Title : Theranostic hyaluronan coated edta modified magnetic mesoporous silica nanoparticles for targeted delivery of cisplatin

Abstract:

One of the eminent capabilities of nanoparticles in drug delivery is active targeting. Mesoporous silica nanoparticles (MSNs) are among the well-known nanocarriers, which have been utilized for gene and drug deliveries due to their particular physical and chemical properties.  The present study aimed to introduce an engineered type of EDTA-modified Magnetic Mesoporous Silica Nanoparticles (MMSNs) with hyaluronan coating as a theranostic agent for the delivery of an anti-cancer drug (cisplatin). EDTA was first applied as a ligand for platinum-based drug loading. The nanoparticles were synthesized in several steps. The properties of each step were characterized by various techniques such as Fourier transform infrared (FT-IR), X-Ray diffraction (XRD), vibrating sample magnetometer (VSM), and N2 adsorption/desorption. Morphology was also checked by field emission scanning electron microscopy (FE-SEM) and Transmission electron microscopy (TEM). In addition, loading capacity (LC) and loading efficiency, and in vivo release of cisplatin were analyzed through ICP-OES. Eventually, the plasma concentration profile and cisplatin pharmacokinetics parameters after intravenous administration of EDTA-MMSN @ HA were evaluated. The average particle diameters of the prepared structure were an approximate range of 70-100 nm. The profile release of cisplatin in an acidic medium was faster in 72 hours, which confirmed the pH-responsive behavior of the nanoparticles. As the results of cytotoxicity showed, coating with HA can improve the internalization of nanoparticles in cancer cells compared to normal cells. Finally, EDTA-MMSN @ HA can be introduced as a new favor biocompatible and biodegradable nanoplatforms for targeted drug delivery which can improve pharmacokinetic parameters. Overall, this study successfully synthesized a novel multifunctional pH-responsive MSN for efficient drug delivery and magnetic resonance imaging.

Audience Take Away Notes:

  • Application of nanotechnology in the biopharmaceutical field
  • Summarize types of nanocarrier for smart drug delivery systems (DDSs)
  • Introduce mesoporous silica nanoparticles (MSN)as a novel structure in biomedical and bioimaging (THERANOSTIC agent)
  • Application of magnetic nanoparticles as contrast agents in Magnetic resonance imaging (MRI)
  • Advantages of MSN in comparison of other carriers include biocompatibility, high surface area, tunable morphology and pore size, porosity, and adjustable surface functional groups (active targeting).
