Recent advances in the applications of nanozymes for the efficient detection/removal of organic pollutants: a review

“…Common organic pollutants, such as pesticides, antibiotics, dyes, and phenolic compounds, can be detected via colorimetric methods. 103,104 By introducing chromogenic substrates in the reaction system during the catalytic oxidation process by nanozymes, organic pollutants can be detected sensitively and quickly. For example, Tang's group prepared boron nitride quantum dot-anchored porous CeO 2 nanorods (BNQDs/CeO 2 ) as a novel peroxidase-like nanozyme and utilized a nanozyme-aptamer system for the colorimetric detection of kanamycin (KAN).…”

Recent advances in colorimetric sensors based on nanozymes with peroxidase-like activity

“…128 In Fe 3 O 4 -CuO-CB [6]-GO nanozymes, CB [6] as a specific binding pocket equipped nanozymes with molecular recognition ability, and the synergistic effect of Fe 3 O 4 -CuO-GO [6]-GO nanozymes, a sensitive and selective colorimetric approach was thereby established for the detection of Hcy, with a LOD of 1.8 μM. In addition, other GO-based nanozymes, such as Prussian blue (PB), 129 cetyltrimethylammonium bromide (CTAB), 130 ganoderma polysaccharide (GP), 131 and quantum dot (QD) 132 incorporated GO also possessed the excellent properties of simulating peroxidase with higher catalytic activity. Accordingly, the ultrasensitive colorimetric biosensor was established for the detection of apolipoprotein A1 (ApoA1), amphetamine (AMP), methamphetamine (MAMP), L-cysteine (L-Cys) and H 2 O 2 , respectively.…”

Portable testing techniques for the analysis of drug materials

“…Numerous receptors have been employed in the optical detection of illicit drugs, from MIP functionalized quantum dots for the selective detection of methamphetamine (Masteri-Farahani et al, 2020) and cocaine (Chantada-V azquez T A B L E 2 Receptors and transduction events that have been employed in the fabrication of (bio)sensors for illicit drug analysis , 2018), to a modified gold nanoparticle aptasensor for the rapid detection of amphetamine-type stimulants (Adegoke et al, 2020), and chromium metal-organic framework nanoparticles for the highly sensitive detection of morphine (Alhaddad & Sheta, 2020).…”
