Their biocompatibility and versatility make them valuable across diverse sectors, including those growing rapidly in India's industrial landscape.

How do PEG derivatives enhance solubility and stability of molecules? ▼

PEG derivatives enhance solubility due to the hydrophilic nature of the PEG chain, which allows molecules to disperse more readily in aqueous solutions. For stability, the bulky PEG chain creates a 'steric shield' around the attached molecule, protecting it from aggregation, enzymatic degradation, and interactions with the immune system. This makes the modified molecule more stable and extends its functional lifespan, a critical factor for sensitive biomolecules.

Are PEG derivatives safe for use in biological systems? ▼

Generally, PEG and its derivatives are considered safe and biocompatible, which is why they are widely used in medical and pharmaceutical applications. They are non-toxic, non-immunogenic, and readily excreted from the body.
