Viral Nano-Bio-Sensing and SARS-CoV-2: A Literature Review

As new advancements and technologies are emerging in this world, so is the spread of new diseases. The world, as we know it, is moving very fast. With this pace, diseases are also borne. The spread of new viruses, such as coronavirus disease-2019, require new technologies faster and more precise than ever before. Countries all around the world are connected, and moving from place to place has become easy. For that reason, pandemics are an increasing threat. A disease is considered a pandemic when it has spread through a large area, possibly worldwide and has become an international threat. In order to limit the spread of diseases, or viruses in particular, the early detection and diagnosis of patients is essential to decrease the number of infections. Biosensors play an important role in the medical field, such as in viral detection. Nanotechnology has gained a lot of interest in its use in bio-sensing. Nano-biosensors have shown more advanced properties than regular biosensors and thus are able to detect diseases faster and more precisely than before. Our main focus in this literature review is to explore new technologies and advancements made with nanotechnology and bio-sensing in viral detection, especially in the detection of severe acute respiratory syndrome-coronavirus-2.
