“…The third route is based on enzyme-like NP-catalyzed substrate reactions [37][38][39][40][41][42][43][44]. Enzyme reactions have been widely used for the visual detection of bacteria; however, they have limited advantages due to their low stability and the high cost of enzymes.…”

“…The catalytic activity of some nanomaterials is similar to that of enzymes, which triggers a catalytic reaction that induces a color change in the chromogen [38,40,96]. These enzyme-like materials include Fe 3 O 4 , metallic oxide NPs (Co 3 O 4 and CeO 2 ), noble metal NPs (AuNPs, Ag/PtNPs, and Au/PdNPs), and carbon-based nanomaterials (e.g., graphene oxide (GO)) [26,[37][38][39][97][98][99][100][101]. A ZnFe 2 O 4 -modified reduced GO (rGO) nanostructure with HRP-like activity was used to detect S. typhimurium (Figure 3A) [37].…”

“…This system had a detection limit of 0.51 CFU/mL with a linear range of 1.93 × 10 1 to 1.93 × 10 5 CFU/mL. Another peroxidase mimic, graphitic C 3 N 4 @Cu 2 O (g-C 3 N 4 @Cu 2 O), was used for the detection of S. typhimurium [39]. A S. typhimurium-specific aptamer was attached to C 3 N 4 @Cu 2 O, and the presence/absence of cells was monitored by detecting a color change.…”

Bacterial contamination is a public health concern worldwide causing enormous social and economic losses. For early diagnosis and adequate management to prevent or treat pathogen-related illnesses, extensive effort has been put into the development of pathogenic bacterial detection systems. Colorimetric sensing systems have attracted increasing attention due to their simple and single-site operation, rapid signal readout with the naked eye, ability to operate without external instruments, portability, compact design, and low cost. In this article, recent trends and advances in colorimetric systems for the detection and monitoring of bacterial contamination are reviewed. This article focuses on pathogen detection strategies and technologies based on reaction factors that affect the color change for visual readout. Reactions used in each strategy are introduced by dividing them into the following five categories: external pH change-induced pH indicator reactions, intracellular enzyme-catalyzed chromogenic reactions, enzyme-like nanoparticle (NP)-catalyzed substrate reactions, NP aggregation-based reactions, and NP accumulation-based reactions. Some recently developed colorimetric systems are introduced, and their challenges and strategies to improve the sensing performance are discussed.

“…Low cost, availability, and minimum response time are the advantages of this method. [30,31] Until now, a wide range of processing techniques has been introduced to construct μPADs by patterning hydrophilic/hydrophobic microstructures on paper substrates, including paper cutting, wax printing, inkjet printing, and photolithography. In this assay the peroxidaselike activity of CWNPs is analyzed in the presence of H 2 O 2 and TMB.…”

Abnormal glucose level can cause irreversible damage, including diabetes. In this work, a sensor was designed that mimics the peroxidase property of the natural horseradish peroxidase (HRP). The proposed sensor detects the presence of glucose through the reduction of hydrogen peroxide (H 2 O 2 ) and the oxidation of tetramethylbenzidine (TMB). This sensor shows linear behaviour in the range of 0.001-50 μM with a limit of detection down to 0.8 nM. In addition, a paper-based format of this sensing platform was performed which enables fast and sensitive detection and further reduces the expenses. In this method the linear behaviour of the sensor is between 0.005-40 μM and the detection limit is as low as 2.4 nM. The glucose detection in human saliva was also performed, showing an acceptable accuracy. Thus the sensor is practically suitable for the non-invasive detection of glucose.
