Abstract: A new device and methods that allow for improved sequestration and preservation of harvested analytes and biomolecules from biofluid samples is defined. The new device and methods relate to an improved dried biofluid collection substrate that is absorbent and contains a plurality of affinity ligands located within defined sample collection regions for enhanced analyte collection and storage. The device and methods allow for simple, safe and reliable ambient temperature collection and preservation of molecules captured from biological and environmental fluids in quantities suitable for analysis and diagnostic testing.
