Abstract
A detection device for detecting a marker in a liquid, comprising a reaction chamber, provided with a thermosensitive sensor, wherein said reaction chamber comprises an photopolymer capable of releasing or generating a chemical species that is capable of undergoing or initiating an exothermic or endothermic chemical reaction with a marker present in the liquid.
Claims21
A detection device for detecting a marker in a liquid, comprising:
- a reaction chamber;
- a thermosensitive sensor placed in the reaction chamber;
- and
- a photopolymer layer capable of releasing or generating a chemical species that is capable of undergoing or initiating an exothermic or endothermic chemical reaction with a marker present in the liquid, wherein the photopolymer layer is deposited on the walls and/or on the floor of the reaction chamber and/or on the thermosensitive sensor,
- wherein the photopolymer layer is obtainable by a method comprising the following steps:
- a step of depositing a layer of a photocurable epoxy composition exhibiting an excess of photoinitiator on the walls and/or on the floor of the reaction chamber and/or on the thermosensitive sensor itself;
- a step of photocuring with UV radiation the layer of the photocurable epoxy composition exhibiting an excess of photoinitiator, so that exceeding unreacted acid molecules are left adsorbed in the bulk and/or on the surface of an acidified photopolymer layer.
