| Sumario: |
Biosensors are measurement devices that can sense several biomolecules, and are widely
used for the detection of relevant clinical pathogens such as bacteria and viruses, showing outstanding
results. Because of the latent existing risk of facing another pandemic like the one we are living
through due to COVID-19, researchers are constantly looking forward to developing new technologies
for diagnosis and treatment of infections caused by different bacteria and viruses. Regarding that,
nanotechnology has improved biosensors’ design and performance through the development of
materials and nanoparticles that enhance their affinity, selectivity, and efficacy in detecting these
pathogens, such as employing nanoparticles, graphene quantum dots, and electrospun nanofibers.
Therefore, this work aims to present a comprehensive review that exposes how biosensors work in
terms of bacterial and viral detection, and the nanotechnological features that are contributing to
achieving a faster yet still efficient COVID-19 diagnosis at the point-of-care.
