A method to manipulate the position and orientation of submicron particles nondestructively would be an incredibly useful tool for basic biological research. Perhaps the most widely used physical force to achieve noninvasive manipulation of small particles has been dielectrophoresis(DEP). However, DEP on its own lacks the versatility and precision that are desired when manipulating cells since it is traditionally done with stationary electrodes. Read More

Despite the fact that the marine crustacean Artemia salina is extensively used in ecotoxicology, there is still a lack of information about its sensitivity to commonly used chemicals. In the presented study, acute toxicity of 18 commonly used chemicals - including organic solvents, industrial chemicals, metals and inorganic compounds - to A. salina was evaluated. Read More

Gold nanoparticles, like single fluorophores, can be used to locate single molecules with nanometer accuracy. Unlike an optical trap, the gold particle label does not exert an external load, which is important for studying diffusive processes. Thus, a gold particle can be used analogously to a single fluorophore, providing similar information but with submillisecond time resolution. Read More

As a result of evidence of the ecotoxicity of nitrofurans, the acute toxicity of furazolidone was tested in vivo on two aquatic organisms, Artemia salina and Daphnia magna, which are both crustaceans. Toxicity studies were also performed on larvae of Culex pipiens molestus. Results indicated a significant toxicity of the compound on Culex pipiens and Daphnia magna, while Artemia salina proved to be the least sensitive. Read More
