Nanoparticles (NPs) have been widely used in medical and therapeuticapplications. However, their albumin binding and their cytotoxicity assays havenot been well explored. In his study, the interaction of NiO NPs with human serumalbumin (HSA) was explored by circular dichroism (CD) study, molecular dockingand dynamic studies. Afterwards the cytotoxicity of NiO NPs against...

The attention on CeO2-NPs environmental and in vivo effects is due to their presence in diesel exhaust and in diesel filters that release a more water-soluble form of ceria NPs, as well as to their use for medical applications. In this work, acute and subacute in vivo toxicity assays demonstrate no lethal effect of these NPs. Anyhow, performing in vivo evaluations on CD-1 mouse systems, we demo...

Carbon dots (CDs) have many fascinating fluorescent properties, however, their low quantum yield limits their applications. In this study, the photoluminescence (PL) of CDs in the vicinity of gold nanoparticles (Au NPs) is enhanced significantly due to the surface plasmon resonance (SPR) of the Au NPs. This is achieved by conjugating Au NPs and CDs to dendrimers (PAMAM) through an amidation rea...

A novel injectable and high-solid-content drug-loaded supramolecular hydrogel (PTX-mPECT NP/α-CDgel) was prepared by self-assembly of inclusion complexes based on PTX-loaded mPECT (methoxy poly(ethylene glycol)-b-poly(ε-caprolactone-co-1,4,8-trioxa[4.6]spiro-9-un-decanone)) nanoparticles (PTX-mPECT NPs) and α-cyclodextrin (α-CD). Paclitaxel (PTX) was chosen as a hydrophobic drug encapsulated in...

The vast application of fluorescent semiconductor nanoparticles (NPs) or quantum dots (QDs) has prompted the development of new, cheap and safer methods that allow generating QDs with improved biocompatibility. In this context, green or biological QDs production represents a still unexplored area. This work reports the intracellular CdTe QDs biosynthesis in bacteria. Escherichia coli overexpres...

Iron oxide nanoparticles (NPs) are commonly utilized for biomedical, industrial, and commercial applications due to their unique properties and potential biocompatibility. However, little is known about how exposure to iron oxide NPs may affect susceptible populations such as pregnant women and developing fetuses. To examine the influence of NP surface-charge and dose on the developmental toxic...

Core-shell silica-coated Fe(0) nanoparticles (Fe@SiO2) were prepared in one-step synthesis by aqueous reduction combined with modified Stöber method. The as-prepared Fe@SiO2 were then used for simultaneous removal of Cr(VI) and Cd(II) from aqueous solution. Batch tests indicated that Fe@SiO2 exhibited high removal capacity toward Cr(VI) and Cd(II). Cr(VI) was removed by Fe@SiO2 through reductio...

Abstract Background Cadmium (Cd) is amongst the most toxic heavy metals that severely affects crop growth, whereas application of nanoparticles (NPs) to negate effects could be an effective management approach. In present study, seeds two fragrant rice varieties i.e., Yuxiangyouzhan and Xiangyaxiangzhan under normal Cd stress conditions 0 100 mg L ? 1 applied with four levels ZnO NPs 0, 25, 50,...

Chemical synthesis of Ag-NPs was carried out using reduction method. The reduction mechanistic approach of silver ions was found to be a basic clue for the formation of the Ag-NPs. The nanoparticles were characterized by UV-vis, FT-IR and TEM analysis. We had designed some experiments in support of our hypothesis, "low concentrations of novel nanoparticles (silver and gold) increases the activi...
