The influence of frequency and gravity on the orientation of active metallo-dielecric Janus particles translating under a uniform applied alternating-current electric field
Alicia Boymelgreen, Golak Kunti, Pablo Garcia Sanchez +1
Theoretical and numerical models of active Janus particles commonly assume that the metallo-dielectric interface is parallel to the driving applied electric field. However, our exp…
On-Chip Concentration and Patterning of Biological Cells Using Interplay of Electrical and Thermal Fields
Golak Kunti, Tarun Agarwal, Anandaroop Bhattacharya +2
We demonstrate a method of concentrating and patterning of biological cells on a chip, exploiting the confluence of electric and thermal fields, without necessitating the use of an…
Energy-Efficient Micromixing in Paper Based Devices Mediated by the Interplay of Electrical and Thermal Fields
Golak Kunti, Sankha Shuvra Das, Vinay Manaswi Pedireddi +2
