et al.

Abstract: The rational design of nanozymes with excellent enzymelike catalytic activity and high stability has been a promising objective for biochemistry. Total antioxidant capacity (TAC) is a vital indicator of oxidative stress in humans. Herein, a smartphone-based visual sensing platform utilizing nanorod-shaped Ni−Fe-based metal−organic frameworks (Ni−Fe-MOFs) as peroxidase-mimic nanozymes was developed for the fast, portable, low-cost, and on-site determination of ascorbic acid (AA). The nanorod-shaped Ni−Fe-MOFs a… Show more
