Research output: Patent


A system, device and/or method for multiplex assays are provided. In a particular, but non-limiting, example there is provided a multiplex array, such as a suspension array. Luminescence decay lifetimes are utilized for probes in a suspension array, and coding/decoding the codes from time-resolved spectra. Lifetime populations can be generated at distinct color bands. A novel temporal technique or dimension is applied over conventional spectral and intensity combinations, thereby expanding the multiplexing capacity of a suspension array. In one example form, the multiplexing capacity of a suspension array can be expanded to the order of about 58. This provides a reliable, high-throughput and relatively inexpensive solution for multiplex assays in various areas of application such as life sciences, data storage and security.
