PSI has developed a proprietary aqueous microencapsulation technology, which allows fabrication of polyphosphazene microspheres with narrow size distribution and an extremely broad range of sizes from 200 nm to 500 µm. The advantages of the Company’s methodology include simplicity and speed of microsphere preparation, mild encapsulation conditions, and the precise control of microsphere architecture and size.

This microencapsulation technology is also high throughput enabled and can be applied to many of PSI’s library compounds. This feature, in combination with the design control afforded by polyphosphazene chemistry generally, facilitates the development and manufacture of microspheres with designed characteristics such as modulated release profiles and controlled erosion/degradation rates.

This technology may be applied to a variety of applications across both the life science and advanced material applications.
