Non-Technical Description:The University of Puerto Rico - Humacao (UPRH) is enhancing its research, education, and training capabilities with the addition of an atomic force - Raman confocal microscopy (AFM-Raman) instrument. Researchers from UPRH and other institutions in Puerto Rico are using the instrument to advance knowledge in areas at the interface of biology, chemistry, physics, and materials sciences. The research conducted by the group benefits society by developing new materials and devices for health, environmental, energy, and electronics applications. In addition, hundreds of minority undergraduates and high-school students benefit from learning and applying new analytical techniques for their research projects and from the integration of laboratory experiences into science curricula. The outreach program is also enriched by exposing students and teachers to new analytical and imaging techniques. As a result, more minority students are motivated and better trained to pursue advanced degrees and more competitive sciences careers. Finally, the AFM-Raman instrument benefits the larger Puerto Rican research community using UPRH's shared research facilities and promotes the development of new collaborations. Technical Description:AFM-Raman is an integrated solution for simultaneous AFM and confocal Raman, fluorescence, scanning near-field optical microscopy (SNOM), and tip-enhanced Raman scattering (TERS) measurements. The science enabled by this instrument provides relevant societal benefits by contributing to fundamental and applied research in the following projects as examples: (1) study the development of liquid marbles for colorimetric assays with the goal of minimizing pipetting steps, (2) understand the physics and growth dynamics of silver nanoparticles for the development of ultra-sensitive, highly-selective, and low-cost surface-enhanced Raman spectroscopy (SERS) sensors, (3) understand the effect of cellulose functionalization with pillar[n]arenes on trapping and detecting heavy metals and/or organic molecules in water, (4) develop new gallium-derived nanomaterials for drug delivery, sensors, and applications in medicine, (5) develop new sensors and passive electronics using conductive polymers nanofibers blends, (6) understand structure/property relation of carbon-based nanomaterials to develop self-standing and flexible composites with tunable properties for new strain, photo-sensing, and wearable electronics applications, (7) understand the effect of doping agents on the crystal structure of the electrocatalyst zinc oxide use in the oxygen reduction reaction in a fuel cell.This Major Research Instrumentation (MRI) project is jointly funded by the Division of Materials Research (DMR) and the Established Program to Stimulate Competitive Research (EPSCoR).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术描述：波多黎各大学 - 乌马考 (UPRH) 正在通过增加原子力 - 拉曼共焦显微镜 (AFM-拉曼) 仪器来增强其研究、教育和培训能力。 UPRH 和波多黎各其他机构的研究人员正在使用该仪器来推进生物学、化学、物理学和材料科学交叉领域的知识。该小组进行的研究通过开发用于健康、环境、能源和电子应用的新材料和设备来造福社会。此外，数百名少数民族本科生和高中生从学习和应用新的分析技术到他们的研究项目以及将实验室经验融入科学课程中受益。通过让学生和教师接触新的分析和成像技术，外展计划也变得更加丰富。因此，更多的少数族裔学生有动力并接受更好的培训，以追求更高的学位和更具竞争力的科学职业。最后，AFM-拉曼仪器利用 UPRH 的共享研究设施使更大的波多黎各研究界受益，并促进新合作的发展。技术说明：AFM-拉曼是一种集成解决方案，可同时进行 AFM 和共焦拉曼、荧光、扫描近场光学显微镜 (SNOM) 和尖端增强拉曼散射 (TERS) 测量。该仪器所支持的科学通过为以下项目中的基础和应用研究做出贡献，提供了相关的社会效益：(1) 研究用于比色测定的液体弹珠的开发，以尽量减少移液步骤，(2) 了解物理原理和银纳米颗粒的生长动力学，用于开发超灵敏、高选择性和低成本的表面增强拉曼光谱 (SERS) 传感器，(3) 了解柱芳烃对纤维素功能化对捕获和检测水中的重金属和/或有机分子，(4) 开发用于药物输送、传感器和医学应用的新型镓衍生纳米材料，(5) 使用导电聚合物纳米纤维混合物开发新型传感器和无源电子器件，(6) 了解碳基纳米材料的结构/性能关系，以开发具有可调性能的自支撑柔性复合材料，用于新应变、光传感和可穿戴电子应用，（7）了解掺杂剂对晶体结构的影响电催化剂氧化锌在燃料电池氧还原反应中的应用。该重大研究仪器 (MRI) 项目由材料研究部 (DMR) 和刺激竞争性研究既定计划 (EPSCoR) 联合资助。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
