Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
Their discovery has recently been published in the journal Nature (« Photonic topological insulator induced by a dislocation in three dimensions »).
Nanogels are extremely versatile and hydrophilic materials that have a wide range of potential applications within the medical field. Research in this area has found that nanogels are particularly useful as therapeutic drug carriers and can also enhance medical diagnostics when used as carriers for novel imaging probes and contrast agents.Lire la suite
