Abstract
Competitive and sandwich-type immunodiagnostic assays can be configured by use of liposomes carrying detectible markers (e.g., fluorophores) or catalysts thereof (e.g., enzymes) on the outer liposome surface. The liposome also contains at least one antigen or antibody allowing it to bind to a complementary, immobilized antibody or antigen on a support.
