第七届全国青年计算物理学术会议

作者： y.X.Wang Applied Ion Beam Physics Laboratory Institute of Modern Physics Fudan University

Using the first principle method,we investigated the effect of tungsten carbide (WC) surface layers on hydrogen retention in *** results showed that C is not capable of efficiently capturing H atoms because of Coulombic repulsion between negatively charged C and H atoms in tungsten. Meanwhile,the repulsive force enhances the migration barrier for H to travel through WC layers

Photonics Asia 2004;Sensors and Imaging

作者： Osuk y.Kwon

These proceedings contain the papers presented at the Photonics Asia 2004 Advanced Sensors Systems and Applications conference, held 8-12 November 2004, in Beijing, China. This conference covered a number of key issues concerning recent progress in advanced sensors and their applications, in particular optical fiber sensors. After more than 20 years, worldwide research and development in the field of optical fiber sensors is still very active. This conference had many more papers submitted than that held two years ago. This strong growth may be due to significant reductions in the cost of most fiber optic components and the maturity of optical fiber sensors, such as fiber grating sensors and interferometric sensors.

Double-antibody-based nano-biosensing systemfor the onsite monitoring of SARS-CoV-2 variants

Microsystems & Nanoengineering 2023年第4期9卷 247-262页

The fast and reliable diagnosis of COVID-19 is the foremost priority for promoting public health ***, double-antibody-based immunobiosensor chips were designed, constructed, and exploited for clinicaldiagnosis. Gold nanoparticles/tungsten oxide/carbon nanotubes (AuNPs/WO3/CNTs) were used as the active workingsensor surface to support the chemical immobilization of a mixture of SARS-CoV-2 antibodies (anti-RBD-S and anti-RBD-S-anti-Llama monoclonal antibodies). The morphology and chemical functionalization of the fabricateddisposable immunochips was characterized using scanning electron microscopy (SEM), Fourier transform infrared(FTIR) spectroscopy, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). After full assayoptimization, the immunobiosensor showed a high sensitivity to detect SARS-CoV-2-S protein with limits of detectionand quantification of 1.8 and 5.6 pg/mL, respectively. On the other hand, for the SARS-CoV-2 whole virus particleanalysis, the detection and quantification limits were determined to be 5.7 and 17 pg/mL, respectively. The biosensorshowed a highly selective response toward SARS-CoV-2, even in the presence of influenza, nontargeting humancoronaviruses, and Middle East respiratory syndrome coronavirus (MERS-CoV). The immunochips exhibited distinctresponses toward the variants of concern: B.1>C.36.3>Omicron> Delta> Alpha coronavirus variants. For biosensorvalidation, twenty-nine clinical specimens were analyzed, and the impedimetric responses were positively detected fortwo Delta samples, eighteen Omicron samples, and six B.1-type samples in addition to three negative ***, the immunobiosensor was fabricated in the form of ready-to-use chips capable of sensitive detection ofvirus variants, especially variants of concern (VOC) and interest, in a specimen within 15 min. The chips providedinstantaneous detection with the direct application of clinical samples and are considered a point-of-care
