Near-Infrared Fluorescent Nanomaterials for Detection of Trace Analytes

“这项奖励是根据2009年美国复苏和再投资法案（公法111-5）资助的。”化学系分析与表面化学（ASC）项目将资助美国北达科他大学赵晓军教授的研究项目。赵教授和她的学生将开发一系列新的近红外荧光（NIRF）纳米颗粒，用于生物样品中痕量分析物的灵敏检测和成像。所制备的荧光纳米粒子具有高强度和光稳定的荧光信号、清晰的离散激发和发射峰、高水溶性、高生物相容性和低毒性等特点。这些颗粒可能会在生物医学、环境和国土安全应用中找到用途。该项目将为学生提供良好的生物纳米技术培训机会。赵教授将继续她正在进行的教育和推广活动，旨在吸引美国原住民本科生参与她的研究，并向北达科他州的广大受众推广纳米科学领域。

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the research program of Prof. Julia Xiaojun Zhao of University of North Dakota. Prof. Zhao and her students will develop a series of new near-infrared fluorescent (NIRF) nanoparticles for sensitive detection and imaging of trace analytes in biosamples. The resulting fluorescent nanoparticles are expected to show highly intense and photostable fluorescence signals, clearly discrete excitation and emission peaks, high water solubility, high biocompatibility and low toxicity. These particles are likely to find use in biomedical, environmental and homeland security applications. The project will provide excellent training opportunities to students in bionanotechnology. Prof. Zhao will continue her on-going educational and outreach activities aiming to engage Native American undergraduate students in her research and promote the field of nanoscience to a wide audience in the State of North Dakota.
