A novel electrochemiluminescence (ECL) luminophor of amoxicillin was studied and found to generate ECL following the oxidation or reduction of amoxicillin. The amoxicillin oxidation state was also found to eliminate the reduction state, generating ECL. When solutions of amoxicillin were scanned between þ1.5 V and 1.0 V with a graphite electrode in the presence of cetyltrimethyl ammonium brom…
