Explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your microscope stage.

microscope maintenance

the painted surfaces and the plastified parts of the microscope do not require any particular maintenance, they will be, if necessary, simply wiped with a cloth impregnated with detergent (avoiding to touch the optical parts).

on the other hand, it is essential that the optical parts of the microscope remain extremely clean.

the eyepiece tubes will never be left without cover to prevent impurities from entering the optical tube.

it is necessary to make the habit to protect the device by a cover, in order to avoid that the dust and small dirt are deposited on the optical surfaces, which would entail a decrease of the performances and the quality of the final image .

preservation of sample slides

the cytological samples are received either freshly or most often fixed (pancreas, the material being deposited in a fixer bottle and / or spread on slides by the clinician. the most widely used preservation medium are cytorich-red coloration, or shandon coloration, which are available on request from the laboratory.

look at the specimen from the side, not through the eyepiece when you are turning the low power objective as close as possible to the specimen to begin your observations. never use the coarse adjustment knob while using the high power objective. never turn the fine adjustment knob more than a fourth turn to adjust the focus while using the high power objective.

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.
