Precise manipulation and sorting of nanomaterials cannot rely on techniques used for micro-
and macro-scale objects because of their nanoscale size, which is smaller than the …

The integration of optical circuits with microfluidic lab-on-chip (LoC) devices has resulted in
a new era of potential in terms of both sample manipulation and detection at the micro-scale …

Fourteen years ago, optical lattices and holographic tweezers were considered as a
revolution, allowing for trap** and manipulating multiple particles at the same time using …

Due to the action of the scattering force, particles that are optically trapped at the surface of a
waveguide are propelled in the direction of the light propagation. In this work, we …

Although photonic waveguides have been often used as on-chip optical conveyor belts for
transporting trapped particles, we demonstrate here an all-optical approach to create …
