研究目的
To develop a large-scale, omnidirectional, and polarization-independent metamaterial-based chemical sensor (MCS) for detecting volatile organic solutions (VOS) with high sensitivity and figure-of-merit.
研究成果
The developed MCS demonstrates high sensitivity and figure-of-merit for VOS sensing, with potential applications in chemical sensors, biosensors, food safety, and live cell monitoring. The fabrication method is simple, cost-effective, and scalable for mass production.
研究不足
The study focuses on the UV-visible wavelength range and may not cover other spectra. The sensitivity and figure-of-merit, while high, may have room for improvement for certain applications.
1：Experimental Design and Method Selection:
The study involves the fabrication of a metamaterial-based chemical sensor (MCS) using hybrid nanopillars through direct metal deposition and post thermal annealing treatment. The EM field modulation between nanopillars is utilized for sensing.
2：Sample Selection and Data Sources:
The MCS is tested with various volatile organic solutions (VOS) to investigate its sensing capabilities, focusing on refractive index changes.
3：List of Experimental Equipment and Materials:
Includes hybrid Au/SiO2/Si nanopillars, PDMS-based microfluidic channels, and various VOS for testing.
4：Experimental Procedures and Operational Workflow:
The MCS is encapsulated in a PDMS-based microfluidic channel, filled with different VOS to compare their refractive indexes and investigate the sensitivities of MCS.
5：Data Analysis Methods:
The reflective spectra of MCS under different conditions are analyzed to determine sensitivity and figure-of-merit.
