  text: "This thesis is an experimental work about two distinct research projects
    that evolved from a single project: non-equilibrium dynamics of an acoustically
    vibrated particle and microfabrication of particles with nano-scale 3D printing.
    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."

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. The MIBA Facility,
  and particularly Todor Asenov for consistently picking up the phone for my machining
  and designing needs.\r\n\r\nTo my friends, Mariana, Lenka, Aaron, Rebecca, Eavan
  who provided an ear, wine, and a lot more when I needed to vent, talk through my
  crises as well as experiment. For the walks, for the coffees, for reading through
  my work and providing edits, for dinners to take me out of blocks and binds and
  for cheering me on when it felt insurmountable. \r\n\r\nFinally, I am grateful to
  Griff and Fletcher, whose music helped me through several blocks, especially with
  my writing.\r\n\r\nMy science would not have been possible without the guidance,
  support and contributions of\r\nall these people, and more."
