 Biosensors are playing an increasingly important role in the diagnosis of infectious diseases. They have been used to detect various pathogens including viruses, bacteria, fungi, and parasites. These devices offer several advantages over traditional laboratory tests, such as speed, accuracy, and cost effectiveness. However, there are some drawbacks associated with these devices, such as specificity issues, low target numbers, and biological matrices. Additionally, economic factors may prevent widespread use of biosensors in resource-limited settings. Despite these challenges, advances in technology are making it possible to develop more efficient and reliable biosensor systems for the diagnosis of infectious diseases.
