  "main_findings": "This paper proposes a simple theory to explain pearl chain formation and alignment of biological particles in liquid media under an applied electric field. The abstract states that alignment is independent of applied field frequency, occurs after a time delay, requires a minimum field strength, and that particles may turn 90 degrees at certain frequencies.",
