Abstract
The present disclosure relates to a sensor for indicating food quality comprising a semi-permeable film layer, the semi-permeable film layer comprising at least one integrally formed well having at least one sensing element disposed therein; wherein the well is sealed by a second film layer, the semi-permeable film layer being impermeable to said sensing element but is permeable to at least one analyte detectable by said sensing element.
Claims19
A sensor comprising a semi-permeable film layer, said semi-permeable film layer comprising at least one integrally formed well having at least one sensing element disposed therein;
- wherein the well is sealed by a second film layer, said semi-permeable film layer being impermeable to said sensing element but is permeable to at least one analyte detectable by said sensing element, wherein said semi-permeable film layer comprises at least two or more polyelectrolyte layers, and wherein oppositely charged polyelectrolyte layers are deposited alternately on each other.
A method of making a sensor, said method comprising the steps of:
- depositing a semi-permeable film coating on a patterned template to thereby form a semi-permeable film layer having at least one integrally formed well;
- disposing one or more sensing elements in said well;
- and
- encapsulating said sensing elements in said well;
- wherein said semi-permeable film layer is not permeable to said sensing element but is permeable to at least one analyte detectable by said sensing element, wherein said semi-permeable film layer comprises at least two or more polyelectrolyte layers, and wherein oppositely charged polyelectrolyte layers are deposited alternately on each other.
