Аннотация:The influence of superficial relief onto the crystallization process of amino acid L-valine is studies. The substrates were monocrystalline silicon wafers modified photolitografically. The shapes of ordered elements of relief were left and right spirals with a radius of 5 μm and a height of about 1 μm. The crystallization of valine was realized in microdroplets deposited onto the silicon substrates from ultrasonic mist. The data obtained could be regarded as a base for elaboration of a new method for racemates separation that can be important for pharmacology and medicine.
