The synthesis and initial evaluation of novel chromogenic substrates with potential in the detection and differentiation of cultured bacterial colonies are described. The substrates were readily hydrolysed by specific aminopeptidase activity to release the chromogen9-(4 '-aminophenyl)-10-methylacridinium salt which provided a clear visual indication of the presence of the corresponding bacteria.

Graphene/acridine (G-Acr) hybrid structures were synthesized through covalent functionalization of graphene oxide with 9-(4-aminophenyl)acridine (APA) and its derivatives. The G-Acr hybrids were characterized by Fourier transform infrared spectroscopy, ultraviolet visible spectrophotometry, thermal gravimetric analysis and Raman spectroscopy. X-ray photoelectron spectroscopy confirms that the binding energies of APA and its derivatives shifted to higher values, revealing pronounced charge transfer at the interface of graphene and organic molecules.

The amides 8a-e and 10a-c were prepared as chromogenicaminopeptidasesubstrates. A range of microorganisms were grown in the presence of these compounds and coloured colonies were produced in several cases after addition of acetic acid-thus giving potential methods for the detection of aminopeptidaseactivity and for microorganism identification.
