Novel drug delivery systems based on polymeric nanoparticles and microspheres as well as liposomes have demonstrated great potential in enhancing therapeutic effects of drugs. Biodegradable polymers with strong biocompatibilities such as poly(lactic-co-glycolic acid) (PLGA), polylactic acid (PLA), and polycaprolactone (PCL) have been widely used in developing particulate drug delivery systems. Active pharmaceutical ingredients (APIs), whether small molecules or biologic compounds, can be encapsulated into microspheres and nanoparticles or attached to a particle’s surface for specific drug delivery applications such as sustained release, targeted drug delivery, and protection of APIs from premature degradation. Upon administrating drug-loaded biodegradable nanoparticles and microparticles, the biocompatable polymer degrades in vivo by hydrolysis of the ester backbone into non-toxic products. The drug release rate can be modulated by selecting the right type of polymer and adjusting the encapsulation process.

RAFT (Reversible Addition-Fragmentation chain Transfer) is a form of living radical polymerization involving conventional free radical polymerization of a substituted monomer in the presence of a suitable chain transfer (RAFT) reagent.
Find reversible addition–fragmentation chain transfer(RAFT) polymerization process, classes of RAFT agents & applications.
Universal (Switchable) RAFT agents allow for the polymerization of both less activated and more activated monomers and are ideal for the synthesis of well-defined block copolymers.
Controlled radical polymerization, which provides exquisite tuning of macromolecular size, structure, composition and architecture, with experimental convenience, has become one of the most indispensable tools for polymer chemists.
The supply of low cost, high purity and effective Reversible addition−fragmentation chain-transfer (RAFT) Agents is the essential element in the industrial implementation of RAFT polymerization technology.

We offer Degradex® PLGA- and PCL-based plain and fluorescent microspheres and nanoparticles. Plain PLGA microspheres and PLGA nanoparticles can be used in drug and RNA delivery formulations as control agents or be used to test system compatibility before loading an API into the carrier. Fluorescent nanoparticles and microspheres can be used in numerous imaging and diagnostic applications such as:
Degradex® poly(lactic-co-glycolic acid) (PLGA) and polycaprolactone microspheres and nanoparticles are biodegradable and biocompatible polymeric particles that are available in a range of 100 nm to 50 μm in diameter. Degradex® particles can be used to confirm drug carrier compatibility prior to formulation development. In addition, surface functionalization of the particles with carboxyl groups enables Degradex® particles to be used for targeted therapy and increased circulation time.
Our fluorescent poly(lactic-co-glycolic acid) (PLGA) particles with excitation/emission wavelengths of 460/500, 530/582, 644/665 and 780/820 nm allow easy visualization of particles in bioimaging and diagnostic applications, including cell tracking, phagocytosis studies, fluorescent microscopy, and drug discovery. We offer green, orange, red and near-IR fluorescent PLGA particles in a range of sizes from 100 nm to 50 μm in diameter.
