    摘要: There is provided a novel method for amplifying mass spectrometric signals. More particularly, a novel method for detecting signals of a target molecule includes: i) allowing a test sample, in which it is required to determine whether or not a target molecule is present, to be contact with a gold particle whose surface is modified to selectively bind to the target molecule, ii) allowing a low molecular molecule engrafted to the gold particle to generate mass spectrometric signals after the interaction, such as binding, between the gold particle and the target molecule, and iii) amplifying the mass spectrometric signals by generating a great deal of mass spectrometric signals of the low molecular molecule even in the presence of a trace of the target molecule. Also, the assay system using the method and the gold particle prepared in the method are provided. The method may be useful to specifically amplify signals of the target molecule without any pretreatment of a test sample, which makes it possible to measure the target molecule simply and precisely.

    摘要: Provided is a novel method for amplifying mass spectrometric signals. A novel method for detecting signals of a target molecule includes: allowing a sample, which comprises a target molecule, to contact a gold particle having a surface modified to selectively bind the target molecule, allowing a low molecular weight molecule engrafted to the gold particle generate mass spectrometric signals after the interaction, e.g., binding, between the gold particle and the target molecule, and amplifying the mass spectrometric signals to generate much mass spectrometric signals of the low molecular weight molecule even when trace amounts of the target molecule are present. An assay system using the method and the gold particle prepared in the method are provided. The method amplifies signals of the target molecule without pretreatment of a sample, making it possible to measure the target molecule simply and precisely.
