The growth and self-assembly of molecules on surfaces can be directly visualized at the molecular level using studies which combine nanoscale lithography and high-resolution imaging. Nanopatterning provides a unique and practical approach for direct views of surface changes after the key chemical steps of nanopatterning, providing landmarks and baselines for measuring growth in vertical and lateral dimensions. Controlling the arrangement of materials on surfaces at the nanoscale can be achieved using particle lithography. Arrays of well-defined nanostructures can be prepared with reproducible geometries and arrangement. Results for the preparation of nanopatterns produced with particle lithography are presented using high resolution …
Nanoscale Studies Of Proteins And Thin Films Using Scanning Probe Microscopy, Zachary Lane Highland
Nanoscale Studies Of Proteins And Thin Films Using Scanning Probe Microscopy, Zachary Lane Highland
LSU Doctoral Dissertations
Nanostructures of organosilanes, thin metal films, and protein nanopatterns were prepared and analyzed with atomic force microscopy (AFM). Organosilanes with designed functional groups were used to selectively pattern green fluorescent protein at the nanoscale using protocols developed with particle lithography. Mesospheres are deposited onto a substrate to produce a surface mask. Organosilanes are deposited to form a matrix film surrounding nanopores for depositing proteins. The nanopatterns were characterized using AFM, after steps of particle lithography for directly visualizing surface changes. Studies with AFM also provide a compelling tool for teaching undergraduates to introduce concepts of nanoscience. An undergraduate laboratory was …

This dissertation focuses on the diverse use of chemical synthesis. Herein, I will discuss the use of synthetic organic chemistry for the modification surfaces and the synthesis of small molecules. Chapter One is an introduction to the realm of surface chemistry. I have highlighted some key methods for surface modification. Additionally, methods to characterize the as-formed thin films are also outlined. In Chapter Two, I discuss the use of visible-light photoredox catalysis in the nanoscale lithography of Au(111) surfaces. Blue LED irradiation of solutions of NBDT in the presence of Ru(bpy)32+ results in the formation of p-nitrophenyl radicals that graft …
