Figure 1. Low-cost synthesis of citrate-based fluorescent sensors.

Figure 1

(A) One-pot synthesis scheme of biodegradable photoluminescent polymers (BPLPs), and isolation of CA-Cysteine as the chloride recognition element. Chloride sensitivity is observable in a cuvette as drops of NaCl completely quenches the blue fluorescence of CA-Cysteine. (B) Facile synthesis scheme of citric acid and various primary amines to expand the family of citrate-based halide sensors with versatile halide sensitivities.
