The present invention relates generally to a ribonucleic acid test panel and a ribonucleic acid test device, and more particularly to a ribonucleic acid test panel and a ribonucleic acid test device, which can shorten the test time and lower the cost.
Currently, when it is desired to test the disease of a user, (such as Kawasaki disease, colorectal cancer, hand-foot-and-mouth disease, novel coronavirus (COVID-19) or other RNA carrying virus), it is necessary to send the user to a hospital and use a measure platform to make the mark, (such as a polymerase chain reaction (PCR) analyzer). Thereafter, it is necessary to take the user's blood and use an RNA extraction equipment to extract the miRNA virus. Then, the steps of adding miRNA, adding miRNA marking agent and dropping the miRNA marking agent onto the miRNA chip to dye and scan are sequentially performed. According to the brightness change of the luminescence and by means of comparing the data, it can be known whether the user is confirmatively infected. Therefore, conventionally, when testing the RNA (or miRNA) virus, a professional apparatus (such as measure platform or RNA extraction equipment) is needed. As a result, only a specific professional medical worker can operate these professional equipments so that the test difficulty and cost are high. In addition, conventionally, the virus is tested by means of luminescent marking. Such conventional test procedure is troublesome and complicated. Therefore, it takes at least two hours or even more than two days to have the test result. As a result, the test time is quite long.
It is therefore a primary object of the present invention to provide a ribonucleic acid test panel, which can shorten the test time and lower the cost.
It is a further object of the present invention to provide a ribonucleic acid test panel, which can be easily operated and conveniently used.
It is still a further object of the present invention to provide a ribonucleic acid test device, which can shorten the test time and lower the cost.
It is still a further object of the present invention to provide a ribonucleic acid test panel, which can be easily operated and conveniently used.

The present invention provides a ribonucleic acid test panel and a ribonucleic acid test device. Please refer to
The multiple sensation electrode layers include a transparent or nontransparent first sensation electrode layer 113 and a transparent or nontransparent second sensation electrode layer 114. The first sensation electrode layer 113 has multiple first sensation electrodes 1131 (such as X-axis sensation electrodes) disposed in the sensation section 1111 of the first surface 111. The second sensation electrode layer 114 has multiple second sensation electrodes 1141 (such as Y-axis sensation electrodes) disposed on the first sensation electrode layer 113. In this embodiment, the multiple first and second sensation electrodes 1131, 1141 are respectively X-axis sensation electrodes and Y-axis sensation electrodes, which are arranged to intersect each other. The multiple sensation electrode layers and the multiple electrode wiring layers 116 are, but not limited to, made of a metal material selected from a group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), antimony tin oxide (ATO) and any combination thereof. In practice, the metal material alternatively can be aluminum (Al), gold (Au), copper, silver (Ag), nickel (Ni), chromium (Cr) or any alloy thereof. In this embodiment, the multiple first and second sensation electrodes 1131, 1141 are, but not limited to, in a rhombus form. In a modified embodiment, the multiple first and second sensation electrodes 1131, 1141 alternatively can be in the form of a band, a strip, a wide band or a rectangle. In another modified embodiment, the multiple first sensation electrodes 1131 are arranged in the sensation section 1111 of the first surface 111 in a matrix or an array (such as M×N array) and the multiple second sensation electrodes 1141 are arranged on the first sensation electrode layer 113 in a matrix or an array (such as M×N array). In addition, the multiple first and second sensation electrodes 1131, 1141 are insulated from each other.
In another modified embodiment, the multiple first and second sensation electrodes 1131, 1141 of the first and second sensation electrode layers 113, 114 are correspondingly arranged on the first surface 111 of the substrate 11 in parallel to each other. The primer layer 115 is disposed on the first and second sensation electrode layers 113, 114 and insulated therefrom.
A first insulation layer 117 is disposed between the first and second sensation electrode layers 113, 114. The first insulation layer 117 is made of a material such as silicon dioxide (SiO2). The at least one primer layer 115 is formed and disposed on the multiple sensation electrode layers by means of such as printing or coating. The primer layer 115 is insulated from the multiple sensation electrode layers. In this embodiment, there are multiple primer layers 115 arranged on the second sensation electrode layer 114 at intervals. The primer layers 115 are made of polymer material for reacting with a corresponding specimen (such as the saliva of a user) carrying ribonucleic acid (or micro-ribonucleic acid). For example, in the case that the user's saliva, (that is, the RNA specimen) carries no RNA virus and cannot react and bond with the corresponding specific primer layer 115, there is no electrical change (such as no capacitance change or dielectric coefficient change). This is like the user's finger fails to touch such as the touch sensation section 1111 so that a constant coupling capacitance will exist between the multiple first and second sensation electrodes 1131, 1141 of the first and second sensation electrode layers 113, 114. At this time, the electrical field (electric field line) between the multiple first and second sensation electrodes 1131, 1141 is constant. In the case that the user's saliva, (that is, the RNA specimen) contains therein RNA virus and reacts and bonds with the corresponding specific primer layer 115, there is apparently electrical change (such as capacitance change or dielectric coefficient change). This is like the user's finger touches the touch sensation section 1111 so that a capacitance is formed between the primer layer 115 and the second sensation electrode layer 114. At this time, the electric field line is partially connected to the correspondingly primer layer 115 so that the electrical field (electric field line) originally constantly distributed between the multiple first and second sensation electrodes 1131, 1141 of the first and second sensation electrode layers 113, 114 will change, (that is, the electric field changes). Accordingly, the capacitance value of the coupling capacitance between the multiple first and second sensation electrodes 1131, 1141 will be changed, (that is, the capacitance value will change).
Moreover, the aforesaid primer layer 115 is a primer, which will only react with a corresponding specific virus (such as Kawasaki disease, colorectal cancer, hand-foot-and-mouth disease, novel coronavirus (COVID-19) or other RNA virus). For example, a specific primer is previously designed to detect such as novel coronavirus (COVID-19). In the case that the user's saliva, (that is, the specimen) contains therein novel coronavirus (COVID-19), the RNA novel coronavirus (COVID-19) will react and bond with the corresponding primer layer 115 for specifically detecting the novel coronavirus (COVID-19) and there is apparently electrical change. This means that the user is confirmed (positive) to have the novel coronavirus (COVID-19), (that is, infected with the virus). In the case that the user's saliva, (that is, the specimen) carries no virus or carries some other virus (such as Kawasaki disease), the virus will not react and bond with the corresponding primer layer 115 for specifically detecting the novel coronavirus (COVID-19) and there is no electrical change. This means that the user is not confirmed (negative) to have the novel coronavirus (COVID-19), (that is, not infected with the virus). The aforesaid primer is a small segment of single-chain DNA or RNA as a starting point for DNA reproduction. The primer exists in the natural creature for DNA reproduction (RNA primer) or is an artificial primer (generally DNA primer) produced in polymerase chain reaction (PCR) and composed of nucleotide.
A second insulation layer 118 is disposed between the multiple primer layers 115 and the second sensation electrode layer 114. A third insulation layer 119 is disposed between the first sensation electrode layer 113 and the substrate 11. The second and third insulation layers 118, 119 are made of a material such as silicon dioxide (SiO2). In a modified embodiment, the third insulation layer 119 can be omitted so that the first sensation electrode layer 113 is disposed on the first surface 111 of the substrate 11 (such as glass substrate or PET substrate).
The multiple primer layers 115 are such as in the form of elongated strip and positioned in the sensation section 1111 in X-axis direction (or Y-axis direction). The multiple primer layers 115 are arranged on the second insulation layer 118 at intervals through the intersections of the first and second sensation electrodes 1131, 1141. In a preferred embodiment as shown in

In this embodiment, the control unit 21 can be arranged in three aspects as follows:
In the first aspect, as shown in
In this embodiment, the display member 23 is, but not limited to, a display for displaying the test result information. In a modified embodiment, the display member 23 is alternatively multiple light-emitting diodes (LED). That is, the test result is shown by means of multiple lights. For example, the red LED light is turned on to indicate positive and case confirmed, while the blue LED light is turned on to indicate negative and case unconfirmed. In this embodiment, the power supply unit 26 is a battery for supplying power to the display member 23, the processing unit 24, the wireless transceiver unit 25 and the ribonucleic acid test panel 1. In a preferred embodiment, the power supply unit 26 can be a rechargeable battery and a connection port (such as micro USB connection port) is disposed on the circuit board 22 for charging the power supply unit 26.
In this embodiment, the wireless transceiver unit 25 is a Bluetooth unit (such as Bluetooth transceiver). The Bluetooth unit is wirelessly connected to an electronic device (such as an intelligent mobile phone, an intelligent watch, a computer, a notebook or a tablet, which is not shown). Via the Bluetooth unit, the processing unit 24 wirelessly transmits the test result information to the electronic device to be shown. In practice, the wireless transceiver unit 25 is a Wi-Fi unit or a radiofrequency (RF) unit.
The second aspect is as shown in
When a user desires to test the Kawasaki disease virus (or so-called mucocutaneous lymph node syndrome virus), the user can drop his/her saliva, (that is, the specimen) onto the sensation section 1111. In the case that the saliva contains the miRNA of the Kawasaki disease virus selected from miR-30e-3P, the miRNA of the Kawasaki disease virus will react and bond with the corresponding primer layer 115 for detecting the Kawasaki disease virus. Thereafter, there is apparently electrical change (such as capacitance change). According to the capacitance change signal transmitted from the multiple first and second sensation electrodes 1131, 1141, the control unit 21 judges that there is electrical change of the specimen and the primer layer 115 and generates the test result, which is transmitted to the processing unit 24. According to the test result that there is electrical change, the processing unit 24 processes the signal to transmit the test result information to the display member 23, whereby a user himself/herself can know the test result from the test result information displayed by the display member 23 (as shown in
Therefore, by means of the design of the ribonucleic acid test device 2 of the present invention, which tests the disease by means of electrical measure, the test time is effectively shortened such that the disease (such as disease virus) can be tested in fifteen minutes and the cost is lowered. Moreover, any user himself/herself can readily perform the test at home so that the test operation is simplified and the test can be quite conveniently performed.
The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in such as the form or layout pattern or practicing step of the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
