The recent development of nanozymes for food quality and safety detection

Abstract

As potential mimics of natural enzymes, nanozymes overcome many disadvantages of natural enzymes such as complex preparation and purification process, high price, poor stability and low recycling efficiency. Combined with...

Research progress on detection techniques for point-of-care testing of foodborne pathogens

“…Enzyme-linked immunosorbent assay (ELISA) is a sensitive and specific analytical biochemical method that can be used for the detection and quantitative or qualitative analysis of analytes without requiring sophisticated or expensive equipment ( Ferone et al, 2020 ; Nath et al, 2020 ; Rani et al, 2021 ; Kotsiri et al, 2022 ). At present, although traditional ELISA is widely used in scientific research and testing institutions and is the ideal method for the detection of viruses and antibodies ( Leva-Bueno et al, 2020 ; Navarro et al, 2020 ; Xiao et al, 2021 ), this traditional method is time-consuming and also requires skilled operation techniques and sophisticated instruments ( Luo et al, 2020a ; Razmi et al, 2020 ; Huang et al, 2022 ). So the researchers changed the traditional approach.…”

Nanozyme-based sensors for detection of food biomarkers: a review

“…32,34 So far, only a few articles have reviewed the data on nanozyme-based biosensors that aid food safety. 26,[35][36][37][38][39] Most of the review articles either provide an extensive discussion on the mechanisms of nanozyme-based biosensors 40 or provide an overview of the biosensing strategies available for detecting food contaminants. 41 For instance, Nguyen and Kim provided in-depth analyses of the nanomaterial-based colourimetric strategies to develop point-of-care devices for pathogen detection.…”

Experimentally designed chemometric models for the assay of toxic adulterants in turmeric powder

“…[19][20][21][22] Analytical reports provide authorities, food suppliers and consumers with the evidence necessary to build condence in food authenticity, safety and quality. 23 Analyzing pharmaceutical and food products is a highly multivariate process, as many factors (parameters) may be involved during the analysis. Powerful data collection and statistical tools are required to identify the factors that may affect the results of the experiment.…”
