This proposal seeks to acquire a Zeiss LSM 880 NOL 3-channel multiphoton confocal laser scanning microscope to upgrade SUNY Binghamton University's (BU) eight-year-old Leica SP 5 single photon confocal microscope that has helped BU faculty to successfully develop top-ranked research programs. The existing microscope was originally configured for thin tissue sample and microorganism imaging. With the expansion of BU research programs in neuroscience, stem cell and regenerative medicine, 3D tissue bioprinting, nanomedicine, etc., the University is in urgent need of a more advanced multiphoton confocal microscope for live cell imaging. LSM880 NOL is a two photon confocal microscope capable of subcellular imaging. Access to this state-of-the-art microscope will propel BU's recent Health Science Initiative, boost faculty research capabilities in Biomedical Engineering, Biological Science, Chemistry, and Psychology Departments and the newly-formed Pharmacy School. It will also help more individuals on campus obtain preliminary results to seek for NSF and NIH funding. The outcome of this project would have a broader impact on our fundamental understanding of how cell and protein behave dynamically in vivo. This project address unmet needs to study cell biology, gene regulation, neuron firing, and tissue regeneration/remodeling in live cells, tissues, and small animals at single cell and single molecule level. Furthermore, its acquisition will foster BU's collaboration with industries to accelerate the translation of life science and biomedical engineering discoveries into bioproducts. A comprehensive management plan will ensure that the instrument always runs at peak and near peak capacity. The strong financial and management commitment from BU and the researchers involved in this project will sustain the facility after the project period.This proposal seeks to acquire a Zeiss LSM 880 NOL 3-channel multiphoton confocal laser scanning microscope to upgrade SUNY Binghamton University's (BU) eight-year-old Leica SP 5 single photon confocal microscope that has helped BU faculty to successfully develop top-ranked research programs. LSM880 NOL is a two photon confocal microscope. Its pulsed, ultrafast infrared laser excites fluorescent dyes or proteins only at the focal point, where photon density is high enough to produce fluorescence. The red excitation light penetrates much deeper into tissue close to 1 mm. It can resolve 140 nm laterally and 400 nm axially at 488 nm, allowing for subcellular imaging. The breadth of research interests, coupled with the current funding of investigators involved in this project poses urgent need for the acquisition of the microscope at BU. The acquisition of this advanced multiphoton microscope will immediately affect more than 17 research labs across six Departments in three schools. More labs will be impacted once the system is set up on campus. The investigators involved in this project are well funded by NSF, NIH, etc. and have research projects that are directly related to the microscope. The acquisition of the instrument will not only permit them to develop more collaborative projects with researchers across the campus, state and nation, but it will also allow faculty to pursue new directions of research and contribute greatly to the growth of BU's research and academic programs. It will enable investigators to study interaction between cell-cell and cell-extracellular matrix; to track cell migration, differentiation, and proliferation; to investigate cell recruitment during wound healing, organ transplantation and tissue regeneration/remodeling; and to measure biochemical reactions such as diffusion, receptors/ligand interaction within live cells, tissues, 3D printed organoids or small animals. Knowledge gained from these studies will significantly advance both bioscience and bioengineering. The acquisition of the microscope will propel and accelerate these advances. It will remarkably enhance BU's research infrastructure in life science and biomedical engineering by providing a multiuser imaging facility that is open to all investigators and students across the campus, state, and nation. Furthermore, it will provide a powerful resource for teaching modern biology and bioengineering. A new lab course focusing on live cell and tissue multiphoton microscopy will be developed and offer to both undergraduate and graduate students. Workshops and open house will be held to train and attract new users to access to the microscope and to reach out to K-12 and local communities, especially those from underrepresented groups. It will offer additional research training opportunities for summer REU students. Finally, it will serve as an excellent recruiting tool for attracting top-notch faculty to the university.

该提案旨在购买蔡司 LSM 880 NOL 3 通道多光子共焦激光扫描显微镜，以升级纽约州立大学宾厄姆顿大学 (BU) 已有八年历史的 Leica SP 5 单光子共焦显微镜，该显微镜已帮助 BU 教师成功开展顶级研究程序。现有的显微镜最初配置用于薄组织样本和微生物成像。随着BU在神经科学、干细胞与再生医学、3D组织生物打印、纳米医学等领域研究项目的扩大，大学迫切需要更先进的多光子共聚焦显微镜进行活细胞成像。 LSM880 NOL 是一款能够进行亚细胞成像的双光子共焦显微镜。使用这款最先进的显微镜将推动波士顿大学最近的健康科学计划，提高生物医学工程、生物科学、化学和心理学系以及新成立的药学院的教师研究能力。它还将帮助校园里更多的人获得初步结果，以寻求 NSF 和 NIH 的资助。该项目的结果将对我们对细胞和蛋白质在体内动态行为的基本理解产生更广泛的影响。该项目解决了在单细胞和单分子水平上研究活细胞、组织和小动物的细胞生物学、基因调控、神经元放电和组织再生/重塑的未满足需求。此外，此次收购将促进 BU 与行业的合作，加速将生命科学和生物医学工程发现转化为生物产品。全面的管理计划将确保仪器始终以峰值和接近峰值的容量运行。 BU 和参与该项目的研究人员的强有力的财务和管理承诺将在项目期结束后维持该设施。该提案旨在购买蔡司 LSM 880 NOL 3 通道多光子共焦激光扫描显微镜，以升级纽约州立大学宾厄姆顿大学 (BU)已有八年历史的 Leica SP 5 单光子共焦显微镜帮助 BU 教师成功开发了一流的研究项目。 LSM880 NOL 是一款双光子共焦显微镜。其脉冲超快红外激光仅在焦点处激发荧光染料或蛋白质，其中光子密度足够高以产生荧光。红色激发光可以更深入地穿透组织，接近 1 毫米。它可以在 488 nm 处横向分辨 140 nm，轴向分辨 400 nm，从而实现亚细胞成像。研究兴趣的广泛性，加上目前参与该项目的研究人员的资金状况，使得波士顿大学迫切需要购买显微镜。购买这款先进的多光子显微镜将立即影响三所学校六个系的超过 17 个研究实验室。一旦系统在校园内建立起来，更多的实验室将受到影响。参与该项目的研究人员得到了NSF、NIH等的大力资助，并且拥有与显微镜直接相关的研究项目。购买该仪器不仅使他们能够与校园、州和国家的研究人员开发更多的合作项目，而且还使教师能够追求新的研究方向，并为波士顿大学研究和学术项目的发展做出巨大贡献。它将使研究人员能够研究细胞-细胞和细胞-细胞外基质之间的相互作用；追踪细胞迁移、分化和增殖；研究伤口愈合、器官移植和组织再生/重塑过程中的细胞募集；并测量活细胞、组织、3D 打印类器官或小动物内的扩散、受体/配体相互作用等生化反应。从这些研究中获得的知识将极大地推动生物科学和生物工程的发展。购买显微镜将推动并加速这些进步。它将通过提供向校园、州和国家的所有研究人员和学生开放的多用户成像设施，显着增强波士顿大学在生命科学和生物医学工程方面的研究基础设施。此外，它还将为现代生物学和生物工程的教学提供强大的资源。将开发一门新的实验室课程，重点关注活细胞和组织多光子显微镜，并提供给本科生和研究生。将举办研讨会和开放日活动，以培训和吸引新用户使用显微镜并接触 K-12 和当地社区，特别是来自代表性不足群体的社区。它将为 REU 暑期学生提供额外的研究培训机会。最后，它将成为吸引顶尖教师到大学的优秀招聘工具。
