A monomolecular layer of first biological particles is adsorbed on the surface of a substrate fabricated of virtually any nonreactive solid material, the coated substrate is then exposed to a solution suspected of containing second biological particles specific to the first biological particles, next a porous, opaque layer of nonreactive third particles is formed in the coated substrate, and then the coated substrate is exposed to a cleaving agent solution which cleaves the bond between the first and second biological particles. A visual examination of the coated substrate surface clearly indicates to the naked eye or examination by suitable instrument whether the suspect solution contains the second biological particles by determining whether the opaque layer is complete or a portion common to the second biological particles, has been removed. |
