Response of highly sensitive SnO2 semiconductor carbon monoxide (CO) gas sensors based on target gas CO quasi-molecular-imprinting mechanism design is investigated with gas concentrations varied from 50 to 3000 ppm. SnO2 nanoparticles prepared via hydrothermal method and gas sensor film devices SC (exposed to the target gas CO for 12 h after the suspension coating of SnO2 film to be fully dried...

Imprinting disorder during somatic cell nuclear transfer usually leads to the abnormality of cloned animals and low cloning efficiency. However, little is known about the role of donor cell imprinting in the development of cloned embryos. Here, we demonstrated that the imprinting (H19/Igf2) in porcine fetus fibroblasts derived from the morphologically abnormal cloned fetuses (the abnormal impri...

An ultrathin novel nanosensor (31.5 +/- 4.1 nm thick in the absence of analytes), employing a molecularly imprinted polymer as a recognition element for cholesterol and gold nanoparticle enhanced transmission surface plasmon resonance spectroscopy for detection, was constructed.

We discuss the use of subdivision surfaces in the procedural design of imprint rolls for use in the roller imprinting process. Roller imprinting is being developed for the fabrication of microfluidic devices in polymer substrates. Imprint rolls are modeled using Catmull-Clark subdivision surfaces, and are procedurally designed based on feedback from finite-element simulations of the imprinting ...

In this study, Zn(NO3)2·6H2O was selected as the metal source, and ZIF-7-modified magnetic graphene-based matrix materials (MRGO@ZIF-7) were prepared by in situ growth. ZIF-7 modified molecular imprinting complexes (MRGO@ZIF7-MIP) successfully synthesized a surface technique using bisphenol A (BPA) template molecule. The obtained experimental characterized X-ray diffraction (XRD), Brunner–Emmet...

4-chloro-2-methylphenoxy acetic acid (mcpa) is one of the most important pesticides which is extensively used to control weeds in arable farmland. exposure to this compound occurs in general population and persons who occupationally handle it. the aim of this present work was the preparation of mcpa imprinting polymer and its application as a selective sample preparation technique for trace det...

The review article focuses ‘Molecular Imprinting’ a multidisciplinary material view from the window of past trends to present’s and future’s road map. This is a first critical 'review of reviews' that covers the field from laboratory research to advanced material science in industrial applications. The article gives insight into ideas in the perspectives of step by step past trends, practical d...

A highly efficient soil-burrowing dung beetle possesses an intricate outer contour curve on its foreleg end-tooth. This study was carried out based on evidence that this special outer contour curve has the potential of reducing soil penetration resistance and could enhance soil-burrowing efficiency. A toothed wheel is a typical agricultural implement for soil imprinting, to increase its working...
