What are Self-Sterilizing Polymers?

Image Credit: Kriengsak tarasri/Shutterstock.com The ability to inactivate pathogens on contact by using inherently biocidal surfaces is at the core of some of the latest strategies for controlling the spread of harmful microorganisms in the healthcare industry, public transportation, and other sectors with a high risk of pathogen transmission via contaminated surfaces. Today, infectious diseases are the second leading cause of death globally, surpassed only by heart diseases. Traditionally, the most common strategies to mitigate disease-causing agents spread are based on chemical disinfectants (such as bleach, hydrogen peroxide, and detergents) or repeated exposure to radiation (UV light). However, both approaches can damage the treated surface, adversely affect the environment, or introduce additional health concerns.

New study tests how mutations in SARS-CoV-2 affect antibody neutralization

New study tests how mutations in SARS-CoV-2 affect antibody neutralization Using pseudoviruses with single amino acid substitutions, researchers found that mutations in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reduce monoclonal antibody neutralization differently. However, convalescent sera samples did not lose neutralization potency many and were also effective against the B.1.1.7 (UK-derived) strain. As SARS-CoV-2 continues to infect people around the world, it is also mutating. The majority of the mutations are on the virus spike protein, the key viral component that binds to host cells and the main antigenic target for vaccines and antivirals. Since many vaccines, and antibodies from a previous infection, are based on the earlier circulating strains, it is unknown how immunity will be affected by the new strains.
