Scientists led by Nobel Laureate Stefan Hell at the Max Planck Institute for Medical Research in Heidelberg have developed a super-resolution microscope with a spatio-temporal precision of one nanometer per millisecond. An improved version…

"Phospholes can be modified by certain chemical reactions, which has a major impact on the colour and efficiency of the fluorescence of the molecule. Another special feature of these substances is their propeller-like structure,"…

UV light makes it possible to see intricate structures of fossils that are barely visible in normal daylight. This method has often been used on the fossilised seashells from the Earth's current geological era to reveal patterns of colour…

Researchers have developed a low-cost, simple imaging system that uses tumor-targeting fluorescent molecules to determine the depth of tumor cells in the body. The portable system could eventually help surgeons distinguish between healthy…

Standard medical imaging readily detects most solid brain cancers, one third of which are gliomas. Unfortunately, two complex surgeries are often necessary. But now, researchers from Japan may have devised a way to perform the initial…

An optical fiber as thin as a strand of hair holds promise for use in minimally invasive deep-tissue studies of patients' brains that show the effects Alzheimer's disease and other brain disorders. The research could set the stage for…

Concrete fractures that are invisible to the naked eye stand out in images produced through a technique created at Rice University. A collaboration between research groups at Rice and the Kuwait Institute for Scientific Research discovered…

Cell membrane coated biomimetic nanoparticles (NPs) have been widely studied in nanomedicine because of their unique properties such as immune escaping, long blood circulation, specific molecular recognition and efficient cancer targeting,…
