Liquid-phase exfoliation using biomolecules in aqueous solution is a promising approach to obtain high quality 2D nanosheets. For example, the well-studied graphene-binding peptide, P1 (sequence HSSYWYAFNNKT), has been previously investigated and shown have good ability exfoliate graphene sheets conditions under sonication, maintaining colloidal stability. Building on this, biomolecular exfoliant assembly motif (BEAM) that features domain at one end hexagonal boron nitride (h-BN) binding...
Pathways to nanosheet selective binding peptides are presented.
Abstract Materials‐binding peptides have the capability to specifically recognize 2D nanomaterials and their modification via covalent attachment of nonnatural moieties offers exciting under‐explored possibilities tune exploit this recognition property. Here, an integrated suite experimental approaches is used reveal how conjugation a fatty‐acid chain modifies surface adsorption graphene‐binding peptide, P1, achieved using quartz crystal microbalance measurements access biomolecule free...
Modification of h-BN binding peptides can manipulate peptide orientation and overlayer viscoelasticity.
We report the effect of topographical features on gold nanowire assemblies in a vertically applied AC electric field. Nanowires 300 nm diameter ×2.5 μm long, and coated with ∼30 silica shell, were assembled aqueous solution between top bottom electrodes, where electrode was patterned cylindrical dielectric posts. Assemblies monitored real time using optical microscopy. Dielectrophoretic electrohydrodynamic forces manipulated through frequency voltage variation, organizing nanowires parallel...
The adsorption of materials-binding peptides to technologically relevant 2D nanosheets h-BN could be transformative for both property modulation and materials applications. To enhance binding, integration non-natural functionalities into the biomolecule prove important. However, very little is understood regarding impact these biomolecular structural alterations on which influence affinity surface-adsorbed structures. Here, effect fatty acid incorporation site carbon chain length...
The ability to integrate two disparate materials-binding domains into a single ligand achieve regiospecific binding would be powerful direct material assembly; however, this has proven challenging due cross-materials binding.
Lipid multilayer gratings are promising optical biosensor elements that capable of transducing analyte binding events into changes in an signal. Unlike solid state transducers, reagents related to molecular recognition and signal amplification can be incorporated the lipid grating ink volume prior fabrication. Here we describe a strategy for functionalizing with DNA aptamer protein thrombin allows label-free detection. A double cholesterol-tagged, double-stranded linker was used attach...
