From: Capture and light-induced release of antibiotics by an azo dye polymer
Antibiotic release by exposure to green light. Negative control coverslips (Control) have neither antibiotic nor DR1/PMMA. 0.625 µg tetracycline (top four rows) or 2.5 µg ampicillin (bottom four rows) was applied to the positive control coverslips (Antibiotic). 600 µg DR1/PMMA was applied to no antibiotic control coverslips (DR1/PMMA). 0.625 µg tetracycline (top four rows) or 2.5 µg ampicillin (bottom four rows), and 600 µg DR1/PMMA was applied to the experimental coverslips (DR1/PMMA + Antibiotic). See Fig. 1 to identify colonies.
