Selective π-complexation capabilities of silver(I) and copper(I) ions can be effectively facilitated in ionic liquids. To understand the effects of environmental factors that influence the π-complexation of these metal ions with analytes, techniques that employ small volumes of ionic liquid that can be readily analyzed are desired. In this study, h...

Although Qixue Shuangbu Prescription (QSP) is a classic Chinese medicine prescription for treating chronic heart failure. Low bioavailability due to the insolubility and poor biofilm permeability of the main bioactive ingredients of QSP is still a key factor limiting its efficacy. In this study, a novel self-microemulsifying drug delivery system wa...
