We show that loosely packed homogeneous monolayers of soft colloidal particles can be fabricated via simple evaporative drying of aqueous dispersion containing colloidal particles. Owing to the inherent amphiphilicity of the soft microgels, they are preferentially adsorbed onto the water-vapor interface of the drying droplet, resulting in a uniform deposition of the particles throughout the fluid-substrate contact area. Distinct order-to-disorder transition is also identified within the dried deposits on changing spatial locations from edge to center of the circular stain. Such monolayer deposits exhibit vibrant colors on irradiating with white light due to interference. © 2019 Author(s).
