小行星9704162 一个近红外拉曼成像显微镜（NIRIM）仪器的2-D光谱化学分析的微复合材料和生物材料将开发和建设在普渡大学化学系系激光设施。 拟议中的仪器建立在显微拉曼和“光镊”技术的最新进展的基础上，以生产一种能力大大超过目前商业或研究仪器的仪器。 特别是，拟议的NIRIM仪器将同时收集来自微复合材料和颗粒的x、y和波长信息的三维数据立方体（具有亚微米空间分辨率和4 cm-1频率分辨率）。 近红外拉曼激发激光器将能够作为一个“光镊”，用于抓取，分离和保持微观和生物颗粒进行化学分析。 这种新仪器将用于各种跨学科的应用，从分子导线、基于沸石的传感器、自组装复合材料、半导体微结构和新型光学数据存储方案的研究，到粘土和冰粒、药物悬浮液、模型膜和活细胞的化学绘图 *

9704162 Ben-Amotz A Near-IR-Raman-Imaging Microscope (NIRIM) instrument for 2-D spectro-chemical analysis of micro-composites and bio-materials will be developed and constructed in the Purdue University Department of Chemistry Departmental Laser Facility. The proposed instrument builds on recent advances in micro-Raman and "optical tweezer" technologies to produce an instrument with capabilities that significantly surpass current commercial or research instruments. In particular, the proposed NIRIM instrument will simultaneously collect 3-D data cubes of x, y and wavelength information from micro-composites and particles (with sub-micron spatial resolution and 4 cm-1 frequency resolution). The near-IR Raman excitation laser will be capable of functioning as an "optical tweezer" used to grab, separate and hold micro- and bio-particles for chemical analysis. This new instrument will be used in a wide variety inter-disciplinary applications ranging from studies of molecular wires, zeolite based sensors, self-assembled composites, semiconductor microstructures and novel optical data storage schemes, to chemical mapping of clay and ice particles, drug suspensions, model membranes and living cells ***
