Method for production of moulded bodies, in particular optical structures and use thereof
First Claim
1. A method for manufacturing an evanescent-field measuring platform including a first layer and a second layer, said second layer being made of an essentially optically transparent thermoplastic plastic comprising manufacturing of said second layer using a master,wherein said master is a glass master having a surface coated with metal oxide,wherein said manufacturing of said second layer includes directly molding said thermoplastic plastic using said master as part of a molding tool, without deposition of further coatings on said coated surface of said master prior to said directly molding.

Abstract
The present invention relates to a method for manufacture a body from a thermoplastic plastic with a three-dimensionally structured surface, wherein molding is performed directly from a master made of glass coated with metal oxide, without deposition of further coatings on a surface of the master. The invention also relates to bodies manufactured with this method from a thermoplastic featuring a three-dimensionally structured surface, as well as to planar optical structures likewise manufactured with this method for generating evanescent-field measuring platforms and to a use thereof. The invention furthermore relates to a planar optical structure for generating an evanescent-field measuring platform, comprising a first essentially optical transparent, waveguiding layer (a) with refractive index n1 and a second essentially optical transparent layer (b) with refractive index n2, where n1>n2, in a case of an embodiment of a planar optical film waveguide, or comprising a metal layer (a′) and a second layer (b), in a case of an embodiment for generating a surface plasmon resonance, wherein the second layer (b) comprises a material from a group comprising cyclo-olefin polymers and cyclo-olefin copolymers.
