[0039] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0040] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0041] Raman spectroscopy refers to the spectrum formed by the Raman scattering effect (the phenomenon that the frequency of light waves changes after being scattered) after the incident light is reflected by the sample to be tested. Raman spectroscopy can be used to analyze the vibration and rotation energy levels of the molecules in the sample to be tested. The Raman spectra of different molecules are different, so different molecules can be identified through Raman spectroscopy, which has a wide range of applications in the field of chemical analysis.

[0042] Surface Raman enhancement refers to the use of Raman spectroscopy to measure samples adsorbed on the rough surface of colloidal metal particles such as silver, gold or copper, which have low or no signal under traditional Raman spectroscopy. The surface Raman enhancement effect can achieve qualitative testing of more molecules and trace testing.

[0043] In related technologies, since the principle of the surface Raman enhancement effect is unknown, surface enhanced Raman spectroscopy analysis often relies on the experience and research reports of scientific researchers, and the analysis is often subjective.

[0044] In view of this, the present disclosure proposes a Raman spectroscopy testing method and system, a storage medium and an electronic device to solve the problems existing in the related art.

[0045] Figure 1 The flowchart of a Raman spectroscopy testing method according to an exemplary embodiment of the present disclosure is shown. The Raman spectroscopy testing method is applied to mobile terminals, such as mobile phones, tablets, wearable electronic devices, etc.

[0046] like Figure 1 As shown, the Raman spectroscopy testing method may include the following steps:

[0047] S11, receiving spectral data sent by a handheld Raman spectrometer.

[0048] The spectral data is obtained by dispersing the sample to be tested into an aqueous solution, dripping the aqueous solution onto a surface Raman enhanced spectroscopy (SERS) chip, and then performing a Raman spectroscopy test on the SERS chip dripping with the sample to be tested using the handheld Raman spectrometer.

[0049] The sample to be tested may be referred to as a substance to be tested, a molecule to be tested, etc., and the present disclosure does not limit this.

[0050] It should be explained that the surface Raman enhanced spectroscopy SERS chip refers to a chip used to obtain a spectrum using the surface-enhanced Raman scattering (SERS) effect. SERS uses conventional Raman spectroscopy to measure samples adsorbed on the surface of colloidal metal particles such as silver, gold or copper, or samples adsorbed on the rough surface of these metal sheets. The intensity of the Raman spectrum of the adsorbed sample can be increased by 10^3-10^6 times.

[0051] In one embodiment, after the sample to be tested is dispersed in an aqueous solution, the aqueous solution is dripped onto the SERS chip. The handheld Raman spectrometer performs a Raman spectrum test on the SERS chip to which the sample to be tested is dripped to obtain spectrum data. The handheld Raman spectrometer sends the collected spectrum data to a mobile terminal via a wired or wireless communication method.

[0052] This method has low detection cost and good repeatability. The consumables for different samples to be tested are only one SERS chip. Moreover, this portable Raman testing equipment can conveniently realize instant detection of samples to be tested and has strong adaptability to the environment.

[0053] S12, uploading the spectral data to a cloud database, so that the cloud database analyzes the spectral data to obtain a material analysis result of the sample to be tested.

[0054] The mobile terminal is in communication with a cloud database. The cloud database has data analysis capabilities. In some embodiments, the cloud database can be provided as a cloud server. In other embodiments, the cloud database represents a cloud server and a database.

[0055] S13, receiving the substance analysis result fed back by the cloud database.

[0056] In one implementation mode, the cloud database receives the spectral data uploaded by the mobile terminal, analyzes the spectral data, and obtains the material analysis result of the sample to be tested. The cloud database feeds back the material analysis result to the mobile terminal. The mobile terminal receives the material analysis result fed back by the cloud database.

[0057] In this way, the mobile terminal receives the spectral data sent by the handheld Raman spectrometer. The spectral data is obtained by dispersing the sample to be tested into an aqueous solution, dripping the aqueous solution onto the surface Raman enhanced spectroscopy SERS chip, and then performing a Raman spectral test on the SERS chip dripped with the sample to be tested by the handheld Raman spectrometer. The spectral data is uploaded to the cloud database for the cloud database to analyze the spectral data and obtain the material analysis results of the sample to be tested. The material analysis results fed back by the cloud database are received. Compared with the manual analysis method in the related art, the automatic analysis method disclosed in the present invention can avoid the influence of the subjectivity of manual analysis on the material analysis results. Therefore, the method disclosed in the present invention can improve the accuracy of the material analysis results.

[0058] Moreover, in this way, due to the short preparation cycle of the sample to be tested and the fast spectral test speed, the material analysis results can be quickly returned by relying on the cloud database. Therefore, this detection method is fast and convenient. In addition, this portable Raman test equipment uses surface Raman enhancement technology to greatly reduce the detection limit, and this method can achieve trace testing. Based on mobile terminals such as smart phones, Raman spectra can be processed in real time, and the accuracy of detection can be greatly improved by uploading spectral data to the cloud database for comparison.

[0059] Optionally, the Raman spectroscopy testing method further includes: displaying the material analysis result in text or voice broadcast.

[0060] By displaying the material analysis results to the user in text or voice broadcast, the user can be informed of the material analysis results of the sample to be tested in a timely manner without the user having to actively arrange time to query / obtain the material analysis results of the sample to be tested.

[0061] Optionally, the substance analysis result includes at least one molecular species.

[0062] In some embodiments, the cloud database analyzes the spectral data to obtain the material analysis result of the sample to be tested, which can be: comparing the spectral data with the reference spectral data of each molecular species to obtain target reference spectral data with a similarity greater than a threshold to the spectral data, and generating the material analysis result according to the target molecular species corresponding to the target reference spectral data.

[0063] The threshold is an empirical value set according to the requirements, and the present disclosure does not limit this. The reference spectrum data can be called standard spectrum data, and the present disclosure does not limit the name of the reference spectrum data.

[0064] The number of target reference spectrum data may be one or more, and accordingly, the target molecular species may be one or more. Therefore, the material analysis result includes at least one molecular species. The material analysis result characterizes what kind of molecule the sample to be tested may be.

[0065] In some embodiments, the substance analysis result may further include the content corresponding to each molecular species.

[0066] Figure 2 The flowchart of another Raman spectrum testing method according to an exemplary embodiment of the present disclosure is shown. The Raman spectrum testing method is applied to a cloud database.

[0067] like Figure 2 As shown, the Raman spectroscopy testing method may include the following steps:

[0068] S21. Receive spectral data uploaded by a mobile terminal.

[0069] The spectral data is obtained by dispersing the sample to be tested into an aqueous solution, dripping the aqueous solution onto the SERS chip, and then performing a Raman spectral test on the SERS chip with the sample to be tested dripped onto the SERS chip through a handheld Raman spectrometer, and is transmitted to the mobile terminal through the handheld Raman spectrometer.

[0070] S22, analyzing the spectral data to obtain material analysis results of the sample to be tested.

[0071] S23. Feedback the substance analysis result to the mobile terminal.

[0072] Optionally, the cloud database analyzes the spectral data to obtain the material analysis results of the sample to be tested, which can be: comparing the spectral data with the reference spectral data of each molecular type to obtain target reference spectral data whose similarity with the spectral data is greater than a threshold value; generating the material analysis results according to the target molecular type corresponding to the target reference spectral data.

[0073] The material analysis result includes at least one molecular species.

[0074] Optionally, the Raman spectroscopy testing method may further include: updating a cloud database according to the spectral data and the material analysis results.

[0075] By continuously updating the cloud database with spectral data uploaded by users, the cloud database can be continuously optimized and improved, so that the accuracy of material analysis results is continuously improved.
