Please help me to polish this technical paper to make it read more smooth and reasonable Chiral KL-D-Pox and SiQDs-KL-D-Pox were prepared by employing L-D-Phe as the precursor for pheomelanin and for

Chiral (K/L-/D-P)ox and SiQDs-(K/L-/D-P)ox were prepared using L-/D-Phe as the precursor for pheomelanin, while SiQDs-(K/L-/D-P)ox was synthesized through a mild one-pot aqueous process at room temperature (Scheme 1). To form nanofibrous gels, tripeptide Lys-Tyr-Phe (KYF) was used as a supramolecular precursor, which self-assembled into a translucent hydrogel consisting of a physically entangled network of nanofibrils at physiological pH in aqueous buffer. The KYF gel was then oxidized using mushroom tyrosinase, resulting in (KYF)ox and a red-brown color appearing within minutes. The oxidation of the pre-assembled peptide does not lead to the formation of 5,6-dihydroxyindole intermediates as the tyrosine amine is already occupied in a peptide bond, but rather to the formation of catechol and quinone side chains that can further polymerize. After 24 hours, a colloidal film forms at the oxygen-rich air/liquid interface, and the suspension matures.

To increase the fluorescence intensity, (K/L-/D-P)ox was modified using 1, 4-butane sultone. As shown in Figure S1, the fluorescence intensity of (K/L-/D-P)ox increased by 1.5 times higher after the addition of 1, 4-butane sultone. The melanin-like SiQDs (SiQDs-(K/L-/D-P)ox) with wider emission wavelength were synthesized using DAMO as the silicon source through a hydrothermal method. The specific reaction mechanism is shown in Figure S2.
