Electrospraying as a Technique for the Controlled Synthesis of Biocompatible PLGA@AgS and PLGA@AgS@SPION Nanocarriers with Drug Release Capability.

AgS nanoparticles are near-infrared (NIR) probes providing emission in a specific spectral range (~1200 nm), and superparamagnetic iron oxide nanoparticles (SPION) are colloidal systems able to respond to an external magnetic field. A disadvantage of AgS NPs is the attenuated luminescent properties are reduced in aqueous media and human fluids. Concerning SPION, the main drawback is the generation of undesirable clusters that reduce particle stability.
