Nanosensors for Diagnosis of Infectious Diseases.

Infectious diseases have become a severe global public health problem. Timely and accurate diagnosis of infected individuals is the key step to control the spread of infectious diseases. Nanosensors that combine the advantages of nanomaterials and biosensing technology have been utilized for sensitive, selective, and rapid disease diagnosis and gained great attention within the chemistry, biology, and medical communities. This review presents a broad overview of a wide range of nanosensors for diagnosis of infectious diseases using different methodologies. We also outline point-of-care nanosensing methods and discuss their use in pathogen detection. This review concludes with challenges and opportunities for diagnosis of infectious diseases using nanosensors.
