Abstract

This project explores the use of microbubble lithography (MBL) for developing multilayer heterostructures with unique properties. MBL is one of the best bottomup approaches to building desired patterns of dispersed material in a colloidal dispersion. It is thus a promising technique for creating complex structures with high resolution. The development of multilevel hetero-structures is possible by running MBL again with a colloid of the required material. The potential applications of these structures are numerous, including in fields like optical sensing and biomedical research, one of which is explored in depth here. Hydrogen Peroxide (H₂O₂) is an oxidizing reagent. Therefore, its detection at a mesoscopic scale may be highly relevant in biomedical fields. This research aims to optimize and use the optimized multilevel hetero-structures as stable platforms of the mesoscopic scale for the detection of (H₂O₂) even at very low concentrations through fluorescence quenching of Rhodamine 6G. Overall, this work emphasizes the importance of exploring the fabrication of heterostructures using MBL and the diverse areas where it can be used.
