where 𝛾 water-PDMS surface tension, 𝑟 $"" is the radius of the characteristic length 2𝜋𝑟 $"" , and cos 𝜃 is the cosine of the angle between the tangent of the aggregate boundary and the deformed drop boundary (here cos 𝜃 = 1) at the point of de-encapsulation, Force corrections due to Laplace pressure of the drop are accounted for in the surface tension force calculation (𝑅 0 is the radius of the bulk drop) as given by: 𝐹 -. = 𝛾. 2𝜋𝑟 $"" 51 -
