Cell is the structural and functional unit of life. This Resource Letter serves as a guide to the literature on nano-machines which drive not only intracellular movements, but also motility of the cell. These machines are usually proteins or macromolecular assemblies which require appropriate fuel for their operations. Although, traditionally, these machines were subjects of investigation in bi...

This article examines the cognitive evolution and disciplinary diversity of nanoscience/nanotechnology (nano research) as expressed through the terminology used in titles of nano journal articles. The analysis is based on the NanoBank bibliographic database of 287,106 nano articles published between 1981 and 2004. We perform multifaceted analyses of title words, focusing on 100 most frequent wo...

based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

BACKGROUND Development of Haemoglobin-based oxygen carriers (HBOCs) as blood substitutes has reached an impasse due to clinically adverse outcomes attributed to vasoconstriction secondary to nitric oxide (NO) scavenging. Studies suggest haemoglobin exhibits nitrite reductase activity that generates NO and N(2)O(3); harnessing this property may offset NO scavenging. Therefore, the effects of con...

the 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicatesand 10 eggs per each replicate. treatments including: (t1; control; without injection), (t2; injected with 0.3ml saline 9.0%; sham control), (t3, t4 and t5) 25, 75, 125 ppm fe-nano, (t6, t7 and t8) 50, 100, 150 ppmfe-nano-alimet chelate, (t9, t10 and t11) 50, 100, 150 ppm fe-aliment chela...

using titanium dioxide nano-silver packaging, which is antibacterial and resistance to the diffusion of gases such as oxygen, is increasing in food industry. therefore, we compared the effect of titanium dioxide-based nano-silver packaging and conventional polyethylene packaging on the fungal flora of consuming bread in order to increase the shelf-life storage of consuming bread. one hundred fo...

nano-sized drugs have better distribution than their identical forms. magnesium is the cofactor of various enzymes in lipid and glucose metabolism. in this study the effect of nano-magnesium oxide (nano-mgo) on glucose concentration and lipid profile in diabetes induced mice was evaluated in 21 laboratory mice. mice were divided randomly into three equal groups (control, treatment and placebo)....

Scutellariabaicalensis (SB) is a traditional Chinese medicine for treating infectious and inflammatory diseases. Our recent study shows potent antibacterial effects of nanoparticle-encapsulated chlorhexidine (Nano-CHX). Herein, we explored the synergistic effects of the nanoparticle-encapsulated SB (Nano-SB) and Nano-CHX on oral bacterial biofilms. Loading efficiency of Nano-SB was determined b...

Summary The potential environmental and health impacts of nano-technologies triggered a recent surge of life cycle assessment (LCA) studies on nano-technologies. Focusing on the energy use and greenhouse gas emissions impacts, we reviewed 22 LCA-based studies on nano-materials, coatings, photovoltaic devices, and fabrication technologies that were published until 2011. The rev...

As knowledge of the structure and function of nucleic acid molecules has increased, sequence-specific DNA detection has gained increased importance. DNA biosensors based on nucleic acid hybridization have been actively developed because of their specificity, speed, portability, and low cost. Recently, there has been considerable interest in using nano-materials for DNA biosensors. Because of th...
