A Multiplex Chemotyping Microarray (MCM) system and methods are herein described. The MCM system and methods enable rapid chemical analyses of heterogeneous mixtures, by combining high-throughput micro-contact printing technology with high-fidelity (mass) vibrational spectroscopy. The MCM enables an error-free deposition and detection of multiple chemicals in a heterogeneous liquid sample at a throughput of more than two orders of magnitude beyond existing methods.
