Microsopy

  Hi,

            This week in Microbiology classes we learned about the topic, Microscopy. This topic was easy to understand but it is kind of boring because most of us have learned about microscope in our early education. However, the topic that was taught throughout the week was even more detailed and more in depth than what was taught during our high school years and matriculation studies. 

             To make the lesson more enjoyable, Dr. Wan decided to make a group of students present the topic in an interesting way. Hence, they came up with a story that was successfully delivered in a fun way but to me it was kinda illogical.However, that made us all paid attention and showed interest in the learning process.

            From that, I have gained a lot of knowledge about the topic, Microscopy and now I can differentiate the type of microscope used to observe the specimens.There are many types of microscope such as optical, electron, scanning probe and scanning acoustic microscope.

            Bright field microscope is a type of optical microscope which view  specimen against brighter background.Its function is contradicting with the dark field microscope. Another type of optical microscope is the phase-contrast microscope, which usually used for motile specimen or to detect the bacteria components.The fluorescence  microscope is an optical microscope but the specimen is tagged or naturally fluorescing against dark background.The fluorescence stain are called fluorochromes.

           The transmission electron microscope is a type of an electron microscope which can be used for analysing internal structures while the scanning electron microscope can only view the surface structures. Other than that, I know that scanning probe microscope needs a probe while scanning acoustic microscope uses sound to study the specimen.

           Not only did we learned about Microscopy, we also did an online mid map on the topic Prokaryotes which are very hard to do unless we have a strong wifi connection. It would drive me crazy doing it for hours and suddenly all my points disappeared. However, it was  a good learning experience and now I know how to make a mind map online. Yippie!!!
