ABSTRACT
The mass testing tactic is among the main strategies to fight a virus pandemic. It allows for an early diagnosis in the initial phase of the disease and reduces disease transmission. In this sense, there is a growing interest in developing devices with high sensitivity, selectivity, and fast detections. With this purpose, nanobiosensors are presented as a promising alternative, produced from nanomaterials with different structures and properties. On biosensing, NMs comprise transduction elements (transducers) associated with biomarkers to recognize and amplify different signals when interacting with biological material. The primary transducers involve optical and electrochemical methods. Gold nanoparticles (AuNPs) and carbon-based, such as graphene, graphene oxide, and carbon nanotube (CNT), make up most NMs used in biosensing. For such application, the use of magnetic nanoparticles (MNPs) and quantum dots (QDs) of different compositions, such as the basis of cadmium and tellurium (CdTe QDs), are also widely studied. In addition to applications in biosensing, nanomaterials can be applied in biomarker immobilization and extraction procedure in standard tests such as RT-PCR and LFIA (ELISA). NMs allow for the improvement of different techniques used in viral detection, presenting diverse and unique solutions for health crisis moments, including for Covid-19. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
