Gap plasmon resonators are the smallest optical cavities currently feasible. They are fabricated using metallic nanocubes which are coupled to a metallic surface. The cross section of this kind of resonators is very large, which is an important advantage in the context of molecules sensing. These structures are actually very sensitive to their close optical environment and can thus be used to build optical molecule sensors which could be used in the context of Point-of-Care testing. The physics of these objects is complex and the diversity of their optical response is large. We plan to explore this physics thoroughly and then to develop a new method to assemble theses structures. This method should allow to produce sensors that would be simple, efficient and low cost, so that they could be used as close as possible to patients for a quick diagnosis.
