Web24 Dec 2024 · The results show that L-KYN is an efficient scavenger of OH and ONOO-, but not O 2 -or H 2 O 2 and that it prevents DNA and protein oxidative degradation in synthetic systems. L-KYN diminishes the oxidative effect induced by FeSO 4 on brain homogenates at lower concentrations (1 µM) when compared to KYNA (100 µM). Furthermore, the sub … Web30 Sep 2024 · Here, we present a molecularly imprinted two dimensional (2D) Photonic crystal (PC) hydrogel sensor for the detection of L-KYN in human serum. The sensor utilizes polystyrene-based 2D PC colloidal arrays (2D PCCA) hydrogel with methacrylic acid as the functional monomer which can imprint the L-KYN template by hydrogen bonding. After …
