The proposed technology employed gold nanoparticles (AuNPs) to enhance the sensitivity to achieve PCT rapid detection. The fabricated sensors comprise of suspended glass planar waveguides on glass substratesare integrated with microfluidic channels without vacuum-less processes. The results show good performance with a LOD of 0.871 fg/ml for PCT detection modified. The fabricated sensors show very promising results with a high throughput, enabling mass production for rapidsensitive bio-detectionalso fulfils POCT requirements.

We have developed a low-costportable reader for thermometric lateral flow immunoassay (TLFIA) using colloidal goldlatex beads as reportersa continuous-wave green laser as the heating source. Instead of using infrared cameras, a single-element infrared sensor is employed for temperature sensing without compromising the sensitivity of the reader. The thermometric assay provides a 10× higher sensitivity than color visualizationthe results are sufficiently quantitative to support decision making in point-of-care testing for infectious diseases (such as COVID-19).

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.

We provide antibody-based solutions to human diseases with short development course at low cost, are based on the phage-displayed GH (Generic Human) synthetic antibody libraries designedconstructed with enabling approaches, leading to the throughput capacities to uplift the innovativenessproductivity in developing antibody therapeuticsdiagnostics. In conjunction with the core technologies, antibody bioinformatics capable of extracting knowledge from big data of human antibody repertoires is used to elucidate human antibody responsesto assist antibody library design.
