Abstract: Detection of a low quantity of volatile molecules in the air is an important task from safety regulation to discovery of unknown bio-pathways which involve active volatile molecules. We suggest grow in a single-step hierarchically organized silver macrocrystals. We expect to detect a very small amount of molecules in the air due to its self-organization with increased SERS activity. To grow the crystal, we used spring geometry copper precursors resulting in geometry guided organization of silver 3D dendritic porous crystals. We tested our crystals for SERS detection of benzenethiol obtaining a high SERS signal from spicules of the macrocrystal.
