Genetically Engineered Nanobody–Recombinant Antibody Colloidal Gold Strip for Ultrasensitive Atrazine Detection in Fruits and Vegetables

Food Safety and Health, EarlyView.
A sensitive colloidal gold immunochromatographic assay for atrazine was successfully established using genetically engineered nanobody‐recombinant antibody, which overcame the shortcomings of traditional antigen‐antibody. ABSTRACT Colloidal gold immunochromatography (CG‐ICA) is distinguished by its cost‐effectiveness and rapid detection capabilities ...

Matrix Metalloproteinases in Periodontal and Peri‐Implant Diseases: Contribution to Their Pathogenesis, Diagnosis, and Treatment

Journal of Periodontal Research, EarlyView.
This graphical abstract illustrates the role of matrix metalloproteinases (MMPs) across the pathogenesis, diagnosis, and therapeutics of periodontal and peri‐implant diseases. Microbial and host stimuli trigger MMP activation leading to extracellular matrix breakdown, point‐of‐care aMMP‐8 detection aids diagnosis, and adjunctive or AI‐assisted ...
