The aim of this thesis is to provide greater insight into targeted drug delivery using magnetically actuated millirobots. Specifically, this thesis will focus on the relationship between the lifespan of these millirobots and the magnetic oscillation frequency under zero-flow conditions.
Lifespan will be estimated by observing the decrease in volume, or in other words, degradation, of the millirobot over time. This degradation will be measured at various oscillation frequencies to identify a correlation between the two variables. The degradation of the millirobots will be observed using confocal microscopy equipped with a camera system to capture real-time footage. To accurately quantify the volume decrease, video analysis software will be used to evaluate the footage. The millirobot is made of (??), which was chosen because (???). Since the human body contains fluids with varying viscosities, resulting in different degradation rates, zero-flow conditions were selected to eliminate the viscosity variable and establish a baseline for evaluating the relationship between millirobot lifespan and magnetic oscillation frequency.
Understanding this relationship will offer insights into potential sites for targeted drug delivery, limitations of the current millirobot design, constraints of the selected material, and suitable magnetic oscillation·frequencies.
