A newly developed technique could make it easier to measure very small concentrations of molecules, which may have implications in early diagnostic testing for Alzheimer’s and other diseases. The technique was described in Research, in the study “Single-Atom Nanozymes Linked Immunosorbent Assay for Sensitive Detection of Aβ 1-40: A Biomarker of Alzheimer’s Disease.” One of the most common techniques used in biomedical laboratories is the enzyme-linked immunosorbent assay (ELISA). The test allows researchers to measure the…
