We experimentally demonstrated that dielectrophoretic (DEP) forces of alternating
photovoltaic fields generated near the surface of a photorefractive Fe-doped lithium niobate …

The non-diffracting Bessel beam approach was used for the first time for the elaboration of
photovoltaic tweezers. We report the trapping of dielectric microparticles of chalk (CaCO 3) …

This thesis presents the innovative study on the local modification of surface wettability
actuated by light by exploiting the photovoltaic properties of a photorefractive material, a …

We study the controlled trapping and manipulation of micro-and nanoobjects using a slowly
light-induced increasing electric field in a photovoltaic ferroelectric crystal. By employing a …

Currently, there is increasing interest from many scientific disciplines in the development of
systems that are able to sort and arrange many objects in parallel at the nano-and …

Photovoltaic optoelectronic tweezers are a useful platform with many applications in optical
