摘要： A light-emitting composition containing first and second light-emitting markers. The first light-emitting marker comprises a first light-emitting material and a first binding group configured to bind to a first target analyte. The second light-emitting marker comprises a second light-emitting material which is different from the first light-emitting material and a second binding group which is different from the first binding group and which is configured to bind to a second target analyte. A luminescent lifetime of the first light-emitting material is shorter than a luminescent lifetime of the second light-emitting material. The difference in lifetimes of the first and second light-emitting materials may be used to distinguish between the first and second target analytes in a sample, e.g. by time-gated flow cytometry.

摘要： A polymer comprising a repeating structure of formula (I): -D-X1-A-X2-. D is a conjugated electron-donating group of formula (II); A is a conjugated electron-accepting group; X1 and X2 are each independently a conjugated bridge group selected from phenylene, thiophene, furan, thienothiophene, furofuran, thienofuran, thiazole, oxazole, alkene, alkyne and imine, each of which may be unsubstituted or substituted with one or more substituents. The polymer has a highest occupied molecular orbital (HOMO) level as measured by square wave voltammetry of no more than 5.30 eV from vacuum level. The polymer may be used as an electron donor in an organic photodetector.

摘要： An apparatus for determining a presence, a concentration or a change in concentration of a target material in an environment is disclosed. The apparatus comprises first and second sensors configured to respond to the target material. The apparatus further comprises a fluid inlet in fluid communication with the environment, and a valve assembly having a first and second configuration. In the first configuration, the fluid inlet is in fluid communication with only the first sensor. In the second configuration, the fluid inlet is in fluid communication with the first sensor and the second sensor.

摘要： A target analyte in a sample may be identified using a light-emitting ting 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 dependently a substituent.
