Abstract: Devices, systems, and methods for applying a dielectrophoretic force on a particle include: a cell defining at least one channel for confining the particle; and a first electrode and a second electrode electrically isolated from the first electrode, at least one of the first and second electrodes being formed from a two-dimensional (2D) material providing an atomically sharp edge. The first and second electrodes are arranged sufficiently close to one another and sufficiently close to the channel such that application of a sufficient voltage across the first and second electrodes generates an electric field in at least part of the channel, the electric field having an electric field gradient sufficient to apply the dielectrophoretic force on the particle in the channel.

Abstract: This document relates to methods and materials for detecting the presence or absence of misfolded polypeptides in a sample. For example, methods and materials for amplifying a sample (e.g., a biological sample or an environmental sample) such that misfolded polypeptides present in the sample can aggregate to form fibrils and/or globular polypeptide aggregates and contacting the amplified sample with a solution containing metal nanoparticles (e.g., gold nanoparticles) or one or more organic dyes (e.g., Congo Red) to detect the presence or absence of fibrils and/or globular polypeptide aggregates are provided. In some cases, methods and materials for determining if a mammal (e.g., a human) has a proteinopathy based, at least in part, in the presence or absence of misfolded polypeptides in a sample obtained from the mammal are provided.
