These streptavidin magnetic nanoparticles come with the option to customize both magnetic properties and fluorescent labels. Our single-layer poly (lactic-co-glycolic acid) (PLGA) nanoparticles form nanostructures with a hydrophobic core encapsulated within a hydrophilic shell. The Streptavidin protein is covalently conjugated to the surface of the PLGA nanoparticles, providing a robust platform for bioconjugation. Dye molecules and magnetic nanoparticles are encapsulated within the hydrophobic core, providing both fluorescent and magnetic functionality.
The PLGA polymer is made with an FDA-approved biocompatible and biodegradable material. This versatile system allows for the easy loading of antibodies, proteins, and small molecules through the strong Streptavidin-Biotin interaction. It also offers a high degree of monodispersity and the option to be pulled down by an applied magnetic force.
This technology has three established applications:
- In vitro and in vivo delivery of proteins and small molecules: The nanoparticles serve as effective carriers, protecting therapeutic agents and facilitating targeted delivery.
- Magnetic cell pulldown and flow cytometry analysis: The magnetic property allows for the isolation of specific cells, while the fluorescent label enables detailed analysis.
- Dual fluorescence and MRI imaging: The combined fluorescent and magnetic properties allow for a powerful dual-mode imaging approach for both in vitro and in vivo studies.
