Cellular and tissue biosystems emerge from the assembly of their constituent molecules and
obtain a set of specific material properties. To measure these properties and understand …

Over the past decade, optical tweezers (OT) have been increasingly used in neuroscience
for studies of molecules and neuronal dynamics, as well as for the study of model organisms …

In this paper, the optical forces of particles in optical tweezers under non-ideal conditions
are investigated. The calculation of optical forces are carried out by combining three …

This project used mechanical testing and imaging techniques to understand how red blood
cells age in an in vitro environment, and identified markers of red blood cell product quality …

Simulation of optical tweezers involves the calculation of optical and non-optical forces and
torques, modelling the Brownian motion of the particle and combining these components to …

Coiled-coil motifs are part of 5–10% of the eukaryotic proteome and are involved in
important cellular processes such as membrane trafficking, chromosome segregation or …

Cell sorting is pivotal for diagnosing and treating blood diseases. Recently, microfluidic chip-
based methods have streamlined rapid on-chip testing. However, optical force-based cell …

Optomechanical systems are currently being developed to study foundational questions in
quantum mechanics and to push the limits of precision metrology. One particular challenge …

Optical tweezers, a tool for contactless manipulation of micro-and nano-particles, are widely
used to apply and measure forces. This thesis investigates various force measurement …
