An ultrasensitive multiplexed electrochemical immunoassay method was developed for the detection of tumor markers by combining a newly designed trace tag and a disposable immunosensor array. The array was prepared by immobilizing capture antibodies on gold nanoparticles which were assembled on carbon nanotubes-chitosan modified screen-printed carbon electrodes. The trace tag was prepared by loa...

We present the self-assembled formation of nanosized PFDTS (1H,1H,2H,2H-perfluorodecyltrichlorosilane) features on multilayered silica sphere arrays. We reveal the importance of residual water within the microsphere multilayers during PFDTS deposition and discuss a possible mechanism for the formation of the siloxane nanostructures. The multiscaled roughness induced by these superstructures is ...

Cernik, A. A. (1970). Brit. J. industr. Med., 27, 40-42. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid. A method is described for the determination of lead in whole blood containing ethylenediaminetetra-acetic acid. Proteins were precipitated by 2-0 M perchloric acid. The ionized lead in the supernatant was chel...

The efficient detection of charged biomolecules by biosensor with appropriate semiconducting nanomaterials and with optimum device geometry has caught tremendous research interest in the present decade. Here, the performance of various label-free electronic biosensors to detect bio-molecules is investigated by simulation technique. Silicon nanowire sensor, nanosphere sensor and double gate fiel...

Large-scale atomistic simulations considering a 5 nm in radius H-passivated Si nanosphere that impacts with relatively low energies onto a H-passivated Si substrate reveal a transition between two fundamental collision modes. At impacting speeds of less than 1000 m /s particle-reflection dominates. At increased speeds the partial onset in the nanosphere of a -tin phase on the approach followed ...

Recent advances in the use of plasmonic metamaterials to improve absorption of light in thin-film solar photovoltaic devices has created a demand for a scalable method of patterning large areas with metal nanostructures deposited in an ordered array. This article describes two methods of fabricating ordered 2D nanosphere colloidal films: spin coating and interface coating. The two methods are c...

The impact of spherical symmetry breaking and crystallinity on the response of the vibrational acoustic modes of a nanoobject in frequency- and time-domain experiments is investigated using the finite-element analysis method. The results show that introduction of shape anisotropy, i.e., evolution from a nanosphere to a nanorod, modifies the periods of the fundamental radial and quadrupolar mode...

A Bloch point singularity can form a metastable state in a magnetic nanosphere. We classify possible types of Bloch points and analytically derive the shape of the magnetization distribution for different Bloch points. We show that an external gradient field can stabilize the Bloch point: The shape of the Bloch point becomes radially dependent. We compute the magnetization structure of the nano...
