Tremendous research efforts have been devoted to fabricating high quality quantum dots (QDs) for applications in biology and medicine. Much of this research was pursued with an ultimate goal of using QDs in clinical applications. However, a great deal of concern has been voiced about the potential hazards of QDs due to their heavy-metal content. Many studies have demonstrated toxicity of variou...

Nanobiotechnology in agriculture is a driver for modern-day smart, efficient agricultural practices. Nanoparticles have been shown to stimulate plant growth and disease resistance. The goal of sustainable farming can be accomplished by developing sustainably exploiting the fruits nanobiotechnology balance advantages nanotechnology provides tackling environmental challenges. This review aims adv...

The rapid developments in nanotechnology have brought with them a deep concern over the safety of nanomaterials. Investigating the molecular mechanisms underlying their toxicity in different cell lines will help us better understand and apply nanomaterials appropriately. Poly(ethylene glycol)-phosphoethanolamine (PEG-PE) is an FDA-approved nonionic diblock copolymer and is widely used in drug d...

Superoxide dismutase (SOD) is the first line of defense against oxidative damage. Malathion an organophosphate insecticide and can induce production reactive oxygen species (ROS) cause intracellular stress. The present study was undertaken to examine effects malathion on SODs activity their transcriptional levels in Oxya chinensis (Thunberg) (Orthoptera: Acrididae). results showed that total SO...
