摘要: Novel membrane-free chemically modified polystyrene microspheres for the optical detection of sulphate in aqueous media are introduced. The working principle this sensor is based on surface mass-extraction equilibrium target species. This allows overcoming strong hydration energy penalty, a typical problem divalent anions. exhibits both enhanced sensitivity and selectivity, which accurate biological samples. To illustrate these features determination urine presented.
