In the continuous pursuit of enhancing the sensitivity of nanophotonic biosensors by leveraging phase phenomena,a recent development involved the engineering of an atomically thin Ge2Sb2Te5 layer on a silver nanofilm to generate large Goos-Hänchen-shifts associated with phase singularities.The resulting detection limit reached～7× 10-7 RIU.
