Abstract
The invention relates to a sensing device for sensing target elements in a fluid. The sensing device comprises a substrate (61) having first regions (66a) and second regions (66b). A patterned first layer (62) is provided on the substrate (61), wherein the patterned first layer (62) covers the second regions (66b) and does not cover the first regions (66a). In the first regions (66a) capture elements (64) are arranged for capturing the target elements. Such a sensing device allows defining the first regions, i.e. capture regions, by the patterned first layer.
Claims12
Sensing device being usable for detecting target elements in a fluid, comprising:
- a substrate (61) having first regions (66a) and second regions (66b);
- a patterned first layer (62) on the substrate (61) covering the second regions (66b) such that the first regions (66a) are not covered by the first layer (62);
- and
- capture elements (64) arranged in the first regions (66a) for capturing the target elements.
A target element detection apparatus for detecting target elements in a fluid (3), wherein the target element detection apparatus (38) is adapted to be cooperable with a sensing device (1), wherein the sensing device (1) comprises:
- a substrate (61) having first regions (66a) and second regions (66b),
- a patterned first layer (62) on the substrate (61) covering the second regions (66b) such that the first regions (66a) are not covered by the first layer (62), and
- capture elements (64) arranged in the first regions (66a) for capturing the target elements,
- wherein the target element detection apparatus (38) is adapted to detect the target elements in the fluid, if they are captured by the capture elements (64) arranged in the first regions (66a).
Method for manufacturing a sensing device being usable for detecting target elements in a fluid, comprising the steps of:
- providing a substrate (61);
- providing a first layer (62) on the substrate (61);
- patterning the first layer (62) obtaining first regions (66a) and second regions (66b), wherein the second regions (66b) are covered by the patterned first layer (62) and the first regions (6a) are not covered by the patterned first layer (62);
- and
- providing capture elements (64) for capturing the target elements of the fluid in the first regions (66a).
