Malaria, a serious infectious disease and considered neglected, is a relevant public health problem, responsible for approximately 1 million of deaths per year. It is caused by protozoan parasites of the genus Plasmodium, being Plasmodium falciparum the most severe and potentially fatal specie, which requires an early detection of the disease in order that the appropriate treatment enables the reduction of mortality rates due to its contamination.Lateral flow immunoassay (LFIA) is a widely used paper-based diagnostic system and consists of a fast, practical and low cost test that not requires specific knowledge and equipment for its use. It is quite applied for screening and can generate qualitatively and quantitatively information about the presence of an analyte by using antibodies or antigens conjugated with any type of marker, which will be responsible for identifying the interaction between antigen and antibody by different types of detection.This work aims the construction of a paper-based analytical device for the diagnosis of malaria caused by Plasmodium falciparum by the conjugation of different markers to the antibody in order to provide an increase in the sensitivity by amplifying the signal, allowing the colorimetric, fluorescence and electrochemical detection of the HRP2 protein at the early stage of the disease. The most promising detection method for the development of a technological product, by comparative analysis of the spot tests, will be employed in a lateral flow immunoassay system. (AU)
