Abstract: A conjugated light-emitting polymer comprising a host repeat unit and an intermediate repeat unit in a backbone of the conjugated light emitting polymer, and an emissive unit. The host repeat unit has a wider band gap than the intermediate unit. The intermediate repeat unit has a wider band gap than the emissive unit. The emissive unit is either: an emissive repeat unit of a block copolymer wherein the block copolymer comprises a first block comprising the intermediate repeat unit and the emissive repeat unit and a second block comprising the host repeat unit; a substituent of a proportion of the host repeat units and at least some of the host repeat units substituted with an emissive unit are arranged directly adjacent to an intermediate repeat unit; a substituent of a proportion of the intermediate repeat units; or a repeat unit in the backbone of the conjugated polymer and is arranged directly adjacent to the intermediate repeat unit. The conjugated light-emitting polymer may be part of a light-emitting marker for detecting the presence of a target analyte in a sample.

Abstract: A target analyte in a sample may be identified using a light-emitting marker configured to bind to the target analyte. The sample containing the light-emitting marker is irradiated and emission from the sample at an emission wavelength of the light-emitting marker is detected. The method may be flow cytometry. The light-emitting marker comprises a light-emitting polymer comprising an electron-accepting repeat unit of formula (I) and an electron-donating repeat unit: (I) R1 and R2 independently in each occurrence is H or a substituent and X in each occurrence is independently a substituent. The light-emitting marker may be a particulate light-emitting marker comprising particles containing the light-emitting polymer and a matrix material, e.g. silica.

Abstract: A double layered, flexible thermoelectric generator with direct bonded, double layers of active materials that are directly bonded by heat curing, not soldered nor attached/bonded by an adhesive layer. The thermoelectric device is made from a first substrate and a second substrate, each including an n-type and p-type thermoelectric legs. The first and the second substrate are brought together so that the n-type and p-type thermoelectric legs of the first substrate come into direct contact with, respectively, the n-type and the p-type thermoelectric legs of the second substrate. Each thermoelectric leg may be disposed in a well formed in an insulating layer disposed over contact electrodes supported on the first and second substrate. Each thermoelectric leg may contain a particulate semiconductor and a binder, e.g. a polymer binder. The pairs of legs are bonded together by heat curing.
