文摘
Patterned glycine crystals nucleated on functionalized metallic square islands. This approach can be used to fabricate particles with micron dimensions and screen solid forms under different conditions. The size of the glycine crystals is controlled by the dimensions of the islands. High energy metastable 
-glycine crystallizes on small metallic islands, whereas for large islands, the polymorphic outcome becomes biased toward the 
-form.
