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