Technical Field

[0002] Microorganisms mainly include bacteria, fungi and viruses, which exist in almost all animals and plants and play an important role in our lives. Some of them are beneficial and are widely used in the food and pharmaceutical industries, such as yeast, penicillium, lactobacillus, etc. However, every year a large number of pathogenic microorganisms still damage human health and cause significant economic losses. The allergic flexible paper-based chip sensor can use enzymes to detect specific biomarkers in body fluids. It is usually achieved by using its material properties and sensing technology. The biomarkers in the detected body fluids are combined with the recognition molecules on the surface of the sensor. The electrical changes caused by the binding reaction are recorded, and the signal is analyzed by the data analysis system to determine the concentration or presence of the biomarker. The advantages of the allergic flexible paper-based chip sensing device are low cost, environmental friendliness and flexible application, and are suitable for various real-time monitoring and health management scenarios.

[0003] In actual use, existing allergic flexible paper-based chip sensing devices are not convenient for effectively detecting the effects of biomarkers in body fluids, and the detection notch is exposed too early, which can easily affect the detection results.

This provides a convenient and effective new method for non-professionals to detect aluminum ion concentrations in water, both on-site and in real time. Furthermore, the device boasts portability, miniaturization, simple structure, rapid detection speed, ease of fabrication, and low cost.

[0005] Although the above patent provides a convenient and effective new way for non-professionals to detect the concentration of aluminum ions in water bodies in real time on site, and the paper-based chip sensor device has the advantages of portability, miniaturization, simple structure, fast detection speed, simple production, and low cost, it is not easy to fix at any time and has strong sealing protection.
