The technology combines specific visual recognitionelectrochemical quantitative detection in a single portable device, providing instantconvenient copper ion detection. The sensing sensitivity has reached the standards of Taiwanthe United States for heavy metal detection for food, human body,environments. In use, this portableuser-friendly interface device not only makes it simple to report back to the EPA database for water quality analysis, but also it can be utilized for real-time detection from youngsters to the elderly.

Inorganic porous nanofibers with surfaceinterface defects are prepared through humidity-controlled electrospinninghigh-temperature annealing technology. Under the irradiation of light sources of different wavelengths (380~780 nm), the bound electrons stored in the valence band can be excited to the conduction band to form free electrons on the surface of the material, generating different intensities of microcurrents, light sensitivitymicrocurrent changes. Because the "inorganic nanofiber" technology has high uniquenesshigh product compatibility, it can be applied to a wide range of markets.

SeraParma™ COVID-19 IgM rapid test has high detection sensitivity, which can provide rapid detection of early COVID-19 infection. This SeraParma™ COVID-19 IgM rapid test can detect whether there are IgM antibodies produced in the early stage of infection (within 7 days of symptoms onset) with one drop of the specimen (serumfingertip blood) in 15 minutes by naked eyes compared with LFIA antibody rapid test. It is worth noting that the SeraParma™ COVID-19 IgM rapid test can accurately detect the patients with positive infection within 7 days of the onset of symptoms compared with LFIA.
