How are Stealth Features Achieved?

Stealth features can be achieved through various methods, including:
1. Surface Modification: Coating nanoparticles with polymers like PEGylation (Polyethylene Glycol) can help them evade the immune system.
2. Shape and Size Control: Optimizing the shape and size of nanoparticles can minimize immune recognition and enhance circulation time.
3. Biomimetic Strategies: Using natural cell membranes or proteins to cloak nanoparticles, making them appear as 'self' to the immune system.
4. Advanced Materials: Employing materials like metamaterials that can manipulate electromagnetic waves, aiding in stealth for military applications.
