Abstract:
1. A method of detecting biological analytes comprising: suspending a target analyte in a suspending solution containing polymeric particles with an attached probe, wherein said probe has specific affinity for said target analyte; adding at least one recognition unit-peroxidase conjugate marker to said suspending solution, wherein said recognition unit associates with said target analyte; forming a complex of said target analyte, said polymeric particles with an attached probe, said recognition unit-peroxidase conjugate marker; contacting a gelatin surface with said suspending solution; adding developer to said suspending solution in contact with said gelatin surface in the presence of phenol to attach said complex to said gelatin surface; washing said gelatin surface; and detecting said complex attached to said gelatin surface.
