The first project explores non equilibrium dynamics of a particle driven by ultrasonic vibrations. We design an experimental system consisting of an electromechanical vibration scheme to drive the particle’s vibrations and an imaging scheme to track its trajectories. We study the trajectories to determine how the particle’s dynamics evolve under the driven conditions, considering out of equilibrium systems in the context of equilibrium statistical mechanics. Using a Langevin framework and the Boltzmann factor, we characterize the particle’s dynamics as complex; the particle motion\r\nis not purely diffusive. We extract physical parameters like spring constant, effective temperature, damping coefficient and resonance frequency.\r\n\r\nIn the second project, we explore and develop techniques in the design and microfabrication of particles across scales. Microfabrication involves building structures at the micron or submicron scale. These designed miniaturized patterns, objects, or devices are useful in biophysics, pharmacology, medical biology, and nanotechnology. We specifically apply two-photon polymerization, a form of 3D nano printing. We print millimetric particles, characterizing different designs to evaluate and showcase the resolution, aspect ratio integrity and print quality of the printing process. We also design and fabricate a microsensor to deflect under applicable force of order 0.1 pN. We present fundamental concepts needed to design the microsensor, showcasing 3D printing at considerably smaller scales down to the µm or below.","lang":"eng"}],"ddc":["530"],"doi":"10.15479/at:ista:18588","oa":1,"acknowledgement":"I would like to acknowledge Scott Waitukaitis and Jérémie Palacci, for their supervision, and their extensive support of my learning. \r\n\r\nFor the beautiful characterization images used in this work, I would like to thank Dr. Daniel Grober, Samuel Hajek and Felix Pertl.\r\n\r\nThe Palacci group, particularly Malina Strugaru and Dan Grober, for their continuous guidance in decoding and following my streams of thought.\r\n\r\nTo the Waitukaitis group, for helping me find my footing in science, and making me feel at\r\nhome.\r\n\r\nTo the Nanofabrication Facility (NFF) at ISTA, for training me in significant aspects of my research.
