We present a small molecule sensor that provides an optical response to the presence of an organophosphorus (OP)-containing nerve agent mimic. The design contains three key features: a primary alcohol, a tertiary amine in close proximity to the alcohol, and a fluorescent group used as the optical readout. In the sensor's rest state, the lone pair of electrons of the basic amine quenches the fluorescence
我们提出了一种小分子传感器,可对含有有机磷 (OP) 的神经毒剂模拟物的存在提供光学响应。该设计包含三个关键特征:伯醇、靠近醇的叔胺和用作光学读数的荧光基团。在传感器的静止状态下,碱性胺的孤对电子通过光诱导电子转移 (PET) 淬灭附近荧光团的荧光。暴露于 OP 神经毒剂模拟物会触发伯醇的磷酸化,然后随着胺取代产生的磷酸盐迅速发生分子内取代反应。这种环化反应生成的季铵盐不再具有孤对电子,

An object of the invention is to provide a method for enabling MSn (n>) analysis of a trace amount of a sample and easily and rapidly obtaining structural information by identifying a bonding position of the labeling compound in a molecule with the MSn (n>) analysis. According to the present invention, by labeling a particular moiety of the molecule in a stable manner, ions are easily generated and stabilized, thereby improving sensitivity of the MS. The amount of precursor ions generated in this manner is an amount enough to carry out the MSn (n>1) analysis and to generate structure-specific ions with high reproducibility. The structural information can be easily and rapidly obtained with high sensitivity.
本发明的目的是提供一种方法,以便能够对痕量样品进行 MSn (n>)分析,并通过 MSn (n>)分析确定标记化合物在分子中的键合位置,从而方便快捷地获得结构信息。根据本发明,通过以稳定的方式标记分子中的特定分子,离子很容易产生和稳定,从而提高 MS 的灵敏度。以这种方式产生的前体离子量足以进行 MSn(n>1)分析,并能以较高的重现性产生结构特异性离子。这样就可以轻松、快速、高灵敏度地获得结构信息。

The present invention provides a method for accurately discriminating between prostate carcinoma and benign prostatic hyperplasia based on a glycan structure of prostate specific antigen (PSA). The method of the present invention includes the steps of: purifying PSA from a sample derived from a subject; preparing a PSA derivative from the PSA; labeling the PSA derivative; and analyzing the labeled PSA derivative by the mass spectrometry method, in which the subject is identified as having prostate carcinoma when the ratio of the signal intensity of fucose-unbound glycan to the signal intensity of fucose-bound glycan in the labeled PSA derivative is greater than 1.0, and identified as having benign prostatic hyperplasia when the ratio is 1.0 or less.

In order to selectively detect a target substance in high sensitivity, a semiconductor sensor includes a substrate, a first electrode, a second electrode, and a semiconductor layer located between the first electrode and the second electrode, in which the semiconductor layer includes a semiconducting component and a substructure of immunoglobulin, and the substructure of immunoglobulin is bonded or attached to the semiconducting component through a linking group L1 in a hinge region of a heavy chain. Moreover, a method for producing a semiconductor sensor includes a step of forming the semiconductor layer, the step including a step of applying a semiconducting component between the first electrode and the second electrode.
