Research progress on single-molecule array technology-based blood neuronal markers for Alzheimer's disease / 中华老年医学杂志

Early detection and intervention is an important strategy for the prevention and treatment of Alzheimer's disease(AD). Blood screening for AD has advantages such as low cost and convenient sample collection.However, there are also problems such as low levels of markers in peripheral blood and insufficient sensitivity of detection methods.At present, as a highly sensitive detection technology for protein molecules, single-molecule array(Simoa)technology can accurately analyze low-concentration biomarkers that cannot be detected by traditional methods.This article reviews research progress on blood neuronal markers for early AD diagnosis based on the new Simoa technology.
