Patchy particles are a type of colloidal particle or nanostructure that possess specific, localized regions or "patches" with distinct chemical or physical properties. These patches can be designed to have different functionalities—such as hydrophobic or hydrophilic characteristics, or specific binding affinities—for the purpose of creating complex structures or assemblies. The unique surface properties of patchy particles allow them to interact selectively with other particles or molecules, enabling the formation of diverse and complex structures at the nanoscale.
