The total flow time of an hourglass is depending on the effective diameter of the neck pipe if the amount of sand is fixed. Molecularly imprinted polymers (MIPs) can recognize the targets with high selectivity. In this study, these characters had been combined together and applied to develop a sensor using a simple timer as readout for the first time. Hydroxy polychlorinated biphenyls (OH-PCBs) had been chosen as the model target. If the MIPs had bounded with the OH-PCBs, the imprinting cavity of the MIPs can be blocked by the target, and the effective pore diameter of the column decreased. When the 25 ppb OH-PCBs was adsorbed, the average pore size of the MIPs decreased from 1.4614 nm to 1.3964 nm, and the pore volume decreased from 0.001928 cm3/g to 0.001697 cm3/g. As a result, the total time needed for the complete outflow of a certain amount of water increased accordingly. The total time had a relationship with OH-PCBs concentration in the range of 1.0 to 100 ppb, and the detection limit was as low as 0.3 ppb. The proposed technique has been successfully applied for the detection of 4′-OH-PCB 30 in the environmental samples. The detection of different targets could be easily achieved by simply changing MIPs of different imprints.
