Abstract

Graphical abstract

Nanosphere lithography (NSL) is a bottom‐up, self‐assembly approach that enables rapid, low‐cost patterning of nanoscale features. The practical application and scalability of NSL relies on the ability to achieve defect‐free nanosphere self‐assembly over large substrate areas. Self‐assembly methods for single‐layer nanosphere templates are typically evaluated using scanning electron microscopy (SEM) imaging, with literature reports focusing on maximum area of continuous nanosphere coverage. An alternative performance metric—namely, the percentage of nanospheres exhibiting perfect hexagonal close‐packing (%HCP)—is uniquely critical to NSL precision and repeatability. To enhance current methods of evaluating nanosphere self‐assembly, this work presents an SEM image analysis approach for rapidly quantifying packing defects in single‐layer nanospheres to determine %HCP. The method uses variations in SEM edge effect brightness to distinguish spheres with perfect packing from those in defect configurations or along edges. Comparison of image analysis program results with manual counting of nanospheres indicates that the program has a high degree of accuracy, with a mean error on the %HCP metric of +8.6% (absolute error). The results suggest that the present strategy offers a promising pathway to rapid evaluation of nanosphere self‐assembly for high‐precision NSL applications such as surface‐enhanced Raman scattering, photovoltaic cells, and nanogap electrodes.

 

February 2020: Warren receives NSF CAREER Award

Department of Mechanical Engineering Assistant Professor Roseanne Warren has been awarded a National Science Foundation Faculty Early Career Development Program (CAREER) award. The CAREER program is one of NSF’s most prestigious award programs, with awards of up to $500,000 over 5 years in support of early-career faculty with potential to serve as academic role models in research and education. The research grant, entitled “CAREER: Roll-to-Roll Fabrication of Porous Materials Using Nanobubble Templates,” will explore new methods of fabricating templated porous materials that are compatible with high-throughput, scalable manufacturing protocols, including roll-to-roll fabrication.

September 2019: Lab-on-a-Chip cover article published

Abdullah Alsharhan, Ruben Acevedo, Roseanne Warren, and Ryan Sochol’s recent article, “3D microfluidics via cyclic olefin polymer-based in situ direct laser writing” has been featured on the front cover of the September 7, 2019 issue of Lab on a Chip. The article explores a new method of printing three-dimensional nanostructured components directly inside of enclosed microchannels using cyclic olefin polymer (COP). Demonstrated 3D printing results show that COP-based in-situ direct laser writing offers a promising pathway to wide-ranging fluidic applications that demand significant architectural versatility at submicron scales with invariable sealing integrity, such as for biomimetic organ-on-a-chip systems and integrated microfluidic circuits.

The research is supported by NSF Award numbers 1761395 and 1761273.
