In the methylene blue (MB)-phenylalanine (Phe)-tungsten( vi ) oxide (WO 3 ) colloid ternary aqueous solution, the MB H-aggregates, which could recognize the chirality of d - and l -Phe, were formed and investigated by means of UV-Vis absorption and CD spectroscopy. These results demonstrate a chirality transfer and amplification from only the pre-adsorbed Phe molecules to MB aggregates formed on the WO 3 colloid surface via non-covalent interactions. In the MB-Phe-WO 3 ternary aqueous solution, the MB H-aggregates, which could recognize the chirality of d - and l -Phe, were investigated.
