A microstructure has at least one bonding substrate and a reactive multilayer system. The reactive multilayer system has at least one surface layer of the bonding substrate with vertically oriented nanostructures spaced apart from one another. Regions between the nanostructures are filled with at least one material constituting a reaction partner with respect to the material of the nanostructures. A method for producing at least one bonding substrate and a reactive multilayer system, includes, for forming the reactive multilayer system, at least one surface layer of the bonding substrate is patterned or deposited in patterned fashion with the formation of vertically oriented nanostructures spaced apart from one another, and regions between the nanostructures are filled with at least one material constituting a reaction partner with respect to the material of the nanostructures. A microsystem is formed from two bonding substrates and a construction lying between the bonding substrates, the construction having a reacted reactive layer system. The microsystem is a sensor coated with biomaterial and/or has elements composed of polymeric material and/or at least one magnetic and/or piezoelectric and/or piezoresistive component.
