Optical Trapping and Manipulation in Molecular and Cellular Biology (BT)

Optical Trapping and Manipulation in Molecular and Cellular Biology

Optical TrappingOptical trapping has been widely used to uncover fundamental aspects of molecular and cellular biology, including the understanding of the movement mechanisms of molecular motors and the forces involved in cell adhesion. This group focuses on the development and application of novel optical trapping and manipulation techniques to biological problems. Focus areas include the use of evanescent fields and state of the art optical tweezers for molecular- and cellular-scale manipulation, integration of optical manipulation with microfluidics and lab-on-a-chip technologies, as well as optical sorting and optical methods for cell biology.


Sound or Light: Comparing Optical and Acoustic Trapping for Biomedical Applications

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 been on the rise 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 webinar hosted by the OSA Optical Trapping and Manipulation in Molecular and Cellular Biology Technical Group, Prof. Monika Ritsch-Marte from the Medical University of Innsbruck will compare and contrast the two modalities, and identify situation where one or the other is favorable, or even a combination of both.

Subject Matter Level:

  • Intermediate - Assumes basic knowledge of the topic

What You Will Learn:

  • Optical trapping physical principles and limitations
  • Acoustic trapping physical principles and limitations
  • Applications in biomedical research

  • Physicists, Biologists, Chemists, and Engineers interested in optical trapping, acoustic trapping, biotechnology, biological physics, and biosensing research

About the Presenter: Monika Ritsch-Marte, Medical University of Innsbruck

Monika Ritsch-Marte received her M.Sc. in Physics from the University of Innsbruck in 1984 and her PhD in Quantum Optics from the University of Waikato, New Zealand (under the supervision of D.F. Walls) in 1988. After several PostDoc projects (Boulder/Colorado, Milano, Helsinki), and after completing her Habilitation in the field of Theoretical Physics in the University of Innsbruck, she accepted the Chair of Biomedical Physics at the Medical University of 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.
