Abstract: The present invention provides a computer-implemented method for analysing cell culture image data, in particular for analysing the spatiotemporal behaviour of the occurrence of a cellular event in a cell culture. The method comprise obtaining image data comprising a set of images of the cell culture at a plurality of consecutive time points, using an image analysis algorithm to determine the position of cells in at least a first population of cells in each of the images, linking at least some of the positions of cells in the images into respective cell tracks, and identifying the timing and position of occurrence of a cellular event in each of a plurality of cell tracks. The method may also comprise obtaining a spatiotemporal map of the events that have been identified, and quantifying the spatiotemporal pattern of occurrence of the event.

Abstract: A sensor comprises a plurality of sensor elements arranged in an array. Each sensor element is memristive and has an electrical resistance characteristic related to exposure to a species to be sensed. The sensor elements are arranged to be connectable such that at least one sensor element is connected in parallel with at least one other sensor element. By using appropriate connections, the array of sensor elements can be read.
