Immersive polymer assembly on immobilized particles for automated capsule preparation

Abstract

We report a versatile approach for polymer capsule preparation using immobilized particles, which are immersed into polymer solutions either manually or by using an automated robotic dipping machine. This technique produces polyelectrolyte capsules with improved retention over conventionally prepared capsules. Additionally, responsive hydrogel capsules of different diameter can be prepared simultaneously.
