Colloidal Au sphere and nanoflower-based immunochromatographic strips for sensitive detection of zearalenone in cereals

Abstract

Zearalenone (ZEN), also known as F-2 toxin, is a secondary metabolite in the toxic Fusarium species with estrogen properties. ZEN and its derivatives can cause developmental and reproductive disorders in...

High-performance colorimetric sensor based on PtRu bimetallic nanozyme for xanthine analysis

“…Nanozymes are nanoscale materials with inherent enzyme-mimicking activity, exhibiting both the structural properties of nanomaterials and catalytic functionalities of bio-enzymes ( Qiao et al, 2023 ; Zou et al, 2023 ). Despite the existence of numerous excellent materials, the development of nanozymes with the characteristics of high stability and robust catalytical performance of is still the focus and hotspot of current research ( Geng et al, 2024 ).…”

Rapid detection of multiple antibiotics in chicken samples via a fluorescence nanobiosensor coupled with a homemade fluorescence analyzer

“…The ICS assay generally works in qualitative or semiquantitative analysis in addition to single target detection from a single sample due to the substantial interference with food matrices and colored samples. [18][19][20] As complementary or alternative analytical techniques, biosensors which comprise a biological recognition element (such as an antibody, receptor, enzyme, etc.) and a transducer (converting the recognition event into a measurable signal) have elicited signicant interest in on-site detection of antibiotic residues in various matrices because of their superiorities of high sensitivity and selectivity, rapid detection, and easy operation.…”
