摘要
Three new hydrogelators based on the conjugates of three naturally occurring biological building blocks:nu-cleobase,saccharide,and amino acids,were explored.Being synthesized via a facile solid phase peptide synthesis route,the hydrogelators self-assemble in water to afford supramolecular nanofibers and hydrogels.Transmission electron microscopy,oscillation rheometry,and circular dichroism reveal that the hydrogels consist of largely he-lix-based nanofibers of the widths of 5-12 nm and exhibit storage moduli up to 1 kPa.These hydrogelators also exhibit excellent cell-compatibility.This work illustrates a new platform for constructing molecular soft materials for nanobiotechnology.
