#Chiral (left/right-handed) molecules are crucial to biochemistry. Light can distinguish between them but interacts too weakly, and boosting with #nanophotonics is not easy because it destroys chirality of EM fields. Typical solution is to design #nanostructures with highly chiral field that makes molecules absorb circularly polarised light differently. Here we find a much stronger effect where the molecules make nanostructures absorb light differently!

#Chirality of #BioMolecules (left/right-handedness) is central to life. Light can be chiral too, a tool to interact with them. Light can also excite spins in #2dSemiconductors and rotate objects. #Nanophotonics can enhance these very weak effects. We surprisingly found that different phenomena, all relying on chirality of light, are incompatible! And found design rules for #metasurfaces for enhancing different chiral interactions (led by @albertogcurto).

Scientists use #nanophotonics to improve light emission. The strong electric field near nanostructures can excite molecules and extract light from them more efficiently, creating better light sources. We usually model this by assuming that the emitter stays fixed. But in many practical materials, emitting #excitons move around! We found a recipe for making such devices better by figuring out how to do calculations more correctly (led by @albertogcurto): https://onlinelibrary.wiley.com/doi/10.1002/adom.202200103
