This Major Research Instrumentation RUI grant supports acquisition of a 5-watt, 532 nm, CW laser and research-grade microscope so that the research on new particle trapping methods and on the interactions between particles in optically-bound structures can advance. Holographic techniques significantly extend the capabilities of laser tweezing, making possible optical manipulation of matter into complex two- or three-dimensional patterns and shapes containing large numbers of particles. This will also provide essential, on-campus research opportunities and will result in greater undergraduate research involvement. This instrumentation makes possible new course modules geared toward research training that will be shared with the larger community. Illinois Wesleyan University (IWU) students have helped to develop two techniques for non-lithographic means of assembly. The new instrumentation is essential to allow this research team to continue to develop further techniques. Moreover, this instrumentation offers novel opportunities for initiative in the undergraduate curriculum, affecting biology and physics majors, as well as pre-engineering students. %%%Organizing micro-and nano-components into larger structures or assemblies is crucial to many activities and disciplines. The technologies which the IWU research team has demonstrated have the potential to impact research in biology and bio-engineering, the field of micro-electro-mechanical devices, and many other fields where progress has been restricted by the need to configure non-lithographic structures at the microscopic level. The most noticeable impact may come in the field of Photonics: fiber-optic communication networks may benefit from the ability to engineer "photonic-bandgap" devices, which could play the same role in optics that semiconductors have played in the electronics industry. ***

这项主要的研究仪器RUI赠款支持获得5瓦，532 nm，CW激光和研究级显微镜的获取，以便可以提高对新粒子捕获方法的研究以及光学结合结构中粒子之间的相互作用。全息技术显着扩展了激光镊子的能力，使得物质的光学操纵可能分解为复杂的两维模式和包含大量颗粒的形状。这还将提供必不可少的校园研究机会，并将导致更多的本科研究参与。该仪器使得将与更大的社区共享的研究培训的新课程模块可能。伊利诺伊州卫斯理大学（IWU）的学生帮助开发了两种针对非载体组装手段的技术。新仪器对于允许该研究团队继续开发进一步的技术至关重要。此外，该仪器为本科课程提供了新的主动性机会，影响了生物学和物理专业的专业以及工程学的学生。 %%％将微型和纳米组件组织到较大的结构或组件中对于许多活动和学科至关重要。 IWU研究小组证明的技术有可能影响生物学和生物工程研究，微机械设备领域以及许多其他领域，这些领域的进步受到了不合格的不庞大结构的限制。在微观水平上。最明显的影响可能会引起光子学领域：光纤通信网络可能会受益于工程“光子式袋鼠”设备的能力，该设备在光学方面可能扮演与半导体在电子行业中扮演的角色相同的角色。 ***
