The very dynamic growth of nanotechnology, nanomaterials (sized 1-100 nm) and their medical applications over the past 10 years has promised to add a new impetus to the diagnostics and therapeutics of a wide range of human pathologies, including cancer, cardiovascular diseases and diseases of the central nervous system. This growth in nanomedicine also fuels advances in bioengineering, regenera...
Nanoparticle in vivo characteristics and interactions between nanoparticles and organisms are key components of nanotoxicology. 1H NMR was used to analyze rat urine metabolites exposed to TiO, nanopartcles by intratracheal instillation in low (0.8 mg/kg), medium (4 mg/kg) and high doses (20 mg/kg). Significant metabolite (Acetate, Valine, Dimethylamine, Taurine, Hippurate, and 2-Oxoglutarate) c...
With the advancement of nanotoxicology and nanomedicine, it has been realized that nanoparticles (NPs) interact readily with biomolecular species and other chemical and organic matter to result in biocorona formation. The field of the environmental health and safety of nanotechnology, or NanoEHS, is currently lacking significant molecular-resolution data, and we set out to characterize biocoron...
The development and implementation of nanomaterials (NMs) is rapid and a vast range of applications is already in place or foreseen. Consequently, there is a concomitant increased likelihood for NMs being released into the environment. Given this, there is concern regarding the potential ecological sustainability of nanotechnology [1]. Although, this concern has driven an impressive progress in...
Photodynamic therapy (PDT) uses the combination of non-toxic dyes and harmless visible light to produce reactive oxygen species that can kill cancer cells and infectious microorganisms. Due to the tendency of most photosensitizers (PS) to be poorly soluble and to form nonphotoactive aggregates, drug-delivery vehicles have become of high importance. The nanotechnology revolution has provided man...
