Could there be a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome using fluorescence ...
Scientists have long been working on improving their ability to use lasers to move small objects without actually touching them. This method of 'optical trapping and manipulation' is already utilized in optics, biological ...
The Pazyryk carpet is the world's oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St. Petersburg, Russia. The carpet, which was made out of new wool at around 400 BC, is one of the most ...
The latest developments in fluorescence microscopy make it possible to image individual molecules in cells or molecular complexes with a spatial resolution of up to 20 nanometres. However, under certain circumstances, an ...
Organic molecules that capture photons and convert these into electricity have important applications for producing green energy. Light-harvesting complexes need two semiconductors, an electron donor and an acceptor. How ...
Optical investigations and manipulations often form the core of biological experiments. In a new report now published in Science Advances, Kazuki Okamato and a team of scientists in pharmaceutical sciences, neuroscience, ...
Nanomaterials researchers in Finland, the United States and China have created a color atlas for 466 unique varieties of single-walled carbon nanotubes.
Scientists led by the ESRF, the European Synchrotron, Grenoble, France and the University of Copenhagen, Denmark, have discovered the composition of red and black inks in ancient Egyptian papyri from circa 100-200 AD, leading ...
Researchers at Rice University and Baylor College of Medicine have developed a new method to isolate specific cells, and in the process found a more robust fluorescent protein.
Multicolor single-mode polarized microlasers containing an output range from visible light to the near-infrared have significant applications in photonic integration and multimodal chemical sensing or imaging applications. ...
