Scientists at the Center for Research and Advanced Studies (Cinvestav) in Mexico developed a chip (also known as cDNA microarray) that allows detection of the RNA strand of the dengue fever virus.
The genetic information contained in this scientific tool pinpoints the exact serotype of malaria that an infected person or mosquito is carrying.
According to Maria de Lourdes Muñoz Moreno, researcher at the Department of Genetics and Molecular Biology at Cinvestav, the problem is that sometimes dengue fever cases are diagnosed improperly. “A simple flu could be mistaken for dengue fever; or on the contrary, the latter could be diagnosed as a cold,” said the specialist.
The chip allows analysis of the complementary strand of DNA (cDNA) obtained from the dengue fever virus being carried by the infected patient. Cinvestav specialist explains that said cDNA is covalently linked to a slide (substrate) that can be a glass or paper.
