Speckle tweezers at fluid-fluid interface

Ramin Jamali, Sabareesh K. P. Velu, Ali-Reza Moradi

Contemporary approaches to optical multiple micro-manipulation typically involve careful pre-engineering of the laser beam shape. In various biomedical and microfluidic scenarios,…

Speckle Tweezers for Simultaneous Controlling of Low and High Refractive Index Micro-particles

Ramin Jamali, Farzaneh Nazari, Azadeh Ghaffari +2

Manipulation of micro and nanoscale particles suspended in a fluidic medium is one among the defining goals of modern nanotechnology. Speckle tweezers (ST) by incorporating randoml…

Ordering of Binary Colloidal Crystals by Random Potentials

Andre S. Nunes, Sabareesh K. P. Velu, Iryna Kasianiuk +6

Structural defects are ubiquitous in condensed matter, and not always a nuisance. For example, they underlie phenomena such as Anderson localization and hyperuniformity, and they a…

Clustering of Janus Particles in Optical Potential Driven by Hydrodynamic Fluxes

S. Masoumeh Mousavi, Sabareesh K. P. Velu, Agnese Callegari +2

Self-organisation is driven by the interactions between the individual components of a system mediated by the environment, and is one of the most important strategies used by many…

Active Matter Alters the Growth Dynamics of Coffee Rings

Tugba Andac, Pascal Weigmann, Sabareesh K. P. Velu +4

How particles are deposited at the edge of evaporating droplets, i.e. the {\em coffee ring} effect, plays a crucial role in phenomena as diverse as thin-film deposition, self-assem…

Near Field Speckles The Optical Theorem Revisited

Sabareesh K. P. Velu

The zero angle scattered wave plays an essential role in the celebrated Optical Theorem that relates the total extinction cross section (including both scattering and absorption) t…

Colloidal Assemblies of Oriented Maghemite Nanocrystals and their NMR Relaxometric Properties

A. Kostopoulou, S. K. P. Velu, K. Thangavel +7

Elevated-temperature polyol-based colloidal-chemistry approach allows for the development of size-tunable (50 and 86 nm) assemblies of maghemite iso-oriented nanocrystals, with enh…
