The recent COVID-19 pandemic has revealed the need to develop tests that are accurate, rapid, and inexpensive for the diagnosis of infectious diseases. This problem is relevant not only for viruses, but also for bacteria and parasites: the identification of pathogens at low concentrations by simple and accurate methods is still largely unsatisfied because these microorganisms are structurally complex and are incorporated in composite and diverse biological samples, which can create relevant interferences in pathogens' detection. Direct diagnostic approaches, such as microscopic examination, culture and molecular testing are carried out in equipped laboratories and require long waiting times to obtain the results. Recently developed point-of-care (POC) tests are a group of technologies that miniaturize tests into portable devices such that they can be performed both in well-equipped laboratories and outside the conventional laboratory setting. The present study aims to explore the feasibility and adaptability of newly developed platforms to detect: 1. a virus (SARS-CoV2), 2. a bacterium (Pseudomonas aeruginosa) and 3. a protozoan parasite (Leishmania infantum) in clinical specimens, such as blood and respiratory samples. These newly developed platforms are expected to overcome the current limitations of molecular testing (high cost, time required and need for well-equipped laboratories) and rapid testing (high number of false-negative results). In addition, the newly developed platforms may have important clinical application in low-income countries, which will benefit from a simple and inexpensive approach to detect the many infectious diseases that affect millions of people each year.
