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…

Probing inhomogeneous and dual asymmetric angular momentum exploiting spin-orbit interaction in tightly focused vector beams in optical tweezers
Ram Nandan Kumar, Jeeban Kumar Nayak, Anand Dev Ranjan +3
The spin-orbit interaction (SOI) of light generated by tight focusing in optical tweezers has been regularly employed in generating angular momentum - both spin and orbital - in tr…

Study of adhesivity of surfaces using rotational optical tweezers
Rahul Vaipully, Dhanush Bhatt, Anand Dev Ranjan +1
Optical tweezers are powerful tools for high resolution study of surface properties. Such experiments are traditionally performed by studying the active or the brownian fluctuation…
