Fe-doped MoS2 nanomaterials with amplified peroxidase mimetic activity for the colorimetric detection of glutathione in human serum

Molybdenum Disulfide-Based Nanoprobes: Preparation and Sensing Application

“…The binding molecule needs to be modified, few choices of binding molecules [28,29] noble metal nanoparticles -mediated simple, facile, stable, wide variety of binding molecules, properties enhanced complicated preparation process [30][31][32][33][34][35][36]…”

“…Moreover, this colorimetric sensor can determine cysteine in medical tables. Similarly, Singh et al utilized the highly-efficient peroxidase-like activity of Fe-doped MoS 2 nanomaterials to colorimetricly detect glutathione in buffer and human serum [ 34 ]. The satisfactory results further proved the excellent application of MoS 2 -based nanoprobes in the colorimetric sensing field.…”

Novel Thermal Decomposition Method for the Synthesis of Iron‐doped SnS2 Nanoparticles and Studies on their Peroxidase‐like Activity

“…[28] Singh et al have synthesized Fe doped MoS 2 nanoparticles using hydrothermal method and employed them as catalyst for peroxidaselike activity and as colorimetric sensor for the determination of glutathione in human serum. [29] The synthesis of Co doped CuSmontmorillonite nanocomposites has been reported by Wu et al [30] The synthesized nancomposites were used for peroxidase-like activity and colorimetric detection of H 2 O 2 . Zhang et al have synthesized Ce(III) doped MoS 2 nanosheets using hydrothermal method and employed them as catalyst for peroxidase-like activity and colorimetric sensing of H 2 O 2 .…”

Fe-Doped polydopamine nanoparticles with peroxidase-mimicking activity for the detection of hypoxanthine related to meat freshness

“…28–31 Nanoenzymes with peroxidase-mimetic activity have excellent properties that greatly refine the environmental intolerance and high cost of natural enzymes such as horseradish peroxidase (HRP), making them a strong competitor and potential alternative to natural enzymes. 32,33 Besides, the nanozyme with peroxidase-mimicking activity could effectively catalyze H 2 O 2 to generate hydroxyl radicals (•OH) under acidic conditions and further oxidize colorless 3,3′,5,5′-tetramethylbenzidine (TMB) to blue oxTMB with absorbance at 653 nm, that the principle could be well applied to colorimetric detection. From the above point of view, Fe-doped polydopamine (Fe-PDA) nanoparticles synthesized using a high-temperature hydrothermal method were adopted as an effective nanozyme for the detection of Hx, realizing visual analysis by high color contrast of color rendering substrate (TMB).…”
