1. A high-input detector module for classifying a cell status based on detecting whether an input microRNA is expressed at a specific level or higher than a reference level, wherein said high-input detector module comprises: (a) a constitutive or inducible promoter sequence operably linked to: (i) a repressor sequence encoding a repressor product and (ii) a sequence encoding one or more microRNA target sequences, wherein said sequence encoding one or more microRNA target sequences is the target sequence of the one or more input microRNAs the module is designed to detect; and (b) a repressible promoter sequence operably linked to an output sequence encoding an ouput product, wherein said repressor product is specific for the repressible promoter sequence.
