Sensor for detecting Viruses

The Need

The swift and accurate diagnosis of COVID-19 and other viruses is crucial in preventing their spread. Current detection methods like PCR and antibody testing have limitations, including long run times, sample preparation, and high false negative rates. Moreover, with the rapid mutation and proliferation of viruses, there is a need for adaptable diagnostic assays to detect new variants. A solution that offers quick, selective, and error-free virus detection is vital, especially for viruses like SARS-CoV-2.

The Technology

The technology addresses the need for rapid and accurate virus detection through Surface Enhanced Raman Spectroscopy (SERS) using a peptide-modified nanostructured metal. This technology enables the detection of a target virus by utilizing a nanostructured metal with peptides attached to its surface. These peptides have a capture portion to bind with specific portions of the target virus and enhance its Raman signal, making it easily detectable.

Commercial Applications

  1. Virus Detection: The technology can be employed for the rapid and sensitive detection of various viruses, including SARS-CoV-2, influenza viruses, and other coronaviruses.

  2. Point-of-Care Diagnostics: This technology has potential applications in point-of-care devices for immediate virus detection, enabling faster patient triage and treatment decisions.

  3. Biomedical Research: Researchers can use the technology to study viral mutations, track virus spread, and identify emerging variants in real-time.


  1. Rapid Results: The technology's use of SERS allows for quick and efficient virus detection, providing results within minutes.

  2. High Sensitivity: The peptide-modified nanostructured metal enhances the virus's Raman signal, making it highly sensitive and capable of detecting even low virus concentrations.

  3. Adaptability to Variants: The technology can be engineered to detect various virus variants by modifying the attached peptides, ensuring continued accuracy in the face of viral mutations.

  4. Ease of Use: The technology can be incorporated into user-friendly devices, making it accessible to healthcare professionals in various settings.

  5. Reduced False Negatives: Compared to antibody-based tests, this technology directly detects the virus, reducing false negative results and improving diagnostic accuracy.

The disclosed compositions, devices, methods, and systems offer a cutting-edge solution for rapid and reliable virus detection, addressing the critical need for effective diagnostic tools in combating COVID-19 and other viral outbreaks. The technology's adaptability, sensitivity, and ease of use make it a promising choice for various commercial applications and biomedical research.
