Photo-luminescent carbon dots (CD) have become promising nanomaterials and their synthesis from natural products has attracted attention by the possibility of making most affordable, sustainable and, readily-available sources. Here, we report on synthesis, characterization bioimaging potential CDs produced diverse extensively fruits: kiwi, avocado pear. The in vitro cytotoxicity anticancer those were assessed comparing human epithelial cells normal adult kidney colorectal adenocarcinoma...
Titanium dioxide (TiO2) and silver (Ag) NPs are among the most used engineered inorganic nanoparticles (NPs); however, their potential effects to marine demersal fish species, not fully understood. Therefore, this study aimed assess proteomic alterations induced by sub-lethal concentrations citrate-coated 25 nm ("P25") TiO2 or polyvinylpyrrolidone (PVP) coated 15 Ag turbot, Scophthalmus maximus. Juvenile were exposed through daily feeding for 14 days. The tested 0, 0.75 1.5 mg of each per kg...
The extensive use of nanomaterials, including titanium dioxide nanoparticles (TiO2 NPs), raises concerns about their persistence in ecosystems. Protecting aquatic ecosystems and ensuring healthy safe aquaculture products requires the assessment potential impacts NPs on organisms. Here, we study effects a sublethal concentration citrate-coated TiO2 two different primary sizes over time flatfish turbot, Scophthalmus maximus (Linnaeus, 1758). Bioaccumulation, histology gene expression were...
Abstract A bioaccumulation study in red ( Palmaria palmata ) and green Ulva sp.) seaweed has been carried out after exposure to different concentrations of citrate-coated titanium dioxide nanoparticles (5 25 nm) for 28 days. The concentration total the number size accumulated seaweeds determined throughout by inductively coupled plasma mass spectrometry (ICP-MS) single particle-ICP-MS (SP-ICP-MS), respectively. Ammonia was used as a reaction gas minimize effect interferences 48 Ti...
The current research deals with the use of single-cell inductively coupled plasma-mass spectrometry (scICP-MS) for assessment titanium dioxide nanoparticle (TiO
The biological response to nanomaterials exposure depends on their properties, route of exposure, or model organism. Titanium dioxide nanoparticles (TiO2 NPs) are among the most used nanomaterials; however, concerns related oxidative stress and metabolic effects resulting from ingestion rising. Therefore, in present work, we addressed citrate-coated 45 nm TiO2 NPs combining bioaccumulation, tissue ultrastructure, proteomics approaches gilthead seabream, Sparus aurata Japanese carpet shell,...
Antimony tin oxide (Sb2O5/SnO2) is effective in the absorption of infrared radiation for applications, such as skylights. As a nanoparticle (NP), it can be incorporated into films or sheets providing attenuation while allowing transparent final product. The acute toxicity exerted by commercial Sb2O5/SnO2 (ATO) NPs was studied adults and embryos zebrafish (Danio rerio). Our results suggest that these do not induce an zebrafish, either embryos. However, some sub-lethal parameters were altered:...
Nanomaterials significantly contribute to the development of new solutions improve consumer products properties. Silver nanoparticles (AgNPs) are one most used, and as human exposure such NPs increases, there is a growing need for analytical methods identify quantify present in environment. Here we designed detection strategy AgNPs seawater using surface-enhanced Raman Scattering (SERS). Three commercial coated with polyvinylpyrrolidone (PVP) were used determine relative impact size...
Seaweeds are recognised as a potential eco-friendly food source. However, some species have shown the capacity to bioaccumulate many substances of diverse nature, such inorganic nanoparticles (NPs), which may potentially harmful effects on them. Among these NPs, silver (AgNPs) been used enhance antifungal and antibacterial properties final consumer products, textiles packages. Their release into aquatic environment raises significant concern, increasing probability interaction with biota,...
