This method offers high yield and good particle size distribution, making it suitable for large-scale production.
Solvent Diffusion Method
In this method, PCL is dissolved in a solvent, and the solvent is gradually diffused into the aqueous phase to form nanoparticles. By precisely controlling the diffusion rate of the solvent, nanoparticles with uniform size can be obtained. BOC Sciences utilizes efficient ultrasonic technology in this process to ensure particle uniformity and stability.
Spray Drying Method
Spray drying is an efficient preparation method suitable for large-scale nanoparticle production. BOC Sciences uses a spray device to atomize PCL solution and rapidly evaporate the solvent in a drying airflow to obtain nanoparticles. This method enables the rapid production of smaller particles with high production efficiency.
Ultrasonic Method
The ultrasonic method uses high-frequency vibrations from ultrasonic waves to disperse PCL solution into nanoparticles. BOC Sciences combines ultrasonic dispersion technology to quickly obtain high-quality PCL nanoparticles, suitable for small batch and high-precision preparation needs.
