A novel electrochemical immunosensor built on three dimensional carbon nanotube-conducting polymer (CNT-CP) network is reported for detection of Hepatitis B surface antigen (HBsAg) in human serum. The CNT-CP network is prepared by drop-drying of CNT solution on glassy carbon electrode, followed by electrochemical polymerization of poly (pyrrole propionic(More)
has developed a new ionospheric sounding system for about seven years. The first system is used for ionospheric oblique backscattering detection and is called the Wuhan ionospheric oblique backscattering sounding system (WIOBSS). The WIOBSS is a portable monostatic backscatter ionosonde for ionospheric research and high-frequency (HF) channel management ,(More)
Long-term use of immunosuppressive agents could bring many side effects. Recently, 3-Hydroxy-3-methyl-gutaryl coenzyme A reductase inhibitors (statins) have been reported to be immunomodulatory besides lowering serum cholesterol level. The aim of this study was to investigate the effects of statins on composite tissue allografts and T lymphocyte in vivo and(More)
The increasing prevalence of digital technology brings great convenience to human life, while also shows us the problems and challenges. Relying on easy-to-use image editing tools, some malicious manipulations, such as image forgery, have already threatened the authenticity of information, especially the electronic evidence in the crimes. As a result,(More)
66 samples from the human oral mucosa tissue, including 43 normal and 23 malignant tissue samples were measured by confocal Raman microspectroscopy. The low signal-to-background ratio spectra from human oral mucosa tissues were obtained by this technique without any sample preparation. A preprocessed algorithm based on wavelet analysis was used to reduce(More)
