    • A method for the transformation of material (e.g. plastic material) into an optically modulating state via laser radiation is described. The optically modulating state may be a state in which light is emitted at a different wavelength than it is absorbed. The plastic material to may be a thermoplastic or elastomeric material, or an organic polymer selected from the group consisting of polyethylene, polypropylene, polystyrene, polycarbonate and polycycloolefin. The laser radiation may comprise the application of an amount of energy of about 0.1 nJoule/μm 2 to about 100 μJoule/μm 2 and/or may comprise a radiation of a wavelength of about 355 nm to about 1064 nm. The optically modulating state of the plastic material may absorb light in a wavelength spectrum of about 380 nm to about 540 nm and/or a wavelength spectrum of about 635 nm to about 655 nm. The optically modulating state of the plastic material may emit light in a wavelength spectrum of about 550 nm to about 800 nm. The transformation of the plastic material may comprise the generation of optically modulating elements on the surface of said plastic material, selected from the group comprising geometrical forms, geometrical pattern, spots, dots, lines, circles, squares, characters, symbols, drawings, barcode and datamatrixcode. The material may be used as component for the manufacture of a device, microfluidic device, system, cartridge or instrument. Based on the employment of the material the usability of a device or system and/or of any procedure, function or method carried out with it or in it may be determined and/or controlled.
