Background:

Protein nanoparticles offer potential for biomedical applications.
Developing stable and biocompatible nanocarriers is crucial for drug delivery and imaging.
Controlling nanoparticle size, charge, and structure is essential for functionality.

Purpose of the Study:

To report a novel type of protein nanoparticle with a unique lipid-protein structure.
To demonstrate the modular synthesis and controlled properties of these nanoparticles.
To evaluate their suitability for cell imaging and drug delivery.

Main Methods:

Synthesis of protein nanoparticles with a covalently attached and a physically assembled lipid layer.
Characterization using circular dichroism and biophysical techniques (purity, size, charge).
Assessment of thermal stability, fluorescence properties, protease digestibility, and biocompatibility.

Main Results:

Novel protein nanoparticles (11 nm) with a core-shell structure were synthesized.
Particle size and charge were predictably controlled during modular synthesis.
Protein secondary structure was retained; nanoparticles exhibited high thermal stability.
Fluorescently labeled nanoparticles showed strong, size-independent fluorescence.
Nanoparticles were water-soluble, non-toxic, biodegradable, and protease-digestible.

Conclusions:

The developed protein nanoparticles are highly stable, biocompatible, and biodegradable.
Their tunable properties and fluorescence make them promising for cell imaging.
Their characteristics are suitable for advanced drug delivery systems.
