Objective: The objective of this SGER proposal is to investigate extraordinary transmission effect in plasmonic crystals to develop fundamentally new detection platforms for quantitative, specific and high throughput detection of biomolecules. Intellectual Merit: Extraordinary transmission effect has been suggested for various applications ranging from sensing, to near-field optics and optoelectronics. But, its underlying physical mechanism is still not clear. In this proposal the PI will investigate the origin of the effect and focus on engineering new plasmonic crystal structures that can support both propagating and localized plasmons. In particular, the shape effect of the nano-apertures will be investigated both numerically and experimentally for strong field enhancement and large plasmon resonance shift. The structures will be tested by using various model biomolecules with different sizes to determine the metric of sensors. Surface chemistry will also be optimized for structured gold surfaces. Broader Impacts: The broad goal of this proposal is to integrate plasmonics and nanophotonics concepts for realization of new generation of biosensors. The PI will put strong effort to integrate research and education by feeding new research results back into the courses that PI is currently developing, trying to attract underrepresented minority students, and by working with outreach programs to help young students start a career in science and technology,. In particular, the PI will continue to organize hand-on activities for existing outreach programs of Boston University such as Upward Bound Math and Science and Summer Pathways that are targeting minority high school students.

目的：该SGER提案的目的是研究等离子体晶体中的非凡传输效应，以开发用于生物分子定量，特异性和高通量检测的全新检测平台。智力优势：在传感、近场光学和光电子学等领域，都有着非常重要的应用。但是，其潜在的物理机制仍然不清楚。在这项提案中，PI将研究这种效应的起源，并专注于设计新的等离子体晶体结构，以支持传播和局部等离子体。特别是，纳米孔径的形状效应将研究数值和实验强场增强和大的等离子体共振位移。这些结构将通过使用具有不同尺寸的各种模型生物分子来测试，以确定传感器的度量。还将针对结构化金表面优化表面化学。更广泛的影响：该提案的主要目标是整合等离子体和纳米光子学概念，以实现新一代生物传感器。PI将通过将新的研究成果反馈到PI目前正在开发的课程中，努力吸引代表性不足的少数民族学生，并通过与外展计划合作，帮助年轻学生开始科学和技术职业生涯，来大力整合研究和教育。 特别是，PI将继续为波士顿大学现有的外展计划组织实践活动，例如针对少数民族高中生的数学和科学向上训练以及夏季途径。
