Cortisol is a steroid hormone that regulates wide range of vital processes. Its level changes with diurnal rhythm and reacts to stress. Measurement cortisol levels still complex multi-step process. A reversible washing-free registration method required. Here we describe metal-enhanced fluorescence assay based on displacement dye labeled BSA-cortisol conjugate from the immune immobilized golden ...

In this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. Bohemite (Aluminum oxyhydroxide) was prepared as a precursor by strict control of pH and reaction temperature. The gel produced was purified by washing fol...
