    Particulate matter (PM), made up of a variety of organic and inorganic substances, is found to be harmful to human health. Due to its small size, this combination of substances can enter the body by the respiratory route and cause all kinds of related diseases, such as lung cancer, trachea, esophagus. In addition to this, the 1 micron particles can enter the circulatory system and cause associated problems such as stroke and cardiovascular damage. As a result of this, especially in the mainly affected cities, such as Medellín, they will come looking for methods to deal with this problem, suggesting the use of cutting-edge technology to try to largely solve PM contamination, however, the contributions that are They have made an impact on closed spaces, without identifying that they can be very expensive to maintain, on the other hand, a level outside the city or in outdoor conditions. The use of technology has been very low, and containment measures translate into social and mobility strategies such as spike and plate extension. In this study, the use of technology in outdoor conditions is proposed, through the use of photobioreactors and microalgae to evaluate the capture potential that these microorganisms have in the capture of this PM and how it is possible to extrapolate it as a future solution to use it in The city of Medellín. As a conclusion of the experiment, it was found that the Scenedesmus Obliquus ATCC 457 microalgae (S. Obliquss ATCC 457) could grow up to 1.52 g / L and retain up to 61.07% of PM 1, 65.45% of PM 2.5 and 87.01% of PM 10.
