Magnification and High Resolution. One of the most significant advantages of electron microscopy is the ability to produce powerful magnification. It offers a higher resolution than what is possible with optical microscopy and plays an important role in many areas of scientific research for this reason.
Main type. Fentanyl is a powerful narcotic painkiller that is used to treat severe pain. It is an opioid, meaning that it is a fully synthetic (man-made) drug based on the opiate group of drugs derived from the Opium poppy such as Morphine and Heroin.Because of its potency (roughly 100 times stronger than morphine) it is generally only used in the management of severe pain and as a hospital analgesic.t is an opioid, meaning that it is a fully synthetic (man-made) drug based on the opiate group of drugs derived from the Opium poppy such as Morphine and Heroin.

There are dozens of synthetic and natural versions of these opiate-based (narcotic) pain relievers, all carrying various levels of strength. Whereas fentanyl is considered the strongest, morphine seems to be the basis by which all drugs of this class are compared.
