Researchers in the U.S. and China have developed a method to transform a smartphone into a fluorescence microscope. The handheld smartphone-fluorescence microscope (HSFM) device allows complex biomedical analyses both rapidly ...
It is the holy grail of light microscopy: improving the resolving power of this method such that one can individually discern molecules that are very close to each other. Scientists around the Nobel laureate Stefan Hell at ...
