Chemical Exchange Saturation Transfer (CEST) is a novel MRI contrast mechanism for detection of water exchangeable protons. We have designed peptides which form hydrogels suitable for use as adjuvants in cell therapy. These peptides are designed to form strong hydrogen bonding networks in order to slow down imino proton chemical exchange. These peptide-based hydrogels possess a wide range of unique properties that make them potentially applicable for different biological studies.
