Atomization is a process of breaking up a liquid into small droplets. This can be done using a variety of methods, such as spraying, misting, or nebulizing. Atomization is often used to create microdroplets for applications such as drug delivery, cosmetics, and agriculture.
Condensation
Condensation is a process of converting a gas into a liquid. When a gas is cooled, it will condense into a liquid if the temperature is below the dew point. Condensation is often used to create microdroplets for applications such as cloud seeding and fog engineering.
Emulsification
Emulsification is a process of creating a stable mixture of two immiscible liquids. This is often done by adding an emulsifier, which is a surfactant that helps to stabilize the mixture. Emulsification is often used to create microdroplets for applications such as food, cosmetics, and pharmaceuticals.

The method of formation can have a significant impact on the properties of microdroplets. For example, atomized microdroplets are typically smaller and more uniform in size than condensed microdroplets. Emulsified microdroplets are typically more stable than atomized or condensed microdroplets.
