Aggregation-induced emission fluorogens as biomarkers to assess the viability of microalgae in aquatic ecosystems.
نویسندگان
چکیده
Microalgae can be a valuable indicator for monitoring water pollution due to their sensitivity to the changes induced by pollutants in the environment. In this study, an aggregation-induced emission fluorogen was used as a novel tool to differentiate dead and live microalgae and quantify the link between live algal concentration and fluorogen intensity. Protein in the cell protoplasm is the key component contributing to fluorescence emission in algae.

Toxicity Effect of Colloidal Silver Nanoparticles to Marine Microalgae, Nannochloropsis oculata
To assess the acute toxicity of colloidal silver nanoparticles (AgNPs) in Nannochloropsis oculata, microalgal cells were exposed to different concentrations of AgNPs for 72 hours and according to OECD 201. Algal cell count was done every 24 hours and average specific growth rate, as well as percent inhibition of the average specific growth rate, were calculated for each concentration. Also, the...
متن کاملOrganelle-specific bioprobes based on fluorogens with aggregation-induced emission (AIE) characteristics.
Bioprobes based on fluorogens with aggregation-induced emission (AIE) characteristics have been increasingly used in chemosensing and bioimaging due to their high sensitivity, photostability and biocompatibility. In this review, we summarize the design of cellular organelle specific (cytoplasm membrane, mitochondria, lysosomes, lipid droplets and nucleus) AIE bioprobes and their applications in...

In the present study, half maximal effective concentration (EC50) of the Linear Alkylbenzene Sulfonate on microalgae Nannochloropsis oculata were investigated. The experiment was carried out with seven treatments (six main treatments and one control) with three replications in 25 ºC and pH of 6.9 for 72 hours on July 2017. The concentration of linear alkyl benzene sulfonate in first to six trea...

Phytoplankton is one of the main components of wetlands, which plays a vital role in providing nutrients, oxygen for other organisms, stabilizing nitrogen and carbon dioxide. In the meantime, the current status of Lake Urmia highlights the need to conserve and protect wetlands related to these ecosystems and their living and non-living components. Therefore, this study was conducted to assist i...
متن کاملInvestigating the effect of different concentrations of heavy metal of cadmium on the green microalgae of Chlorella sp.
Heavy metal pollution in aquatic ecosystems affects microalgae and zooplankton, alters the biomass and abundance of species, and promotes interspecies relationships to the predominance of less sensitive species. In this study, the effect of short-term stress of different concentrations of cadmium heavy metal on Chlorella sp. growth and some biochemical parameters have been investigated. Microal...
