Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.).

Langmuir, 2010
We have developed a new model of nanoparticle adhesion which explicitly takes into account the change in the nanoparticle surface energy. Using combination of the molecular dynamics simulations and theoretical calculations we have showed that the deformation of the adsorbed nanoparticles is a function of the dimensionless parameter beta proportional ...

AbstractHuman exposure to nanoparticles is inevitable as nanoparticles become more widely used and, as a result, nanotoxicology research is now gaining attention. However, while the number of nanoparticle types and applications continues to increase, studies to characterize their effects after exposure and to address their potential toxicity are few in

Current Opinion in Chemical Biology, 2003
This review covers the emerging field of nanobiotechnology, in which nanoparticles are applied to the analysis of biomolecules. Nanoparticles can be used in a variety of bioanalytical formats, and this review discusses four classes of use. First, nanoparticles as quantitation tags, such as the optical detection of quantum dots and the electrochemical ...

Dental Materials, 2017
Nanoparticles having a size from 1 to 100nm are present in nature and are successfully used in many products of daily life. Nanoparticles are also embedded per se or as byproducts from milling processes of larger filler particles in many dental materials.Recently, possible adverse effects of nanoparticles have gained increased interest with the lungs ...

Malignant melanoma is one of the most common causes of cancer and cancer deaths in young people. Until few years ago, scarce drugs have proven efficacy in metastatic setting. However, in the recent years, the treatment of metastatic malignant melanoma has undergone the incorporation of effective treatment such as immunotherapy, the use of tyrosine ...

Radiosensitization and Nanoparticles
2015Nanomaterials have been shown to have physical and chemical properties that have opened new avenues for cancer diagnosis and therapy. Nanoconstructs that enhance existing treatments for cancer, such as radiation therapy, are being explored in several different ways. Two general paths toward nanomaterial-enabled radiosensitization have been explored: (1)

Currently, gelatin nanoparticles are gaining more grounds in drug and gene delivery throughout all the available several routes of administration. Yet, the homogenous and less disperse preparation of this type of nanoparticles is still a challenging task due to the variation of the gelatin quality according to its source and due to its variable ...

Wetting of nanoparticles and nanoparticle arrays
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002Abstract We report investigations of nanoparticulate wetting carried out using molecular dynamics simulations. Despite their small size, model ‘Lennard–Jones’ nanoparticles in simple Lennard–Jones solvents exhibit well defined contact angles, which for high surface tension interfaces have been shown to obey Young's equation with surprising accuracy ...
