TL;DR: Critical determinants that can affect the generation of ROS include size, shape, particle surface, surface positive charges, surface-containing groups, particle dissolution, metal ion release from nanometals and nanometal oxides, UV light activation, aggregation, mode of interaction with cells, inflammation, and pH of the medium.

TL;DR: The development of nonlinear optical materials has been driven by a multitude of important technological applications that can be realized if suitable materials are available, and future generations of optoelectronic devices for telecommunications, information storage, optical switching, and signal processing are predicted to a large degree on the development of materials with exceptional NLO responses.

TL;DR: The experimental results show that TNT can be detected quickly and accurately without any dye tagging in lower pM level with excellent discrimination against other nitro compounds and heavy metals.

TL;DR: This review summarizes recent advances, particularly the molecular mechanism of nanosilver toxicity, which causes oxidative stress through the generation of reactive oxygen species and causes damage to cellular components.

TL;DR: A critical evaluation of challenges and future needs for the safe environmental nanotechnology are discussed and a summary of recent research efforts on fate, behavior, and toxicity of different classes of nanomaterials in the environment is presented.
