Scientists are thrilled to use a microscope which can finally offer first colored images. It was tough for biologists to use a lens which could only provide gray images because it is hard to identify a virus. It is a very hard task to deal with because when we think about microscopic livings we need to think of a darkened environment too.
- The development of first colored images provided by a microscope was a total success.
- Using this technology, biologists are able to analyze specific parts of the molecules.
Photons which are responsible for discerning color become ungainly to deal with microscopic entities. If scientists need to observe molecules, bacteria or viruses crossing cell walls, they will need to use an electron microscope. In the 1930s was designed the electron microscope. The device is developed to attack a chemically-prepped specimen with electrons by using electromagnetic loops.
The image which is produced is more similar to a shadow casting than an actual picture. The particles unveil texture, contours, depth, and shapes, but no colors. Using colors is significant to notice some aspects which are hidden in gray images.
Scientists at the Center for Research in Biological Systems at UC San Diego have designed a technique for accentuating color in an electron microscopic picture. This revolutionary breakthrough was recently published in Cell Chemical Biology magazine. It implies two different technological evolutions.
Firstly, they handle microscopic entities using earth metals. Secondly, experts will analyze them employing a particular type of electron microscope which is commonly invoked to examine new synthetic structures. The process of colorizing develops like a usual electron microscopy. The microscopic units get fed with metal materials and then a grayscale capture is created.
Next, the molecule receives several kinds of rare metals which are known as lanthanides. These can adhere to certain kinds of particles, making them visible to the electron microscope. The experts are in charge of processing the capture, being responsible for assigning a color to each layer, placing the image on top of the grayscale base picture.
Mark Ellisman, who is the co-author of the research, but also a microscopist at CRBS, has argued that the use of colorizing unveils the essential components of the microscopic units which need to be analyzed. All the other things remain in gray. According to the interaction between the molecules or viruses, biologists have designed a method of assigning a different color to every type of relations. Currently, the team managed to implement only 2-3 colors to the microscope. They will work on further development.
