Yakovlev shed light deeper human brain
2017/9/1
The inner workings of the human brain have always been a subject of great interest. Unfortunately, it is fairly difficult to view brain structures or intricate tissues due to the fact that the skull i...
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...
Visible Light Cured Thiol-vinyl Hydrogels with Tunable Gelation and Degradation
Hydrogels Visible light photopolymerization Tissue engineering
2015/1/12
Hydrogels prepared from photopolymerization have been widely used in many biomedical applications. Ultraviolet (200-400 nm) or visible (400-800 nm) light can interact with light-sensitive compounds ca...
Monte Carlo Simulation to Study Propagation of Light through Biological Tissues
Monte Carlo Simulation Light Propagation Absorption Coefficient Scattering Coefficient Tumor Hypoxia Photoacoustic Tomography
2015/1/12
Photoacoustic Imaging is a non-invasive optical imaging modality used to image biological tissues. In this method, a pulsating laser illuminates a region of tissues to be imaged, which then generates ...
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
2009/9/7
We have synthesized and characterized gold nanoparticles (spheres and rods) with optical extinction bands within the “optical imaging window.” The intense plasmon resonant driven absorption and scatte...
Light Reveals Breast Tumor Oxygen Status
Light Breast Tumor Oxygen Status biological specifics
2009/12/17
Light directed at a breast tumor through a needle can provide pathologists with biological specifics of the tumor and help oncologists choose treatment options that would be most effective for that in...
Portable light transmission measuring system for preserved corneas
Portable light transmission measuring system preserved corneas
2010/2/26
By comparing the three methods and using the expertise of eye bank trained personnel, a table for quantifying corneal transparency with the new device has been developed. The correlation factor betwee...
Safety assessment of near infrared light emitting diodes for diffuse optical measurements
Safety assessment diffuse optical measurements
2010/3/1
In this study, we demonstrate that the major risk source of the LED in direct contact with skin is the conducted heat of the LED semiconductor junction, which may cause serious skin burns. Adjusting o...
