NER: Nanowire Spectrophotometer for Lab-on-a-Chip Chemical Analysis

这个项目将开发一种新型的纳米级设备，称为纳米线光谱仪，用于化学分析。这项工作将包括四个步骤：(1)合成和表征在紫外可见光区具有带隙的硫化镉、镉和硫化锌纳米线；(2)将单根纳米线和二维纳米线筏流体组装到绝缘体衬底上；(3)纳米线和纳米线筏内自对准间隙的制备和光学测试；以及(4)通过将纳米线光源和检测器与微流控相结合来制造光谱仪(单波长和多波长)。该项目的更广泛影响包括紧密结合的研究和教育计划。该项目的成功完成将引领低成本、便携式、微型光学光谱仪的发展，在环境监测、生物医学等许多领域具有潜在的应用前景。

0609083AgarwalThis project will develop a new type of nano-scale device called a nanowire spectrometer for chemical analysis. The work will involve four steps: (1) synthesis and characterization of CdS, CdSe and ZnS nanowires with energy band gaps in the UV-Visible region; (2) fluidic assembly of single nanowires and 2-D nanowire rafts onto insulator substrates; (3) fabrication and optical testing of self-aligned gaps within nanowires and nanowire rafts; and (4) fabrication of spectrometers (single and multiple wavelength) by integrating the nanowire light source and detector with microfluidics. The broader impacts of the project include closely coupled research and education plans. Successful completion of the project could lead the development of low-cost, portable, miniature optical spectrometers with potential applications in environmental monitoring, biomedicine and many other fields.
