Abstract
The invention is directed to enzyme immobilization compositions comprising: one or more enzymes, a humectant, an acrylic-based monomer, a water-soluble organic photo-initiator and a water-soluble acrylic-based cross-linker in a substantially homogeneous aqueous mixture. The invention is also directed to methods for forming sensors comprising such compositions and to apparati for forming arrays of immobilized layers on an array of sensors by dispensing such compositions onto a substrate.
Claims5
A sensor, comprising an electrode with a first layer covering said electrode comprising an ion-selective membrane, and a second layer covering said ion-selective membrane comprising a UV cured matrix formed from a homogeneous aqueous mixture of one or more enzymes, a humectant, an acrylic-based monomer, a water-soluble organic photo-initiator and a water-soluble acrylic-based cross-linker.
