Abstract:
1. A microfluidic device for detecting the presence of one or more analytes in a saliva sample, comprising: one or more pre-treatment chambers comprising a surface which comprises a first molecule capable of specifically or non-specifically binding to one or more saliva components in the saliva sample interfering with the detection of the one or more analytes for specifically or non-specifically removing at least a part of the fraction of components in the saliva sample interfering with detection of the one or more analytes, wherein the first molecule capable of specifically or non-specifically binding to one or more saliva components in the saliva sample interfering with detection of the one or more analytes is hydroxyapatite or an anti-mucin antibody; and a detection chamber separate from and fluidically coupled to the one or more pre-treatment chambers and comprising a biosensor surface, the biosensor surface comprising:
