Topological insulator particles as optically induced oscillators: towards dynamical force measurements and optical rheology
W. H. Campos, J. M. Fonseca, V. E. de Carvalho +3
We report the first experimental study upon the optical trapping and manipulation of topological insulator (TI) particles. By virtue of the unique TI properties, which have a condu…
Characterizing the Interaction Between DNA and GelRed Fluorescent Stain
F. A. P. Crisafuli, E. B. Ramos, M. S. Rocha
We have performed single molecule stretching experiments and dynamic light scattering (DLS) in order to characterize the interaction between the DNA molecule and the fluorescent st…
DNA-psoralen: single-molecule experiments and first principles calculations
M. S. Rocha, A. D. Lúcio, S. S. Alexandre +2
The authors measure the persistence and contour lengths of DNA-psoralen complexes, as a function of psoralen concentration, for intercalated and crosslinked complexes. In both case…
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…
