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).

This rapid diagnostic device for monitoring the abnormal growth of the endometrial tissue is expected to allow women to detect whether VEGFIL-6 are too high at home in a simplerapid manner. These two factors are also increasing in some gynecological cancers. Through the new device, it is convenient for women to self-monitoring women physiologically-relevant diseasespossible causes of abnormal bleeding in the future,seek appropriate medical treatment early.
