3-D Composite Metallodielectric Nanoresonant Array Fabrication With Enhanced Sensing Abilities

Technology Description

The subject invention details a new surface plasmon-based sensing chip for array-based detection sensors for environmental monitoring; explosive detection; protein-protein interaction for genomics, pharmaceuticals, proteomics, disease discovery, and drug development; and physical parameter detection and monitoring, such as temperature, pressure, and surface deposition thickness

Advantages

• Synergetic combination of two surface plasmonic resonances, propagating surface plasmon polariton (SPP) waves and localized surface plasmon resonant (LSPR) modes.
  
• Effective excitations and couplings of SPPs and LSPRs achieved by exciting SPPs, which propagate along the metallic surface, and couplings to LSPRs supported by the nanoresonant structures.
  
•  Nanoresonant structures are built over hole-array structures by depositing a controlled layer of metal at an oblique angle onto deeply perforated polymer film to realize controlled void diameter for excitation of LSPRs, while SPPs are excited by the periodic structure via the wave vector matching condition.
  
• Achievement of enhanced sensing applications in physical parameter and bio-recognition reactions.
