Gas and odor sensing plays pivotal roles in energy industry, healthcare, food safety, security, defense, and environmental protection, but it still remains a grand challenge given the stringent requirement of sensitivity and selectivity. So why not learning from our noses that have been perfected by millions of years of evolution. The mammalian olfactory system is well recognized for its ability to identify a large number of airborne molecules, far better than most artificial sensors. The objective of this project is to develop a bio-inspired photonic nose (P-nose) system by mimicking the mammalian olfactory system, which will enable ultra-compact optical gas and odor sensing technology with ultra-high sensitivity and specificity. This research will point out a unique way to advance the frontline research of bio-inspired systems and transcend existing bench-top optical gas sensing technology into system-on-chip level for a broad spectrum of engineering applications. The synergy of this research and education will benefit graduate and undergraduate students at the Oregon State University by enhancing the curricula of nanophotonic technology, broaden the participation of under-represented minorities through leveraging the summer research programs of the Student Chapter of the Optical Society of America at OSU, and use a multidisciplinary approach to educate and develop future high-tech entrepreneurs in technology-based ventures. The objective of this project is to investigate a bio-inspired photonic nose system by mimicking the mammalian olfactory system, which will enable system-on-chip optical gas and odor sensing technology with ultra-high sensitivity and specificity. The mammalian olfactory system is well recognized for its ability to identify a large number of airborne molecules, far better than most artificial sensors. The ultra-high sensitivity and specificity of the mammalian olfactory system come from two critical mechanisms: 1) the mucous membrane inside the nasal cavity with large surface areas (70cm2) to capture trace level of gas and odorant molecules; and 2) a combinatorial response of about four hundred different olfactory receptor neurons to sense more than ten thousand types of odorant. The proposed biomimetic P-nose system will integrate the PIs' recent research breakthroughs in both nanomaterials and photonic devices: 1) nanoporous metal-organic framework materials as highly efficient and selective gas and odorant absorbents mimicking the mucous membrane inside the nasal cavity; and 2) narrow-band plasmonic filter array with ultra-high detection sensitivity that is analogue to olfactory receptor neurons to probe the finger-print infrared absorption spectra of various gas and odorant molecules. A fully system-on-chip optical gas and odor sensing technology will be demonstrated at the end of this project to simultaneously detect multiplex gases including CO2, CH4, and volatile organic compounds at the near-infrared wavelength range.Intellectual Significance: Ultra-compact gas and odor sensors play pivotal roles in many engineering applications. State-of-the-art technology is dominant by electronic nose that relies on arrayed electronic gas sensors made of metal-oxides and conductive polymers, which lack sensitivity and specificity. Compared with exiting E-nose techniques, the proposed biomimetic photonic nose probes the finger-print IR spectra and is expected to bring transformative impact in detection sensitivity, specificity, sensing time, power consumption, as well as the capability to work under extreme conditions such as in explosive gas atmosphere, radiation, or high electric/magnetic fields. Such bio-inspired concept of photonic nose can be ultimately implemented by integrating chip-scale nanophotonic devices with emerging nano-porous materials, and will open a new path toward system-on-chip optical gas sensing with full functionalities including gas capture, sensing, spectroscopy, and pattern recognition.

气体和气味传感在能源工业、医疗保健、食品安全、安保、国防和环境保护中发挥着关键作用，但鉴于对灵敏度和选择性的严格要求，它仍然是一个巨大的挑战。那么为什么不向我们经过数百万年进化而完善的鼻子学习呢？哺乳动物的嗅觉系统因其识别大量空气分子的能力而受到广泛认可，远远优于大多数人工传感器。该项目的目标是通过模仿哺乳动物的嗅觉系统来开发仿生光子鼻（P-nose）系统，这将使超紧凑的光学气体和气味传感技术具有超高的灵敏度和特异性。这项研究将指出一种独特的方法来推进仿生系统的前沿研究，并将现有的台式光学气体传感技术提升到片上系统级别，以实现广泛的工程应用。这项研究和教育的协同作用将通过加强纳米光子技术课程，使俄勒冈州立大学的研究生和本科生受益，通过利用俄勒冈州立大学美国光学学会学生分会的夏季研究项目，扩大代表性不足的少数群体的参与，并采用多学科方法教育和培养技术型企业中的未来高科技企业家。该项目的目标是通过模仿哺乳动物嗅觉系统来研究仿生光子鼻系统，这将使片上系统光学气体和气味传感技术具有超高灵敏度和特异性。哺乳动物的嗅觉系统因其识别大量空气分子的能力而受到广泛认可，远远优于大多数人工传感器。哺乳动物嗅觉系统的超高灵敏度和特异性来自两个关键机制：1）鼻腔内的粘膜具有大表面积（70cm2），可以捕获微量的气体和气味分子； 2）大约四百个不同的嗅觉受体神经元的组合反应，以感知一万种以上的气味。所提出的仿生P-nose系统将整合PIs最近在纳米材料和光子器件方面的研究突破：1）纳米多孔金属有机框架材料作为高效、选择性的气体和气味吸收剂，模仿鼻腔内的粘膜； 2）具有超高检测灵敏度的窄带等离子体滤光片阵列，类似于嗅觉受体神经元，可探测各种气体和气味分子的指纹红外吸收光谱。该项目结束时将展示一种完整的片上系统光学气体和气味传感技术，可在近红外波长范围内同时检测多种气体，包括 CO2、CH4 和挥发性有机化合物。 智力意义：超紧凑型气体和气味传感器在许多工程应用中发挥着关键作用。最先进的技术以电子鼻为主，它依赖于由金属氧化物和导电聚合物制成的阵列电子气体传感器，缺乏灵敏度和特异性。与现有的电子鼻技术相比，所提出的仿生光子鼻探测指纹红外光谱，预计将在检测灵敏度、特异性、传感时间、功耗以及在爆炸性气体环境、辐射或高电磁场等极端条件下工作的能力带来变革性影响。这种受生物启发的光子鼻概念最终可以通过将芯片级纳米光子器件与新兴纳米多孔材料集成来实现，并将为具有气体捕获、传感、光谱和模式识别等全功能的片上系统光学气体传感开辟新的道路。
