Luna Nanotech’s PLGA-PEG nanoparticles are engineered with a PEGylated surface featuring terminal azide groups, making them highly versatile for bioconjugation using click chemistry. These nanoparticles are synthesized using a proprietary method that ensures a narrow size distribution and exceptional batch-to-batch reproducibility. This precise control over particle characteristics is crucial for consistent experimental results and reliable therapeutic outcomes.

The core of these nanoparticles is composed of PLGA, a well-established biocompatible and biodegradable polymer. This makes them an excellent choice for various biomedical applications where controlled release and safe degradation are paramount. The incorporation of PEG (polyethylene glycol) on the surface provides several advantages, including reduced non-specific protein adsorption, prolonged circulation time in vivo, and enhanced stability in biological fluids. The terminal azide groups on the PEG chains enable facile conjugation of a wide range of biomolecules, such as antibodies, peptides, and nucleic acids, via copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC).

Established applications of this technology include:

• Drug Delivery: Encapsulation and targeted delivery of small molecules, proteins, and nucleic acids for various therapeutic purposes, including cancer therapy and anti-inflammatory treatments.
• Gene Therapy: Efficient delivery of genetic material (e.g., DNA, RNA, siRNA) into target cells, offering potential for treating genetic disorders and developing novel vaccines.
• Vaccine Delivery: Development of advanced vaccine formulations that enhance antigen presentation and stimulate robust immune responses, leading to improved efficacy.

Each batch of PLGA-PEG Azide nanoparticles undergoes rigorous quality control, including dynamic light scattering (DLS) for size and polydispersity index (PDI) determination, and ninhydrin assay for quantifying the amine concentration on the nanoparticle surface. This commitment to quality ensures researchers receive consistent and reliable materials for their demanding applications.
