This was an illustration I made for Prof. Jamie Spangler and co. (Johns Hopkins University). Our illustration was chosen to be a supplementary cover of the weekly edition (Volume 144 Issue 25 June 29, 2022).
Description: Rapid, cost-effective, and widely available diagnostics are needed to monitor and mitigate the spread of SARS-CoV-2 and future outbreaks. An engineered antibody–enzyme fusion protein (blue) recognizes human antibodies (red) and catalyzes the conversion of sucrose (pink) to glucose (magenta), allowing quantification of antibodies against disease antigens (yellow) using commercial glucometers.
