Elasticity-mediated Morphogenesis in Interfacial Colloidal Assemblies
Vaibhav Raj Singh Parmar, Sayantan Chanda, Rituparno Mandal +1
We study the self-assembly of colloidal microgel particles at a quasi-two-dimensional air-water interface of a drying droplet. Using bright-field microscopy, we demonstrate that in…

Investigating the roles of hydrophobicity and electrostatics in the particle-scale dynamics and rheology of dense microgel suspensions
Sayantan Chanda, Chandeshwar Misra, Ranjini Bandyopadhyay
Colloidal microgel particles such as poly(N-isopropylacrylamide) (PNIPAM) shrink reversibly in an aqueous medium due to the expulsion of water at a volume phase transition temperat…

Using optical tweezer electrophoresis to investigate clay nanoplatelet adsorption on Latex microspheres in aqueous media
Vaibhav Raj Singh Parmar, Sayantan Chanda, Sri Vishnu Bharat Sivasubramaniam +1
The adsorption of charged clay nanoplatelets plays an important role in stabilizing emulsions by forming a barrier around the emulsion droplets and preventing coalescence. In this…
