The Role of Cyclic Diketopiperazine in the Formation of Polypeptides on Silica Surfaces

open access: yesChemPlusChem, Volume 91, Issue 7, July 2026.
The parameters governing diketopiperazine (DKP) deposition, reactivity, and opening on amorphous silica are investigated through complementary studies in both liquid and gas phases in the frame of glycine (Gly) polymerization. The results demonstrate that DKP acts as an efficient intermediate toward the formation of linear poly‐Gly, yielding ...
