Table 1. Enantioselective synthesis of MA by chiral-encoded mesoporous platinum.

Electrodes	Ratio of imprinted molecule*	% Enantiomeric excess†
(R)-MA imprinted	0.03	5.66
	0.05	10.71
(S)-MA imprinted	0.03	−11.73

^*Weight ratio of MA to H₂PtCl₆ in the electroplating mixture.

^†% Enantiomeric excess (% ee)=(RMA−SMA)/(RMA+SMA) × 100, where RMA and SMA are the HPLC peak areas of (R)-MA and (S)-MA, respectively. The calculated s.e.m. is ±1.13% ee (Supplementary equation (2)).
