Ferritinnels

Ferritinnels, also known as ferritin nanoparticles, are synthetic nanoparticles composed of ferritin protein shells encapsulating various inorganic cores. Ferritin is a ubiquitous protein found in the cytoplasm of cells, primarily responsible for the storage and release of iron. The protein shell of ferritin is composed of 24 subunits, arranged in a spherical structure with an internal cavity that can accommodate iron ions or other inorganic materials.

Ferritinnels are typically synthesized through a process involving the self-assembly of ferritin protein subunits around a specific inorganic core. The choice of core material can vary widely, including metals like gold, silver, or iron oxide, as well as semiconductors such as cadmium selenide or quantum dots. The resulting nanoparticles exhibit unique physical and chemical properties, influenced by both the protein shell and the encapsulated core.

One of the key advantages of ferritinnels is their biocompatibility and biodegradability. The ferritin protein shell is naturally recognized and processed by the body, making these nanoparticles suitable for biomedical applications. They have been explored for use in drug delivery, imaging, and as contrast agents in magnetic resonance imaging (MRI). Additionally, ferritinnels can be functionalized with various molecules, allowing for targeted delivery to specific cells or tissues.

Research on ferritinnels is ongoing, with efforts focused on optimizing their synthesis, enhancing their stability, and expanding their range of applications. As our understanding of these nanoparticles grows, they hold promise for advancing various fields, including medicine, materials science, and environmental remediation.
