The present invention relates to an improved antibody specifically binding to amyloid-β oligomers (AβOs). Specifically, the present invention relates to an improved form of the antibody W20. Compared with the antibody W20, the improved form of the antibody W20 has a significantly improved affinity to AβOs, and can more significantly inhibit the aggregation of Aβ and the AβOs-induced toxicity of nerve cells, more effectively improve the cognition and memory functions of an Alzheimer's disease model mouse, and reduce pathological changes in the brain of the mouse. The improved form of the antibody can specifically bind to oligomers of an amyloid-β, α-synuclein, mHTT and SOD 1, can inhibit the aggregation and cytotoxicity of various amyloids, and has a better potential for treating various amyloid diseases, such as Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, than the antibody W20. The improved form of the antibody can specifically bind to a highly toxic amyloid protein oligomer Aβo*3F, and has a better AD diagnosis value. The amino acid sequence of the antibody W20 is as shown in SEQ ID NO: 1.

A use of a new highly toxic amyloid oligomer Apo*3F as a target for diagnosing Alzheimer's disease (AD) in the early stage and the middle-late stage and mild cognitive impairment (MCI) caused by AD. The Aβo*3F specifically binds to an antibody 3F and is present in cerebrospinal fluid (CSF), blood and/or brain tissue of AD patients and patients with MCI caused by AD, and the levels show highly significant differences in CSF, blood and/or brain tissue of AD patients, MCI patients and healthy elderly persons. In addition, the Apo*3F is an ultra-highly toxic oligomer, is the most important toxic component in an Aβ oligomer mixture, has a strong pathogenic effect, and plays a key role in the occurrence and development of AD.

The present disclosure relates generally to a sensor chip and methods for the detection of an analyte. In particular, the disclosure relates to a sensor chip for detecting an analyte in a subject suffering from a neurodegenerative disease. The sensor chip comprises a conductive layer on a membrane support layer, wherein a plurality of apertures extend through the conductive layer and the membrane support layer and are arranged such that illumination of the conductive layer and/or the membrane support layer produces a surface plasmon resonance.
