Consolidating Molecular Logic with New Solid-Bound YES and PASS1 Gates and Their Combinations

Proton-driven YES and PASS1 molecular logic tags based on anthracene and 4-aminonaphthalimide fluorophores, emitting blue and green, respectively, are employed on amino-terminated polyethylene glycol-polystyrene and aminopropyl silica particles. The (YES+PASS1) logic combination is also a distinguishable tag in both colours. The scope of such tags is delineated.
