Abstract

The present disclosure is directed to microneedle patches for direct sampling and ultrasensitive detection of protein biomarkers in dermal interstitial fluids. The microneedle patches are comprised of polymers with high protein absorption capability (e.g. polystyrene) and are modified with capture biorecognition elements that are specific to target analytes in the interstitial fluid (ISF). Systems and methods are further provided for detection of a target ISF analyte obtained by in vivo sampling of the ISF using a microneedle patch.
