ABSTRACT
In the face of complex public health emergencies and various social medical needs in new situations, it is urgent to establish rapid detection technology for the early detection of pathogens to control their spread and minimize the resultant health and societal impact. Point-of-care testing (POCT) that allows rapid, on-site, and affordable detection and monitoring of health conditions at home or away from clinical labs has received increasing attention in modern medicine. In this work, we have synthesized multifunctional magainin I-human chorionic gonadotropin (hCG)-Cu3(PO4)2 nanoflowers and demonstrated a new strategy for the fast diagnosis of pathogenic microorganisms by combining functional nanoflowers with a lateral flow immunoassay device. The prepared multifunctional nanoflowers immobilized many signal molecules, which solves the poor sensitivity of traditional lateral flow strips and realizes the highly sensitive detection of pathogenic microorganisms ("accurate detection"). Besides, this method can complete the rapid transformation of commercial-off-the-shelf lateral flow strips and realize the fast diagnosis of target analytes in case of an outbreak ("fast detection"). Therefore, the established rapid and highly sensitive lateral flow immunoassay for the detection of pathogenic microorganisms will effectively improve the early diagnosis efficiency of infectious diseases caused by pathogenic microorganisms and shorten the diagnosis time of diseases.
