研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
The laser-printed periodically-arranged nanovoid arrays offer a novel flexible multi-purpose sensing platform, useful for bioassay studies and various chemo- and bio-sensing applications. The FLPR of the nanovoid array is highly sensitive to both local and bulk RI changes of the superstrate, applicable for gas and SEIRA-based molecular sensing. Further optimization can extend the application range of the proposed SP sensors.
研究不足
The technical and application constraints include the need for further optimization to improve the detection limit of the sensing platforms, especially for lower gas concentrations. Potential areas for optimization involve fabrication of nanovoid arrays with their FLPR position <1 μm and optimization of the nanovoid geometry and chemical composition.
