Provided herein are methods and kits for detecting the presence of DNA and/or RNA mutations associated with cancer (e.g., lung cancer). The methods and kits employ microcarriers, each with a probe specific for a DNA or RNA mutation and an identifier unique to the probe sequence. Upon isolation and amplification of nucleic acids from a sample, hybridization of amplified DNA with a probe, specific for a DNA or RNA mutation, that is coupled to a microcarrier indicates the presence of the mutation in the sample. Since each microcarrier can be identified through detection of the identifier, multiplex screening assays are provided. Representative genes that can be screened for mutations include, e.g., KRAS, NRAS, PIK3CA, BRAF, EGFR, AKT1, MEK1, and HER2 for DNA mutations and/or ALK, ROS, RET, NTRK1, and cMET for RNA mutations.

A method of forming a polymer matrix array includes treating a surface within a well of a well array with a surface compound including a surface reactive functional group and a radical-forming distal group; applying an aqueous solution including polymer precursors to the well of the well array; and activating the radical-forming distal group of the surface coupling compound with an initiator and atom transfer radical polymerization (ATRP) catalyst to initiate radical polymerization of the polymer precursors within the well of the well array to form the polymer matrix array.
