background and purpose: in people wearing dentures, the growth of various candida species under the prosthesis leads to the formation of biofilm, which can play the role of a reservoir for candida and other kinds of microbes. since nano-chitosan particles can cause lasting antimicrobial activity, a more recent approach that utilizes acrylic resins with nano-chitosan particles is proposed. there...

nano technology has a large number of applications in different fields of science and technology. nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. the properties of nanoparticles depend largely on their synthesis procedures. there are different methods for the synthesis of nano particles using different conditions. in ...

Selenium has many roles on the functioning of humans and animals. Chicks as animal model can play an important role to distinguish the role/function of selenium. The objective of the present study was to test the effect of variable doses of nano-selenium supplement on the chicken gastrointestinal tract. A total of 180 male Ross chicks were divided into six groups, with three replicates for each...

background and aims. incorporation of nano-particles to orthodontic bonding systems has been considered to prevent enamel demineralization around appliances. this study investigated cytotoxicity of transbond xt adhesive containing 1 wt% titanium dioxide (tio2) nano-particles. materials and methods. ten composite disks were prepared from each of the conventional and tio2-containg composites and ...

magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. the most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (mri) and heating mediators for cancer therapy. in...

The aim of this study was to evaluate the effects of nano-particle of selenium on liver antioxidant activity, blood cells count and IgG level in rats exposed to oxidative stress. Twenty four male rats were randomly divided into four treatments with six replicates. Treatments included of: control group gavaged and injected (ip) normal saline; T1: injected (ip) tert butyl hydroperoxide (t-BHP) at...

The effect of nano selenium foliar application on some secondary metabolites Hypericum perforatum L.

Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...
