Abstract: There is provided a protein-halide perovskite nanocrystal (p-HPNC) comprising: a crystalline core of halide perovskites and an outer layer made of protein surrounding the crystalline core. The protein has a net positive electric charge at a pH of 3 or less in its free state. The protein is linked to the surface of the crystalline core, and the halide perovskites have a formula ABX3, where A is a monovalent cation, B is a divalent cation, and X is a monovalent halide anion.

Abstract: There is provided a microfluidic chip for sensing an analyte in a sample by colorimetry. The microfluidic chip comprises: an inlet adapted to receive the sample; an incubation chamber having an incubation chamber inlet fluidly connected to the inlet downstream thereof, to incubate the analyte in the sample; a filter barrier fluidly connected to the incubation chamber, downstream of the incubation chamber inlet; a sensing chamber fluidly connected to the incubation chamber, downstream of the filter barrier, the sensing chamber having a plasmonic nanosurface, the plasmonic nanosurface including nanostructures protruding from the plasmonic nanosurface, the nanostructures having a size that is smaller than that of the diffraction limit of light, the nanostructures having a metallic layer that is plasmon-supported on top of a back reflector layer; and an outlet fluidly connected to the sensing chamber downstream thereof.

Abstract: It is provided a biosensor, a device containing same and method for detecting a target protein, the biosensor comprising a nano/micro islands (NMIs) core of gold spatially oriented with nanorough protrusions, and a layer of electropolymerized molecularly imprinted polymers (MIP) polymerized on the NMIs core, said MIP consisting of a conductive monomer comprising a built-in recognition site of the target protein, wherein the MIPs generate an electrical signal upon binding of the target protein.

Abstract: There is described herein methods and devices for confining and/or manipulating molecules. At least one molecule is introduced into a fluidic chamber. The fluidic chamber is formed inside a device comprising at least one first electrode having a first surface spaced from at least one second electrode having a second surface facing the first surface. The at least one second electrode has a plurality of dielectric structures arranged to form openings along the second surface. At least one electrical signal is applied across the at least one first electrode and the at least one second electrode to generate a non-uniform electric field having electric field lines extending from the first surface of the at least one first electrode to the second surface of the at least one second electrode in the openings formed between the dielectric structures. The at least one electrical signal has a frequency level causing the at least one molecule to move inside the fluidic chamber in accordance with a predetermined movement.
