Rapid and naked-eye for colorimetric detection of morphine sulfate, using silver nanoprobe

morphine (MO) is one of the most widely used drugs in the world, and its timely and accurate identification is of particular importance[۱]. This study presents a new and simple colorimetric method for sensitive and visual detection of MO in urine using silver nanoparticles[۲]. The structure and properties of nanosensors were investigated using XRD, UV-VIS, TEM analyzes[۳] [۴]. To the best of our knowledge, this is the higher the concentration of the drug caused more discoloration[۵].The bonding interactions between the nanosensor and MO cause AgNPs to accumulate [۶], resulting in a color change from yellow to smoky, which can be detected by the naked eye [۷]. To evaluate the LOD level and quantitative measurement of MO, different concentrations of MO were prepared and analyzed with a synthesized nanosensor [۸] [۹].
