In this work, we present new results about the non-enzymatic detection of lindane by using CuO-MnO2 hierarchical nano-microstructures. The linear range for the determination of lindane is up to 700 μM with a limit of detection of 4.8 nM, which is much lower than for other non-enzymatic lindane sensors.

The purpose of this paper is to connect two critical aspects of nano-composite materials engineering. The nano-elements considered here derive from the class of high aspect ratio nematic polymers, either rod-like or platelet spheroids. First, the overall electrical properties of polymer nano-composites are well approximated by the effective electrical conductivity tensor in the low volume fract...

We propose the nano-scale displacement sensor with high resolution for weak-force systems could be realized based on vertical stacked two-dimensional (2D) atomic corrugated layer materials bound through Van der Waals (VdW) interaction. Using first-principles calculations, we found the electronic structure of bi-layer blue phosphorus (BLBP) varies appreciably to both the lateral and vertical int...

Human noroviruses are the dominant cause of outbreaks of acute gastroenteritis. These viruses are usually detected by molecular methods, including reverse transcriptase PCR (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). Human noroviruses are genetically and antigenically diverse, with two main genogroups that are further subdivided into over 40 different genotypes. During the past deca...

Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.

objectives: maintaining pulp vitality is a main goal in restorative dentistry. introduction of pulp capping agents paved the way to eliminate the shortcomings of these materials and obtain successful restorations. on the other hand, nanotechnology is an emerging field of science with increasing use in dental materials. this study sought to assess the effect of addition of nano-tio2, nano-sio2 a...

block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. in this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. the factor fphil is defined as the ratio of the number of hydroph...
