Photophoretic Trapping: Fundamentals, Advances and Future Directions
Anita Pahi, Kirty Ranjan Sahoo, Souvik Sil +1
Photophoretic forces, several orders of magnitude stronger than radiation pressure, enable particle trapping at remarkably low optical intensities and have opened pathways to appli…

Simultaneous active and diffusive behaviour of asymmetric microclusters in a photophoretic trap
Anita Pahi, Kirty Ranjan Sahoo, Biswajit Das +2
Active and diffusive motion in Brownian particles are regularly observed in fluidic environments, albeit at different time scales. Here, we experimentally study the dynamics of hig…
