Abstract: A method for controlled production of an array of planar microparticles with the multiplexing of molecules on the surface thereof, intended to function as molecular sensors and/or actuators and a matrix (array) of microparticles, the surface thereof being printed with all of the molecular components required to provide the surface with functionality. Different molecular elements are multiplexed on the surface of each particle while they are supported on a substrate by means of a structural foot engraved below the particle. These microparticles can be released mechanically from the support on which they are produced using a controlled mechanical rupture method which is not chemically aggressive and therefore does not affect the molecules previously printed on the surface. The array and the particles contained therein offer great versatility in both chemical and/or biological applications.
