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…

Optical tweezers absolute calibration
R S Dutra, N B Viana, P A Maia Neto +1
Optical tweezers are highly versatile laser traps for neutral microparticles, with fundamental applications in physics and in single molecule cell biology. Force measurements are p…
