Comparing Optical and Acoustic Trapping for Biomedical Applications

Monika Ritsch-Marte from the Medical University of Innsbruck gives a talk as part of the Distinguished Lecturer Series of the Max Planck Institute for the Science of Light. The series brings leading minds in all areas relevant to the science of light to Erlangen. It presents the unique opportunity for scientific exchange with the speakers to a broad audience.


Many biomedical investigations require to move, stretch or mechanically probe a biomedical sample by exerting controlled forces in a non-contact way. Thus optical and acoustic trapping of microscopic samples have found a multitude of applications in recent years. The differences in the physical laws and in the typical length scales governing acoustic and optical forces make them complementary. While acoustic forces can levitate large and therefore heavy particles, which optical tweezers could not handle without adverse high-power effects, optical forces cover subcellular scales. In this talk I will compare and contrast the two modalities, and identify situation where one or the other is favorable, or even a combination of both.


Monika Ritsch-Marte received her M.Sc. in Physics from the University of Innsbruck in 1984 and her PhD in Quantum Optics from the Waikato University in New Zealand (under the supervision of D.F. Walls) in 1988. After several PostDoc projects (Boulder/Colorado, Milano, Helsinki), and after completing her Habilitation at the Institute of Theoretical Physics in Innsbruck, she accepted the Chair of Biomedical Physics at the Medical University in Innsbruck in 1998 where she founded a Biomedical Optics group. Her current research interests include holographic optical tweezers, digital holographic microscopy and linear and non-linear Raman microscopy. She has received numerous research grants and awards, including an ERC Advanced Grant and the Boltzmann Award of the Austrian Physical Society. She is a member of the Austrian Academy of Science, the German Academy Leopoldina, and a Fellow of the Optical Society of America.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
