Fig. 16. A performance comparison was conducted with the commercially available COVID-19 antigen kit. The quantum dot-based COVID-19 antigen kit was able to accurately measure concentrations as low as 0.8875 × 10 TCID50/mL, whereas the commercial gold nanoparticle-based kit could measure concentrations up to 3.55 × 102 TCID50/mL. Based on these results, it can be inferred that the quantum dot-based antigen kit is effective in measuring lower concentrations compared to the commercially available kit.
