Both cardiac cells in the heart and neurons in the brain communicate by electrical signals, and these messages of communication travel fast from cell to cell as 'excitation waves'. Interestingly, such...
Light-activated genes might be precisely controlled and targeted（图）
Light-activated genes precisely controlled targeted
2015/3/4
Duke University researchers have devised a method to activate genes in any specific location or pattern in a lab dish with the flip of a light switch by crossing a bacterium’s viral defense system wit...
Classification of Protein Localization Patterns Obtained via Fluorescence Light Microscopy
Protein Localization Microscopy
2009/12/22
We describe a method of classifying cellular
protein localization patterns based on their appearance in
uorescence light microscope images. Images depicting cellular
protein localization were obtai...
Photocatalytic bactericidal action of fluorescent light in a titanium dioxide particle mixture: an in vitro study
titanium dioxide particle mixture vitro
2009/12/16
Traditional titanium dioxide (TiO2) has photocatalytic bactericidal properties only under ultraviolet (UV) irradiation, which restricts its use in clinical treatment regimens. In this study, we evalua...
Synthesis and Bioconjugation of Gold Nanoparticles as Potential Molecular Probes for Light-Based Imaging Techniques
Synthesis Bioconjugation Potential Molecular Probes
