Intelligent microrobot DDS (drug delivery system) measured and controlled by ultrasonics

Abstract

Proposes a new concept of a micro-robot drug delivery system (DDS) in which drug-carriers of air-filled microcapsules are measured with echography and are controlled with resonant ultrasound. The authors have confirmed physical possibility of resonance design of drug-carriers depending on shell structure of microcapsule. Furthermore, as a measurement system for microrobot DDS, they have developed novel echographic imaging system. Path lines of microcapsules in the blood flow were clearly visualized.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
