This cover image illustrates a waveguide-integrated surface-enhanced nanoantenna chip that simultaneously measures the amide I and II band absorption of proteins. When a long-wave infrared light is launched, an evanescent field is formed on the surface of the waveguide. The absorption of protein molecules is further enhanced with a high-intensity field excited by the gold nanoantenna. The idea of integrating the large-core rib silicon waveguide and gradient nanoantenna array can be used for multiplexed broadband biomolecular absorption detection with high-throughput. See article 2400871 by Xia Yu and co-workers for more details.
