Lanthanide coordination polymers have been recently regarded as attractive sensing materials because of their selectivity, high sensitivity, and rapid response ability. In this research, the multiporous terbium phosphonate polymer microspheres (TbP-CPs) were prepared a novel fluorescent probe, which showed fluorescence turn-on capability for detection trace anthrax biomarker dipicolinate acid (DPA). The morphology chemical composition as-prepared TbP-CPs characterized in detail. vegetable-flower-like structure microporous surface. addition, not only possess merits convenience simple preparation with yield but also excellent characters probes, such stability, good ability within 30 s. This proposed sensor could detect DPA linear relationship concentrations ranging from 0 to 8.0 μM sensitivity 5.0 nM. Furthermore, successful applications urine bovine serum demonstrated. As result, recovery ranged 93.93–101.6%, relative standard deviations (RSD) less than 5%.
