We report the first observation of infrared (IR) and mass spectra of neutral, aliphatic amino acid clusters: the example presented herein is for (valine)n, n = 2-5. The clusters are generated in a supersonic expansion and their IR spectra are recorded in various fragment and (valine)n-1H+ (n = 1-2) mass channels. The ions are created by single photon ionization with a VUV laser at 118 nm (10.5 eV/photon)...
Real-time 1O2 detection in photodynamic therapy(PDT) is meaningful but difficult. Chemiluminescence(CL) method has a high signal/noise ratio on in vivo 1O2 detection. Results indicate there was a remarkable relationship between tumor cure rate and CL.
By combining SERS experiments with DFT calculations, the orientation of methylene blue (MB+) absorbed on the silver colloid at different concentrations are discussed. The results indicate MB+ adopts a parallel fashion at low concentration while a perpendicular one at high concentration.
Novel electrochemiluminescence (ECL) nanoprobe was constructed, and the high sensitivity afforded by the current ECL assay based on ECL nanoprobe without the PCR amplification of telomerase reaction products.
Detection of negative kidney calculus is difficult using X-ray imaging. This article shows that thermoacoustic imaging as a novel and complementary medical modality may become a fast and effective method for detecting negative kidney calculus.
Autophagy is a mechanism which protects cell itself from hypoxia, starvation and other adverse environments. It's meaningful for cell survival. We observed the autophagy of tumor cells stimulated by heat shock in real-time with confocal laser scanning microscope system. The results showed that: heat shock induced autophagosomes in ASTC-a-1 cell are produced after 2 hours of recovery in 37degC.
This paper designs a fabric image registration method after researching texture of fabric. It can find the commonality area of two images quickly and accurately. Generally speaking, it is a good choice to solve the image registration with the relativity of two images in random texture images. However, repeated on high-resolution images to do Fourier Transform will decrease real-time of detection system...
