LATERAL FLOW IMMUNOASSAY TECHNIQUE

A technique for performing an immunoassay of analytes (102) in a sample (104) is described. As to a device aspect of the technique, the device (100) comprises a membrane (106) including a first site (108), a second site (110) laterally separated from the first site and multiple spots (112) arranged...

Zusammenfassung:	A technique for performing an immunoassay of analytes (102) in a sample (104) is described. As to a device aspect of the technique, the device (100) comprises a membrane (106) including a first site (108), a second site (110) laterally separated from the first site and multiple spots (112) arranged between the first site (108) and the second site (110), each spot (112) including binding molecules for selectively binding the analytes (102) at the corresponding spot (112); a liquid phase (114) configured to carry the sample (104) and labels (116) for optically signaling the presence of the analytes (102), and to laterally flow (118) from the first site (108) across the spots (112) to the second site (110); and an image acquisition unit (128) configured to acquire a sequence of images, wherein each image captures the multiple spots (112), and the sequence of images is indicative of optical signals from the labels (116) at different points in time during the lateral flow (118).
