An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

A cost-effective ratiometric biosensor was developed for on-site detection of Escherichia coli (E. coli) using readily available l-tryptophan (l-trp) and levofloxacin. The detection was based on the degradation of the enzyme tryptophanase in E. coli toward l-trp and its fluorescence quenching of levofloxacin. The biosensor achieves the integrated effect of bacteria detection and sterilization. The detection and quantification limit were 102–158 and 308–442 cfu mL⁻¹, respectively. The feasibility of the method was validated by analyzing fruit juice, green tea, blueberry peels, and lettuce leaves samples with recoveries from 96.1% to 106.3%. Moreover, a self-designed portable device was constructed.
