As shown in FIG. 3, the invention provides a sensor, which comprises a substrate and a metal resonator array arranged on the substrate and composed of a plurality of sensor units. In one embodiment, the substrate is high-resistance silicon.
As shown in fig. 1 and 2, the present invention provides a system for rapidly measuring the thermal denaturation temperature of protein, comprising the sensor of claim 2, a heat conducting plate 3 and a heating plate 4, wherein the sensor is arranged on the heat conducting plate, the heat conducting plate is connected to the heating plate, a circular hole is arranged on the heat conducting plate, and the sensor is arranged in the circular hole.
As shown in fig. 7, the present invention also provides a method for rapidly measuring the thermal properties of a protein, comprising the steps of:
protein solutions with different concentrations are prepared by taking a protein sample to be detected with the size of 5 mu m and 30 mu m deionized water. (to verify that the denaturation temperature of the protein is independent of concentration and only dependent on temperature.)
Using a pipette to drop 5 mul of prepared protein solution with different concentrations on the surface of the sensor, drying the sensor on a heating table at 30 ℃ until a layer of film 1 is formed, repeatedly overlapping the film on the desired concentration to be measured, and drying the film on the heating table at 30 ℃.
A metal strip with good heat conduction and a round hole is connected with the heating table, the sensor 2 is fixed on the round hole 5 and is positioned on a focal plane of the terahertz waves, so that the center of the round hole coincides with the center of the focal plane of the terahertz waves, and the terahertz waves vertically pass through the sensor.
And when the relative humidity of the air of the terahertz system is reduced to below 1%, starting a temperature control heater to heat the sample wafer. And measuring the terahertz spectrum penetrating through the sample wafer in the heating process, and mainly observing and recording the position change condition of the resonance absorption peak.
From the real-time measurement of the terahertz spectrum during the temperature rise, it was found that the position of the resonance absorption peak was almost unchanged before the thermal denaturation of the protein occurred. When thermal denaturation occurs, the position of the resonance absorption peak of the sensor jumps to high frequency, and the change value is larger than 5 GHz. Therefore, the corresponding heater temperature when the resonance absorption peak position of the sensor jumps to high frequency is the thermal denaturation temperature of the protein. The theoretical basis of this measurement method is: after the protein is denatured, the protein conformation changes, thereby causing the dielectric constant to change, and the sensor of the invention is sensitive to the change of the dielectric constant.
The invention relates to a method and a system for rapidly detecting protein thermal denaturation temperature by utilizing a metamaterial sensor and a terahertz spectrum. The sensor is formed by combining a U-shaped resonator and an H-shaped resonator surrounded by the U-shaped resonator, the sensor has a strong resonance absorption peak in a terahertz frequency band, when a layer of substance covers the surface of the sensor, the absorption peak can move to a low frequency, and the magnitude of frequency shift is closely related to the concentration of the surface substance and the dielectric property of the surface substance. When measuring the temperature of protein thermal denaturation, firstly, a trace amount of protein solution is dripped on the surface of a sensor and dried to form a layer of protein film. And then, putting the sensor into a terahertz spectrum system, heating through a heating plate, and carrying out terahertz spectrum acquisition. When the temperature does not reach the thermal denaturation temperature of the protein, the resonance peak position hardly changes. When the temperature reaches the protein thermal denaturation temperature, the resonance peak frequency jumps to high frequency, and the temperature corresponding to the resonance peak frequency jump is the protein denaturation temperature. The method for measuring the protein thermal denaturation temperature through resonance peak position jumping has the advantages of high accuracy, simple operation and high detection speed, and is particularly suitable for application occasions with high requirements on accuracy and instantaneity.
