Piezoelectric‐Enhanced Oriented Cobalt Coordinated Peptide Monolayer with Rectification Behavior

Abstract

A metal‐coordinated α‐helical peptide monolayer shows exceptional vectorial electron transfer. It also displays rectification behavior whereby an alternating current signal is successfully turned into a direct current signal by the mono­layer acting as an electric rectifier. The monolayer can simply be fabricated the piezoelectric field generated from an in‐situ nanogenerator, which opens up a wide range of applications.

Peptide-based self-assembled monolayers (SAMs): what peptides can do for SAMs and vice versa

“…This type of system holds great potential to be used in molecular memories, nonlinear molecular electronic devices, and biosensors. 164 The remarkable work of Yasutomi and collaborators presents the fabrication of highly ordered bicomponent SAMs as part of a molecular photodiode system able to switch photocurrent direction by choosing the wavelength of irradiating light. 60 This system includes two types of helical peptides with an alternating sequence of L-or D-leucine and a-aminoisobutyric acid carrying two different sensitisers: SSL16ECz carries a disulfide group at the Nterminus and a N-ethylcarbazolyl (ECz) group at the C-terminus; meanwhile, Rul16SS carries a tris(2,2 0 -bipyridine)ruthenium(II) complex (Ru group) at the N-terminus and a disulfide group at the C-terminus (Fig.…”

Simultaneous Passivation and Encapsulation of Black Phosphorus Nanosheets (Phosphorene) by Optically Active Polypeptide Micelles for Biosensors

“…It is well-known that peptides can undergo self-assembly and form ordered nanostructures. These assemblies can be stabilized by interpeptide and hydrogen bond networks. , Similarly, as the copolymer 1 contains polypeptide unit, and thus it is supposed to form self-assembly giving rise to well-defined nanostructures, e.g., micelles. These micelles of copolymer 1 acted as nanocontainers to capture the BP nanosheets under mechanical shearing assisting the disintegration of micelles into aggregated copolymer chains with no well-defined shape, and thereby allowing BP nanosheets to come in contact with the inner helical compartment.…”
