Function Overview:

Aesthetic Dermal Filler:

In facial minimally invasive procedures, PCL microspheres can be used as injectable fillers to improve facial appearance and restore depressed areas, providing natural, safe, and long-lasting results. PCL microspheres continuously stimulate fibroblasts, promote collagen regeneration, and form a collagen scaffold that stabilizes the microspheres, preventing migration and maintaining a more durable volumizing effect. Compared with traditional hyaluronic acid fillers, PCL-based fillers generally offer longer-lasting outcomes.

Drug Delivery:

PCL microspheres are made from biocompatible and biodegradable medical-grade materials with high crystallinity, leading to relatively slow degradation. This makes them well-suited for long-acting drug delivery systems and the development of sustained-release microsphere injections for a wide range of pharmaceutical agents.

Other Applications:

PCL microspheres can serve as carriers for immobilizing antibodies or antigens, enhancing immunoassay efficiency and sensitivity. For example, in enzyme-linked immunosorbent assays (ELISA), using PCL microspheres instead of traditional flat plates increases the reaction surface area, improving detection accuracy.

Product Advantages:

1. High particle size uniformity with precise controllability to obtain microspheres of varying sizes; good monodispersity.


2. Independent spherical formation, high drug encapsulation efficiency.


3. Gentle sphere formation with low shear and low temperature, avoiding drug damage.


4. Continuous spheronization, no inter-batch variation.


5. Wide range of drug loading, covering various molecular weights and drug types; capable of forming complex structured microspheres (e.g., porous, core–shell)


6. Precise control of sustained-release cycle, easier to extend drug half-life and improve bioavailability compared with structural modification.
