Tailoring optical pulling forces with composite microspheres
R. Ali, F. A. Pinheiro, R. S. Dutra +1
Optical pulling forces or tractor beams can pull particles against light propagation by redirecting the incident photons forward. This is typically achieved using Bessel beams with…

Negative optical torque on a microsphere in optical tweezers
K. Diniz, R. S. Dutra, L. B. Pires +3
We show that the optical force field in optical tweezers with elliptically polarized beams has the opposite handedness for a wide range of particle sizes and for the most common co…

Towards absolute calibration of optical tweezers
N. B. Viana, M. S. Rocha, O. N. Mesquita +3
Aiming at absolute force calibration of optical tweezers, following a critical review of proposed theoretical models, we present and test the results of MDSA (Mie-Debye-Spherical A…
