Giant conductance of PSS:PEDOT micro-surfaces induced by microbubble lithography

Anand Dev Ranjan, Rakesh Sen, Sumeet Kumar +5

We provide direct evidence of the effects of interface engineering of various substrates by Microbubble lithography (MBL). We choose a model organic plastic (or polymer) poly(3,4-e…

Roadmap for Optical Tweezers

Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80

Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…

Simultaneous optical trapping and magnetic micromanipulation of ferromagnetic iron-doped upconversion microparticles in six degrees of freedom

Gokul Nalupurackal, Gunaseelan M, Muruga Lokesh +9

Optical trapping of magnetic Fe-oxide particles is notoriously difficult due to their high refractive indices, not to mention high absorptivity at the trapping infra-red wavelength…

Detection of sub-degree fluctuations of the local cellmembrane slope using optical tweezers

Rahul Vaippully, Vaibavi Ramanujan, Manoj Gopalakrishnan +2

Normal thermal fluctuations of the cell membrane have been studied extensively using high resolution microscopy and focused light, particularly at the peripheral regions of a cell.…

Pitch-rotational manipulation of single cells and particles using single-beam thermo-optical tweezers

Sumeet Kumar, M. Gunaseelan, Rahul Vaippully +5

3D pitch rotation of microparticles and cells assumes importance in a wide variety of applications in biology, physics, chemistry and medicine. Applications such as cell imaging an…

In-vivo characterization of optically trapped Brownianprobes at a glance

Rahul Vaippully, Vaibavi Ramanujan, Saumendra Bajpai +1

Calibration of optically trapped particles in-vivo has been complicated given the frequency dependence and spatial inhomogeneity of the cytoplasmic viscosity, and the requirement o…
