P Addition

Addition of water triggers gelation in (poly)ethylene glycol (PEG) solutions of peptide gelators, with or without drugs added. The gels are formed by a combination of macromolecular crowding and hydrophobic effects as evident by significant secondary structure changes when compared to gel formed from pure water.
