In urease test we use indicater phynol red but bacteria positive appear as a pink color. why?

urease test media contains 2% urea and phenol red as an indicator.An increase inPH due to the production of ammonia results in a color change from yellow (ph6.8) to bright pink (ph8.2).

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

there is no
