Tuning pair interactions in colloidal systems using random light fields
Augustin Muster, Diego Romero Abujetas, Frank Scheffold +1
We propose a method to tune interactions between absorptionless colloidal particle pairs. This is achieved via optimization of the spectral energy density of a homogeneous random o…

Assessing the pair interactions of pNIPAM microgel particles using optical tweezers
José Muñetón-DÃaz, Chi Zhang, Priti Mohanty Priti +1
We experimentally study the pairwise interactions between poly(N-isopropylacrylamide) (pNIPAM) microgel particles using line optical tweezers. To measure their interaction potentia…
