Chirality from <scp>d</scp>-guanosine to <scp>l</scp>-guanosine shapes a stable gel for three-dimensional cell culture

Abstract

It is proved that L-guanosine (L-G) as an enantiomer of D-guanosine (D-G) forms more stable gels than D-G, suggesting that alteration of chirality may be a new strategy for improving the lifetime stability of supramolecular hydrogels. Experiments for three-dimensional cell culture reveal that the L-G gel is a candidate for the extracellular matrix.
