• Creates osmotic pressure without ionic toxicity
• Chemically inert and biologically stable

^[1]

• Biocompatible
• Reduces cytotoxicity of cationic carriers
• Enhances circulation time
• Provides stealth effect against immune recognition

^[2]

• Induction of controlled osmotic (water-deficit) stress in plants
• Mimics drought-like conditions without introducing ions
• Comparative stressor against ionic stress (NaCl)

^[1]

• PEGylation of PEI to reduce toxicity
• Improves stability and biodistribution of nanoparticles
• Used in hybrid carriers (e.g., PEI-PEG-PCL)
