxin, PsaA, PsbA in leaves, likely serving an electron donor, leading a significant increase...
Innovative technology to increase efficient nitrogen (N) use while avoiding environmental damages is needed because of the increasing food demand rapidly growing global population. Soybean (Glycine max) has evolved a complex symbiosis with N-fixing bacteria that forms nodules fix N. Herein, foliar application 10 mg L-1 Fe7(PO4)6 and Fe3O4 nanomaterials (NMs) (Fe-based NMs) promoted soybean growth root nodulation, thus improving yield quality over unexposed control, EDTA-control, 1 5 NMs....
Polymer membranes with closely packed two-dimensionally arranged pores have been prepared at the water surface using monolayers of silica colloids as templates. The resulting porous were used templates for preparation gold rings via filling a solution precursor followed by calcinations. size can be easily controlled tuning pore templating membrane.
Tunable peptoid assembly directs the control over structure and function of Pd nanomaterial catalysts.
Partially filling a colloidal crystal can give rise to mesoscopic rings (see scheme). The liquid forms by capillary forces in the wedges around contact points between particles. is solidified, templating particles are removed, and dispersions of solid remain.
Free-standing two-dimensional (2D) organic nanomaterials are highly attractive for biological applications because of their unique structural properties and high biocompatibility. Herein, we designed synthesized a new class bright photostable membrane-mimetic 2D nanosheets from sequence-defined peptoids.

Shape-controlled colloidal nanocrystal syntheses often require facet-selective solution-phase chemical additives to regulate surface free energy, atom addition/migration fluxes, or particle attachment rates. Because of their highly tunable properties and robustness a wide range experimental conditions, peptoids represent very promising class next-generation functional for control over growth. However, understanding the origin facet selectivity at molecular level is critical generalizing...
