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。该工作将包括四个步骤：(1)在紫外可见区具有能带隙的CdS、CdSe和ZnS纳米线的合成和表征；(2)单纳米线和二维纳米线筏在绝缘体衬底上的流体组装；(3)纳米线和纳米线筏自对准间隙的制备与光学测试；(4)将纳米线光源和探测器与微流体相结合，制成单波长和多波长光谱仪。该项目更广泛的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、微型光谱仪的发展，在环境监测、生物医学和许多其他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.
