Abstract
A method for labeling an object such as a biological sample, including printing at least two different light-emitting species onto a substrate which are capable of displaying a unique optical signature when excited; and externally attaching the object to the printed at least two different light-emitting species. Also, a method for conducting a large scale test, including printing a first label onto a first substrate, the first label comprising at least two different light-emitting species capable of displaying a first unique optical signature when excited; printing a second label onto the first substrate or a second substrate, the second label comprising at least two different light-emitting species capable of displaying a second unique optical signature when excited; externally attaching a first object, such as a first biological sample to the first label; externally attaching a second object, such as a second biological sample to the second label; processing the first and second objects in a combined manner; analyzing the processed first and second objects; and identifying the analyzed first and second objects using their respective first and second labels.
