[0035] In one embodiment, referring to FIG. 1, FIG. 1 shows one of the structural schematic diagrams of the detection chip 100 in the present application. The detection chip 100 in the present embodiment includes a master control module 110 and a plurality of detection modules 120 (n detection modules 120 are shown in FIG. 1, n is a positive integer); the master control module 110 is connected with the plurality of detection modules 120, used for connecting a terminal 200 to receive a detection instruction from the terminal 200, and under the action of the detection instruction, providing at least one gear detection voltage to the plurality of detection modules 120; each detection module 120 detects a biological marker under the driving action of the target gear detection voltage to output a detection signal; the biological markers detected by each detection module 120 are not completely the same, and the target gear of the detection voltage received by each detection module 120 corresponds to the biological marker; the master control module 110 is also used for transmitting the detection signal to the terminal 200.
[0036] The main control module 110 refers to a computer chip with signal transmission and signal processing functions, and can be an MCU (Microcontroller Unit). The main control module 110 in the embodiment can form a signal transmission channel with the terminal 200 and the plurality of detection modules 120, respectively, for receiving a detection instruction of the terminal 200, and controlling the plurality of detection modules 120 to detect the biomarker according to the detection instruction, respectively or simultaneously. Specifically, the main control module 110 can provide a detection voltage of a target gear to each detection module 120, and the detection voltage of the target gear corresponds to the biomarker, so that the biomarker can be accurately and efficiently detected. In addition, the main control module 110 can also collect detection signals of the plurality of detection modules 120 in real time, and transmit the detection signals to the terminal 200 after conversion, amplification, filtering and other processing, so that the terminal 200 can analyze the received detection signals to obtain a corresponding detection result.
[0037] It can be understood that the detection voltages of different gears are different in size, and the type of the biomarker to be detected can be determined. In actual application, the user can input a detection instruction including biomarker type information to be detected to the main control module 110 through the terminal 200, so that the main control module 110 provides a detection voltage of a corresponding gear (i.e., a target gear) to the corresponding detection module 120 according to a preset control logic, and realizes detection of the biomarker to be detected. In addition, the terminal 200 can also prestore the corresponding relationship between the detection voltage of the target gear and the biomarker type. When the user inputs the biomarker type to be detected, the terminal 200 can transmit the detection voltage of the corresponding target gear as a detection instruction (i.e., the information carried by the detection instruction is the detection voltage of the target gear) to the main control module 110 based on the biomarker type to be detected, so that the main control module 110 provides a detection voltage of a corresponding gear (i.e., a target gear) to the corresponding detection module 120, and realizes detection of the biomarker to be detected.
[0038] The plurality of detection modules 120 can work independently or cooperatively, and the main control module 110 can provide a target gear detection voltage for each sensing channel. Each detection module 120 can be any detection chip 100 or sensor capable of detecting biomarkers. Taking the integrated sensor as an example, the detection module 120 can be a field effect transistor sensor. The field effect transistor sensor has a gate electrode with a biomolecular probe. The biomolecular probe is used for specific binding with a target detection substance in the biomarker, so that the field effect transistor sensor outputs a detection signal under the driving action of the target gear detection voltage. In addition, the field effect transistor sensor has a substrate, a channel layer on the substrate, a semiconductor layer on the channel layer, source and drain electrodes at both ends of the layer, a high dielectric constant dielectric layer on the semiconductor layer, and a gate electrode above the layer. The surface of the gate electrode is modified with a fixed biomolecular probe. When the biomarker to be detected contacts the biomolecular probe, the biomarker is detected by detecting the current change of the field effect transistor. Since the main control module 110 can also integrate a signal processing circuit, it can amplify, filter and digitize the detection signal from the field effect transistor, ensuring high sensitivity and high resolution of the signal. In addition, the detection chip 100 in the embodiment can also use advanced packaging metal to protect the detection modules 120 inside the detection chip 100, ensuring its long-term stability and reliability. The packaging material can be a material with good chemical stability.
[0039] In addition, the biomarker to be detected includes nucleic acid biomarkers of viruses, bacteria, fungi, chlamydia, antibodies, antigens, metabolic small molecules, ions, etc.
[0040] The detection chip 100 in the embodiment integrates a plurality of detection modules 120, which can control the plurality of detection modules 120 to drive the detection of biomarkers under the target gear detection voltage according to the detection instruction of the terminal 200, and can simultaneously detect a plurality of biomarkers, thereby improving the detection efficiency. That is, the detection chip 100 in the embodiment realizes the integration of molecular recognition, signal detection, signal analysis and signal transmission, realizes the simultaneous detection of multiple samples on the same chip, and provides a more efficient and reliable solution for multi-parameter detection. Compared with the current multi-parameter biological detection platform, the integration degree is higher, the portability is enhanced, and the detection application range is wider.
[0041] In one embodiment, referring to FIG. 2, FIG. 2 shows a structural schematic diagram of the master control module 110 in one embodiment of the present application (n detection modules 120 are shown in FIG. 2, n is a positive integer), the master control module 110 in this embodiment includes a driving unit 111, a sampling unit 112, a communication unit 113 and a control unit 114; the driving unit 111 is connected with the control unit 114 and the N detection modules 120 respectively; the sampling unit 112 is connected with the control unit 114 and the detection modules 120 respectively, for collecting detection signals and transmitting the detection signals to the control unit 114; the communication unit 113 is connected with the control unit 114, for communicating with the terminal 200 to transmit detection instructions to the control unit 114; the control unit 114 is used for controlling the driving unit 111 to output detection voltages of target gears to at least one of the detection modules 120 according to the detection instructions, and transmitting the detection signals to the communication unit 113, so that the communication unit 113 transmits the detection signals to the terminal 200.
[0042] The driving unit 111 can output detection voltages of target gears to the corresponding detection modules 120 under the control of the control unit 114, so as to drive the corresponding detection modules 120 to detect. The sampling unit 112 collects the detection signals of the detection modules 120, so that the control unit 114 can read the detection signals and transmit the detection signals to the terminal 200 through the communication unit 113. That is, the driving unit 111 can be any module, circuit or electronic device that can drive the detection modules 120 to work, and correspondingly, the sampling module can be any module, circuit or electronic device that can collect detection signals and convert the detection signals into a readable form for the control unit 114. The communication unit 113 can be a communication interface or a wireless communication component, that is, the control unit 114 and the terminal 200 can be connected by wired communication or wireless communication.
[0043] It should be noted that in other embodiments, the control unit 114 and the communication unit 113 can also be a control chip that is integrated, and are not necessarily two independent functional chips.
[0044] In this embodiment, the driving unit 111, the sampling unit 112, the communication unit 113 and the control unit 114 are used to realize independent control of each detection module 120 and processing and transmission of the detection signals, which can improve the detection efficiency of the detection chip 100 and the stability of signal transmission.

[0047] In one embodiment, the sampling unit includes an analog-to-digital converter for converting the detection signal in the form of a digital electrical signal into an analog electrical signal and transmitting the analog electrical signal to the control unit.
[0048] In the embodiment, the high-sampling-rate analog-to-digital converter is configured to realize high-precision detection of the measured signal, ensure capturing subtle changes in the signal, and enhance the sensitivity of the detection chip to weak current changes, thereby realizing high-sensitivity and high-precision detection, improving the overall detection performance and reliability, and being suitable for fine analysis of weak current signals, such as pathogen detection.
[0049] In one embodiment, the communication unit includes a serial communication component or a Bluetooth component. In the embodiment, the Bluetooth component is used to realize the communication connection between the detection chip and the terminal, and the user can interact with the detection chip through the terminal, thereby improving the application scenarios of the detection chip.
