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.

"Visible Light Communication (VLC)" is the best candidate for the next generation of network communication owing to its wide bandwidthscompatibility with solid-state lighting devices. Our proposed technology features a novel multilevel photosensing memory which can integrate the photosensing, memorycomputation components for VLC into one device. This device is based on a thin film transistor, where the oxide semiconductor is added with gold nanoparticles to form a "co-active layer" in order to expand the visible light sensing spectrumefficiently convert the light signal into a current signal. It not only simplifies the production processreduces the cost, but also accelerates the signal transmission speed, which further advances the future mobile comm

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).
