Summary: This study evaluated the antibiotic response patterns observed in liquid samples from E. coli under different conditions and found that the experimental procedure significantly impacts the resulting SERS signals. The target patterns could only be observed when the bacteria were washed with water and incubated with antibiotics in a nutrient-rich growth medium. These findings can improve existing methods for testing antibiotic responses using SERS.
