WebHistidine is one of the essential amino acids in the human body, and the variation of its concentration in vivo has shown it to align with some liver and kidney diseases. In this work, a series of novel poly(2-oxazoline) derivatives bearing chiral pyrrolidine–triazole moieties in the side chain were designed and synthesized to serve as chemical sensors for histidine. Poly-histidine tags (of six or more consecutive H residues) are utilized for protein purification by binding to columns with nickel or cobalt, with micromolar affinity.
