Abstract
The present invention provides a solvent-free viscoelastic RSF liquid by modifying the RSF surface with polyethylenimine and polyethylene glycol-based polymer surfactant, which surrounds each RSF molecule by forming a dual shell and thereby minimizes the inter RSF interactions and thus prevents formation of β-sheet aggregation. The engineering of RSF surface with PEI and PS significantly improved the conformational stability and storage time of RSF liquid compared to native RSF as silk I conformation of RSF liquid remained intact for more than 8 months.
