PBD-B-0.25 | Biodegradable microparticles, no surface modification, blue fluorescence, 250 nm diameter

These 250 nm diameter blue fluorescent-emitting microparticles are manufactured from polylactide*, a biodegradable, thermoplastic, aliphatic polyester derived from renewable resources such as corn starch or sugarcane. Recent research has shown promise in the use of these microparticles for drug transport and delivery and for enhancing the immune response when combined with antigen.

Biodegradable microparticles are stable at neutral pH for at least three months. Degradation can be triggered by exposing the particles to a basic or acidic pH or by enzymatic hydrolysis.

More Information

*Polylactide is also known as poly(D,L-lactic acid) or polylactic acid
