Polymer particles are microscopic to nanoscopic entities composed of polymeric material. They are formed through various polymerization techniques or by processing pre-existing polymers. The size, shape, and surface properties of polymer particles can be precisely controlled, making them versatile for a wide range of applications.

These particles can be either solid spheres or hollow structures, often referred to as microcapsules or nanocapsules, depending on their construction. The polymer matrix can be a homopolymer, copolymer, or a blend of different polymers. Surface modifications are frequently employed to impart specific functionalities, such as hydrophilicity, hydrophobicity, or the ability to conjugate with biomolecules.

Polymer particles find use in diverse fields. In drug delivery, they encapsulate therapeutic agents, offering controlled release and targeted delivery. In diagnostics, they serve as carriers for imaging agents or as components in biosensors. They are also utilized in coatings and paints to enhance properties like scratch resistance and durability. Furthermore, they play a role in advanced materials, including composites and membranes, and are employed in environmental applications for water purification and pollutant removal. The development and application of polymer particles continue to expand as researchers explore new synthesis methods and innovative uses.
