| 2 | Confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature显示文摘Laser speckle imaging has been widely used for in-vivo visualization of blood perfusion in biological tissues.However,existing laser speckle imaging techniques suffer from limited quantification accuracy and spatial resolution.Here we re-port a novel design and implementation of a powerful laser speckle imaging platform to solve the two critical limitations.The core technique of our platform is a combination of line scan confocal microscopy with laser speckle autocorrelation imaging,which is termed Line Scan Laser Speckle Autocorrelation Imaging(LS-LSAI).The technical advantages of LS-LSAI include high spatial resolution(~4.4μm)for visualizing and quantifying blood flow in microvessels,as well as video-rate imaging speed for tracing dynamic flow. | E Du Shuhao Shen Anqi Qiu Nanguang Chen | 2022 | Opto-Electronic Advances2022，5，2： | 0 |
| 3 | Advanced optical microscopy methods for in vivo imaging of sub-cellular structures in thick biological tissuesl显示文摘Optical microscopy has become an indispensable tool for visualizing sub-cellular structures andbiological processes.However,scattering in biological tissues is a major obstacle that preventshigh-resolution images from being obtained from deep regions of tissue.We review commontechniques,such as multiphoton microscopy(MPM)and optical coherence microscopy(OCM),for diffraction limited imaging beyond an imaging depth of 0.5 mm.Novel implementations havebeen emerging in recent years giving higher imaging speed,deeper penetration,and better imagequality.Focal modulation microscopy(FMM)is a novel method that combines confocal spatialfltering with focal modulation to reject out-of-focus background.FMM has demonstrated animaging depth comparable to those of MPM and OCM,near-real-time image acquisition,and thecapability for multiple contrast mechanisms. | Nanguang Chen Shakil Rehman Colin J.R.Sheppard | 2014 | Journal of Innovative Optical Health Sciences2014，7，5： | 0 |
| 4 | Aqueous Solution Preparation of Ruthenium Nanoparticles Using Ammonium Formate as the Reducing Agent显示文摘Ruthenium, one of the platinum group metals, has drawn much attention due to its catalytic behavior, hardness, electrical conductivity and density. Ruthenium particles are usually prepared on a small scale by the polyol process, however, the size of the obtained ruthenium nanoparticles is most below 10 nm. In this work, ruthenium particles about 200 nm in diameter were obtained in aqueous solution by using ammonium formate as the reducing agent. To have a better control of particle's size and shape, the effects of PVP, mixing mode, reaction temperature, solution pH and calcination temperature were investigated. | LIU Shaohong CHEN Jialin GUAN Weiming BI Jun CHEN Nanguang CHEN Dengquan LIU Manmen SUN Xudong | 2012 | 贵金属2012，33，A01： | 0 |
