The present invention provides a method and device that substantially increases reverse iontophoretic flux and therefore, noninvasive extraction of uncharged and charged permeant molecules alike through the skin. By substituting the mobile co-ions, which are capable of easily entering the pores from the receiver compartment of a reverse iontophoretic extraction device with large conductive polyelectrolytes within the reservoir that do not appreciably enter the pores, the invention significantly improves the amount of analyte extracted, improves device performance, decreases energy requirements, increases battery life, reduces the potential for irritation, and improves accuracy, reproducibility, and precision.
本发明提供了一种方法和装置,可大幅提高反向离子渗透通量,从而实现通过皮肤无创提取不带电和带电的渗透分子。本发明用储液器中不会明显进入毛孔的大分子导电聚电解质取代了容易从反向离子渗透萃取装置的接收器舱进入毛孔的移动共离子,从而显著提高了分析物的萃取量,改善了装置性能,降低了能量要求,延长了电池寿命,减少了潜在的刺激性,并提高了准确性、再现性和精确度。
