Click the blue text to follow us Research Background The emerging photoelectrochemical (PEC) photodetectors possess unique characteristics for operation in liquid environments. Unlike electrochemical methods that require an external power source to generate electrical detection signals, PEC photodetectors separate the electrical detection signal from the light excitation source, resulting in negligible background signals and reduced … Read more
In the field of life sciences, the sugar chains on the surface of cells act as complex “molecular codes” that carry critical biological information. Among them, sialic acid, a sugar molecule with a nine-carbon backbone, is typically located at the terminal of cell surface sugar chains and plays an important role in various biological processes … Read more

Recently, Carnegie Mellon University reported a new ceramic 3D printing technology based on aerosol jet printing (3D-AJP), which can be used to manufacture high-performance ceramic materials with complex microstructures. This technology achieves binder-free, support-free nano-printing to create complex ceramic structures at micro-scale (minimum feature size of 20 micrometers) with extremely low shrinkage rates (2-6%) after … Read more
Respiratory viral infections pose a significant challenge to global public health, and rapid and accurate detection is crucial for timely diagnosis and treatment. Traditional detection methods such as ELISA and PCR have limitations including complex operations and long processing times. Lateral flow immunoassay (LFA) test strips have become an ideal instant detection technology due to … Read more
Hue-Recognizable Lateral Flow Immunoassay Based on High Color Purity Semiconductor Nanoplatelets Introduction The lateral flow immunoassay (LFIA) has been widely used for the rapid screening of infectious diseases during the COVID-19 pandemic. However, due to the physiological limitations of the human eye in distinguishing monochromatic brightness variations, commercial colloidal gold and traditional fluorescent LFIA can … Read more
