Specimens of Daphnia Magna were exposed to different concentrations of the drug (S,S)-2- methylamino-1-phenylpropan-1-ol (Sudafed), gold nanoparticles and a combination of them. The survival time of the species was observed to determine the effects of the treatments. Spring water was used as a control, however due to some environmental factors such as light and temperature the specimens in spring water shows a survival time of four hours 23 minutes 15 seconds (4:23:15). The gold nanoparticles was characterized using Dynamic Light Scattering (DLS) and Ultraviolet spectroscopy. Six individuals per sample were placed in the solutions. The response of the organisms varied according to the corresponding treatment. The survival time for the drug treatment was one hour 10 minutes (1:10:00), with gold nanoparticle 58 minutes (00:58:00) and the last treatment was two hours 35 minutes 20 seconds (2:35:20). This data shows that the interaction of the drug with the gold nanoparticles enhanced the survival time of these specimens in comparison to the other treatments. Further studies are needed to explore the reaction of drug and the nanoparticle.
