Molecular recognition, which is key to the correct functioning of most biological processes, is based on chiral entities fitting into and onto each other. Consequently, the concept of chirality appears virtually everywhere in biology and biochemistry. One striking optical manifestation of the chirality of biomolecules is circular dichroism (CD), which is very typical for biorelated systems. It has been demonstrated over the past decade that bioassembled plasmonic nanostructures offer amazing possibilities regarding chirality and optical responses, and the active research field of chiral bioplasmonics has recently generated a variety of new sensing platforms. In both molecular and nanoscale systems, optical manifestations of chirality arise from complex interactions between nonchiral elements. Such interactions decay rapidly with the distance between the elements, and therefore, a system with strong optical chiral responses typically is tightly packed. Here we show how to transfer chiral interactions effic...
