WebThe structural basis of enantiomerism is called chirality. Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical. A pair of enantiomers is distinguished by the direction in which when dissolved ... WebImportantly, our chiral quasi-BICs are enabled by nonlocal surface lattice resonances, where the modes spatially extend into many adjacent meta-atoms. This nonlocal spatial extend feature is beneficial for applications of chiral drug analysis, biosensing, and quantum entanglement between remote emitters. 5 Experimental Section Simulations
