摘要:
A biosensor includes a substrate with a layer of receptive material disposed thereon overlying a layer containing a photo-reactive agent. The receptive material is specific for an analyte of interest. A pattern of active and inactive areas of the receptive material are defined in the receptive material layer by a masking process wherein the photo-reactive agent is activated in the exposed regions of the mask.

The premature rupture of amniotic fluid (PROM) may be discovered through a number of inventive means. Methods of evaluating whether PROM is present include; a) through the testing of the pH of vaginal fluids using an irreversible pH test; b) through the detection of analytes (e.g. enzymes) specific to amniotic fluid in the vaginal fluids; c) though the detection of hydrogen peroxide (H2O2) in the vaginal fluid; and d) through the detection of cholesterol in vaginal fluid. While individually indicative of PROM, it is desirable to combine at least two of these techniques to yield a powerful tool of even greater reliability. Test devices and feminine hygiene pads into which the test methods may be incorporated are also included herein.

摘要:
A biosensor includes a substrate member with a pattern of active areas of receptive material and a pattern of blocking material layers. The receptive material and blocking material are attached to the substrate member with a photo-reactive crosslinking agent activated in a masking process. The receptive material is specific for an analyte of interest.

A biosensor includes a substrate with a receptive material layer of radiation-absorbing member (RAM)-tagged biomolecules disposed thereon. The receptive material is specific for an analyte of interest. A pattern of active and deactivated areas of the receptive material are defined in the receptive material layer by a masking process wherein areas are exposed through a mask with a light source to induce deactivation.
