Optical trapping and manipulation of fluorescent polymer-based nanostructures: measuring optical properties of materials in the nanoscale range
T. A. Moura, M. L. Lana Júnior, C. H. V. da Silva +5
We present a novel approach to determine the optical properties of materials in the nanoscale range using optical tweezers (OT). Fluorescent polymer-based nanostructures (pdots) ar…

On the use of organic semiconductors as handles for optical tweezers experiments: trapping and manipulating polyaniline (PANI) microparticles
Kairon M. Oliveira, Tiago A. Moura, Janaisa L. C. Lucas +3
Here we propose the use of the organic semiconductor polyaniline (PANI) for the preparation of spherical-shaped microparticles to serve as handles in optical tweezers (OT) experime…

Germanium microparticles as optically induced oscillators in optical tweezers
W. H. Campos, T. A. Moura, O. J. B. J. Marques +4
Oscillatory dynamics is a key tool in optical tweezers applications. It is usually implemented by mechanical interventions that cannot be optically controlled. In this work we show…
