Unconventional nanoporous antenna-like heterostructure arrays, inspired by insect tentacles, are developed for efficient interfacial sensing of biomolecules and cellular activities. The obtained nanoporous cubes (head segments) serve as a robust substrate for site-selective cell adhesion and culture, allowing for sensitive detection of biomolecules. Meanwhile, the single-crystalline nanowires (arm segment) provide efficient charge transport toward the electrode substrate. The inspired hetero-biointerfaces exhibit substantial enhanced electrocatalytic activity and sensitivity for biomolecules.
