    • The invention provides an SPR measuring method and a measuring system thereof. According to the measuring method, first, a linear-polarized coherent broadband pulsed light beam is incident onto a surface of a sample under detection of a SPR sensing device to cause reflection; next, a time-domain monotonous chirp is performed on the incident coherent broadband pulsed light and/or the SPR reflected light; finally, the time-domain monotonically chirped SPR reflected light beam is detected, and information of the SPR effect is obtained according to the detected signal. According to the invention, the spectrum detection method used in conventional slow wavelength interrogation is converted into the high-speed real-time detection of time-domain pulse shape signals. Thus, the procedure of the SPR reaction may be monitored closely, and dynamical curves with very high time resolution may be obtained, in that case, fast biochemical reaction procedures may be monitored. As each part of the measuring system may remain fixed during the measurement, a compact, miniature and portable system may be realized. The interrogation part of the sensing system is easy-to-realize, of low cost and compatible with various SPR devices and components.
    • 本发明提供一种SPR测量方法及其测量系统。 根据测量方法,首先,线性偏振相干宽带脉冲光束在SPR感测装置的检测下入射到样品的表面上以引起反射; 接下来,对入射相干宽带脉冲光和/或SPR反射光执行时域单调啁啾; 最后,检测到时域单调啁啾的SPR反射光束,并根据检测到的信号获得SPR效应的信息。 根据本发明,在常规慢波询问中使用的频谱检测方法被转换成时域脉冲形状信号的高速实时检测。 因此,可以密切监测SPR反应的过程,并且可以获得具有非常高的时间分辨率的动力学曲线,在这种情况下,可以监测快速的生化反应程序。 由于测量系统的每个部分在测量期间都可能保持固定,因此可以实现紧凑,微型和便携式系统。 传感系统的询问部分易于实现,成本低廉,与各种SPR设备和组件兼容。

    • The invention discloses a method for detection of genetically modified maize BT11. The principle of the method is that the DNA template of the sample is amplified at a temperature of 63° C.˜65° C. for 45˜60 min by using 4 specific primers and a DNA polymerase with strand displacement activity. The identification thereof is to make a judgment on whether BT11 component is contained in the sample by directly observing the turbidity in the reaction tube or the color change after the addition of SYBR Green with naked eyes or by agarose gel electrophoresis. The detection method of the invention has the advantages of high specificity, quickness, simplicity and convenience and the like, which provides a convenient method for detection of genetically modified maize BT11 with an extensive application prospect.
