Smart Inulin-Based Polycationic Nanodevices for siRNA Delivery

Area of Science:

• Biomaterials Science
• Nanotechnology
• Gene Therapy

Background:

• Short interfering RNA (siRNA) offers therapeutic potential by silencing disease-related genes.
• Developing effective delivery systems for siRNA is crucial for its clinical application.
• Inulin, a biocompatible polysaccharide, is explored as a scaffold for nucleic acid-based drug delivery systems.

Purpose of the Study:

• To design and evaluate inulin-based nanodevices for siRNA delivery.
• To compare different inulin derivatives functionalized with oligoamines for their efficacy.
• To assess the chemical structure, biocompatibility, and gene silencing capabilities of these nanodevices.

Main Methods:

• Synthesis of inulin derivatives functionalized with oligoamines (e.g., EDA, DETA, SPM).
• Formation of polyplexes and polymeric coatings for nanocarriers.
• Characterization of nanodevices for structure, siRNA complexation, and biocompatibility.
• Evaluation of gene silencing efficacy in relevant models.

Main Results:

• Inulin-based nanodevices were successfully synthesized and characterized.
• Functionalized inulin demonstrated effective complexation with siRNA.
• The nanodevices exhibited good biocompatibility and potent gene silencing activity.
• Comparison revealed differences in performance based on chemical design and structure.

Conclusions:

• Inulin-based nanodevices represent a promising platform for siRNA delivery.
