(author), Eral, H.B. (author)Optofluidic devices have revolutionized the manipulation and transportation of fluid at smaller length scales ranging from micrometers to millimeters. We describe a dedicated optical setup for studying laser-induced cavitation inside a microchannel. In a typical experiment, we use a tightly focused laser beam to locally evaporate the solution...journal article 2023

(author), Verweij, M.D. (author), Kooiman, Klazina (author)Ultrasound insonification of microbubbles can locally enhance drug delivery, but the microbubble–cell interaction remains poorly understood. Because intracellular calcium (Ca<sub>i</sub> <sup>2+</sup>) is a key cellular regulator, unraveling the Ca<sub>i</sub> <sup>2+</sup> fluctuations caused by an oscillating microbubble provides crucial...journal article 2020

(author), Verduyn Lunel, Rogier (author), van der Steen, A.F.W. (author), de Jong, N. (author)Controlling microbubble-mediated drug delivery requires the underlying biological and physical mechanisms to be unraveled. To image both microbubble oscillation upon ultrasound insonification and the resulting cellular response, we developed an optical imaging system that can achieve the necessary nanosecond temporal and nanometer spatial...journal article 2019
