متن کاملNanotoxicology: a personal perspective.
Nanoparticles arise from a wide variety of natural and man-made sources and have a diverse array of biological, chemical, and physical properties. The toxicity of these particles can be roughly divided into two categories: 1) the enhanced delivery of toxic agents 2) toxicity induced the properties of the particle itself. The use of nanoparticles to provide enhanced delivery of chemotherapeutics...

378 nature nanotechnology | VOL 3 | JULY 2008 | www.nature.com/naturenanotechnology oxygen vacancies. In the latter case, the actual carriers are lattice ions, which are much heavier than electrons. The scaling characteristics of these metal–oxide–metal devices are not discussed by the HP team, but they should, in principle, be quite good because the oxygen vacancies will probably have to drift...
متن کاملNanotechnology, nanotoxicology, and neuroscience.
Nanotechnology, which deals with features as small as a 1 billionth of a meter, began to enter into mainstream physical sciences and engineering some 20 years ago. Recent applications of nanoscience include the use of nanoscale materials in electronics, catalysis, and biomedical research. Among these applications, strong interest has been shown to biological processes such as blood coagulation ...
متن کاملNanotoxicology: nanoparticles reconstruct lipids.
news & views a n emerging 'rule of thumb' suggests that nanoparticles less than 100 nm in diameter can enter cells, those with diameters below 40 nm can enter the cell nucleus and those that are smaller than 35 nm can pass through the blood–brain barrier and enter the brain. Understanding the way nanoparticles interact with living matter will open up fundamentally new opportunities in medicine ...
