    Abstract: A process for producing microfluidic articles comprises (a) preparing a photoreactive composition comprising (1) at least one reactive species that is a polymer or a polymer precursor and that is capable of undergoing an acid- or radical-initiated chemical reaction and (2) at least one multiphoton photoinitiator system; (b) exposing a portion of the composition to light sufficient to cause simultaneous absorption of at least two photons, thereby forming exposed and unexposed portions of the composition, and thereby inducing at least one acid- or radical-initiated chemical reaction in the exposed portion; and (c) removing either the exposed or the unexposed portion of the composition, so as to form a microfluidic article comprising a seamless polymer matrix that defines at least one inlet, at least one outlet, and a microfluid processing architecture that is capable of fluidic communication with the inlet and the outlet and that is otherwise fully enclosed within the polymer matrix.

    Abstract: Disclosed herein is a microstructured tool having a microstructured layer having a polymer and a microstructured surface; a nickel layer disposed adjacent the microstructured layer opposite the microstructured surface; and a base layer disposed adjacent the nickel layer opposite the microstructured layer. The microstructured surface may have at least one feature having a maximum depth of up to about 1000 um. Also disclosed herein is a method of making the microstructured tool using laser ablation. The microstructured tool may be used to make articles suitable for use in optical applications.

    Abstract: A composite article having large scale predictable dimensional stability comprises a metal foil backing having adhered thereto a layer of cured polymer having an exposed surface bearing a three-dimensional microstructure of precisely shaped and located functional discontinuities. The article is made by depositing a layer of a radiation curable composition onto a metal foil backing, contacting a master with a pattern capable of imparting a three-dimensional microstructure of precisely shaped and located functional discontinuities into the layer of radiation curable composition, while the layer of radiation curable composition is in contact with the master, exposing the curable composition to radiation to cure the composition, and separating the cured polymer layer on the metal foil backing from the surface of the master. Either the metal foil backing or the master may be radiation transmissive.
