Laser surface patterning by Contact Particles Lens Arrays (CPLA) has been widely utilized for patterning of smooth surfaces but there is no technique developed by which CPLA can be deposited on a rough surface. For deposition of CPLA, conventional techniques require the surface to be flat, smooth and hydrophilic. In this study, a new method for the deposition of CPLA on a rough surface is proposed and utilized for patterning. In this method, a hexagonal closed pack monolayer of SiO2 spheres was first formed by self-assembly on a flat glass surface. The formed monolayer of particles was picked up by a flexible sticky surface and then placed on the rough surface to be patterned. A Nd:YVO4 laser was used to irradiate the substrate with the laser passing through the sticky plastic and the particles. Experimental investigations have been carried out to determine the properties of the patterns.

Initial Results

ABSTRACTThe interest for surface patterning presents a fast increasing in the last few years due to several factors ranging from miniaturization trends and sensor design to worries about the absorption of carcinogenic molecules on inhalable particles. Although the existence of a vast literature regarding the self-assembly and patterning of nanoparticles on different types of surfaces, it remains unclear the dynamics and main mechanisms behind the formation and maintenance of two-dimensional symmetric patterns of small molecules on top of surfaces. In this contribution, we report initial results on an investigation on the similarities between the well-known Abrikosov hexagonal lattices in superconductors, and the spontaneous formation of hexagonal patterns of some small polycyclic aromatic hydrocarbons (PAHs) on top of a graphitic surface. In order to attest our results, some experimental results from literature are compared to the obtained results.

Living systems achieve robust self-assembly across length scales. Meanwhile, nanofabrication strategies such as DNA origami have enabled robust self-assembly of submicron-scale shapes.However, erroneous and missing linkages restrict the number of unique origami that can be practically combined into a single supershape. We introduce crisscross polymerization of DNA-origami slats for strictly seed-dependent growth of custom multi-micron shapes with user-defined nanoscale surface patterning. Using a library of ~2000 strands that can be combinatorially assembled to yield any of ~1e48 distinct DNA origami slats, we realize five-gigadalton structures composed of >1000 uniquely addressable slats, and periodic structures incorporating >10,000 slats. Thus crisscross growth provides a generalizable route for prototyping and scalable production of devices integrating thousands of unique components that each are sophisticated and molecularly precise.
