Problem addressed

Efficient airborne transmission of SARS-CoV-2 causes a signgificant health threat, while traditional filters (e.g. air-conditioner filter) fails to capture and inactivate the virus. This invention serves to efficiently inactivate the virus passing through the air filter.

Innovation
  • The copper filter body are coated with (111)-oriented nanotwin microstructured copper by electroplating.
  • The (111)-oriented nanotwin microstructured copper filter can efficiently inactivate respiratory viruses including SARS-CoV-2 and influenza virus.
Key impact
  • (111)-oriented nanotwin microstructured copper provides fast virus inactivation in the air filter.
  • The filter can be fabricated in a form of fibric cloth, with surface adhered with (111)-oriented nanotwin microstructured copper, providing flexibility in application.
  • Reduce the risk of airborne transmission of respiratory viruses including SARS-CoV-2 and influenza virus.
  • Protect patients and healthcare workers from hospital-acquired infections.
Application
  • Applied in air filters, including air-conditioners, air purifyers, air filtration systems.
  • Applied in the air fitration system of the hospital to reduce the risk of disease transmission.
  • Applied in the aircrafts to reduce passengers' risk of infection.
  • Applied in the HEPA filter of the biosafety cabinets to provide extra protection.

Centre for Immunology & Infection

Addressing Public Health Issues Posed by Emerging Infectious Diseases

The rise of infectious diseases poses a significant threat to human health and public health systems globally. With the objective of deepening the understanding of human response to viruses and diseases, the Centre for Immunology & Infection (C2i) will contribute to establishing Hong Kong as a global centre of excellence for precision medicine tailored to population strategies and formulate innovative solutions for public health challenges with special attention to emerging infectious diseases.

A major focus of C2i is to apply a new technology platform established by the Institut Pasteur to develop an Immune Report Card for individuals, which will help define the health of one’ s immune system — the first line defence mechanism against diseases. The work will take into consideration individual genetics, previous infection histories, resident microbiota, as well as personal lifestyle and environmental factors to come up with personalised patient management strategies and improve the effectiveness of future public health initiatives.
