An award is made to Northwestern University and the City University of New York to develop an instrument capable of synthesizing arbitrary 3D nanopatterns of biologically active materials, coined “the Nanosizer.” The development of said instrument, the instrument itself, and the new photochemistry developed, will have wide reaching impacts on trainees, the nearby Chicago and New York City communities, and the broader scientific community. Both Mirkin and Braunschweig groups have previously and will continue to mentor trainees, including undergraduates, graduate students, and postdoctoral fellows, on the design of experiments and communication skills. Importantly, the researchers will lead the experimentation effort and work closely with the PIs on the dissemination of results through high-impact publications, patents, grant reports, and conference presentations. Exposure to all aspects of the research process will provide trainees with the highest probability of success on their paths forward, as proven by the track record of academic and industrial job placement from the two groups. The neighboring Chicago and New York communities stand to benefit from the award, through participation in outreach endeavors. Braunschweig group will participate in the Research Internships in Materials Science and Mirkin members will volunteer with Science In your Community Center with the goal of engaging K-12 students, primarily those from traditionally underrepresented groups, in science and technology. The Nanosizer will make arbitrary 3D nanopatterns of biologically active macromolecules with 100 nm resolution a reality through in situ surface patterning and fully orthogonal biomacromolecule construction. Through a combination of beam-pen lithography with 100 nm pixel resolution, precise multiwavelength irradiation control, and continuous flow of variable reagent streams, the Nanosizer will enable control over the reaction conditions at any 100 nm pixel over a 1 cm2 area. This, in conjunction with the development of orthogonal photochemistries for surface functionalization and synthesis of biomolecules, such as oligopeptides, oligonucleotides, and glycans, will enable the massively parallel generation of biomolecule arrays, with each pixel containing a chemically unique and well-defined molecule. Synthetic interfaces coated with biologically active materials have screening and functional applications in nearly every field of biology. The Nanosizer will provide monumental improvements in batch-to-batch reproducibility, resolution size, feature density, feature quantity, and overall cost in the preparation of such substrates. Results from these studies will be published in peer-reviewed journals, presented at scientific meetings, broadly distributed through commercialization, and incorporated into outreach presentations.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.

西北大学和纽约城市大学获得了一项奖项，开发一种能够合成生物活性材料的任意 3D 纳米图案的仪器，并创造了“Nanosizer”。该仪器的开发、仪器本身以及新光化学的开发。将对受训者、附近的芝加哥和纽约市社区以及更广泛的科学界产生广泛的影响，米尔金和布伦瑞克团体此前已经并将继续指导受训者，包括本科生、研究生、重要的是，研究人员将领导实验工作，并与 PI 密切合作，通过高影响力的出版物、专利、资助报告和会议演示来传播结果。研究过程的各个方面将为受训者提供最大的成功机会，这两个团体的学术和工业就业记录证明，他们将从该奖项中受益。 ，通过参与布伦瑞克小组将参加材料科学研究实习，Mirkin 成员将在您的社区中心担任志愿者，目标是吸引 K-12 学生（主要是来自传统上代表性不足的群体）参与科学和技术。通过束笔的组合，通过原位表面图案化和完全正交的生物大分子结构，使具有 100 nm 分辨率的生物活性大分子的任意 3D 纳米图案成为现实。 Nanosizer 具有 100 nm 像素分辨率的光刻、精确的多波长照射控制和可变试剂流的连续流动，结合正交光化学的发展，可以控制 1 cm2 面积上任何 100 nm 像素的反应条件。用于寡肽、寡核苷酸和聚糖等生物分子的表面功能化和合成，将能够大规模并行生成生物分子阵列，每个阵列含有化学上独特且明确的分子的合成界面在几乎所有生物学领域具有筛选和功能应用，将在批次间的再现性、分辨率尺寸、特征密度、这些研究的结果将发表在同行评审期刊上，在科学会议上发表，通过商业化广泛传播，并纳入推广演示中。通过使用基金会的智力价值和更广泛的影响审查标准进行评估，NSF 的法定使命被认为值得支持。
