Optical fibre sensors make use of diverse physical effects to measure parameters such as
strain, temperature and electric field. Here we introduce a new class of reconfigurable fibre …

Herein, charged microbeads handled with optical tweezers are used as a sensitive probe for
simultaneous measurements of electrophoretic and dielectrophoretic forces. We first …

We report an electric field sensor based on a charged microparticle that is optically trapped,
and moved to and fro, inside a hollow-core photonic crystal fibre (PCF). Transverse electric …

Optical trapping enables measuring and exploiting tiny forces that are exerted on micron-
sized particles. Inserting a microparticle into the air-filled hollow core of a photonic crystal …

Optical trapping is a tool used throughout a wide variety of disciplines rang-ing from
precisely probing and manipulating sub-micron organisms in biol-ogy to analyzing …

Hollow-core photonic crystal fiber (HC-PCF) confines and guides light in its hollow core.
When a dielectric microparticle is launched into the core, optical forces generated by the …

“Smaller, faster, and cheaper” is the mantra referred to a huge number of commercial
products which are of interest for a very large market, spanning from high-tech devices to …

The electric charge and the hydrodynamic coefficient and of bacterial spores are key
parameters in protein binding to spores and in the adhesion of spores onto surfaces. Using …

We present an experimental platform which combines spectroscopic capabilities with time-
resolved measurements of effective surface charge at solid-liquid interfaces. Silica …
