A new procedure for preparing iron oxide-silica nanocomposite particles using SBA-15 mesoporous silica as a template is described. These composite materials retained the 2-D hexagonal structure of the SBA-15 template. Transmission electron micrograms of the particles depicted the formation of iron oxide nanocrystals inside the mesochannels of SBA-15 silica framework. Powder x-ray diffraction showe...

Microinjection has been demonstrated to be an effective technique to introduce foreign materials into biological cells. Despite the advance, whether cell injection can be used to characterize the mechanical properties of cells remains elusive. In this paper, extending the previously developed mechanical model, various constitutive materials are adopted to present the membrane characteristics of ce... View full abstract»

Spot segmentation-the second essential stage of cDNA microarray image analysis-constitutes a challenging process. At present, several up-to-date spot-segmentation techniques or software programs-proposed in the literature-are often characterized as “automatic.” On the contrary, they are in effect not fully automatic since they require human intervention in order to specify mandatory ...

This paper proposes a novel model for gross damage as occurring in tile-based nanomanufacturing by DNA self-assembly. Gross damage occurs due to exogenous agents (such as radiation and tip-sample interactions) and is modeled as a hole (with a large number of empty tile sites) in the aggregate of the self-assembly. A stochastic analysis based on Markov chains for the tile binding process is pursued... View full abstract»

A detailed numerical investigation concerning the influence on the electrical response of an eukaryotic cell model due to the variations of the conductivity and permittivity of the plasma and nuclear membranes is carried out by means of a vertex analysis. The dynamics of three cell performances, the voltages across the external and the nuclear membrane, and the pores density are analyzed by adopti... View full abstract»

In this paper, we consider a molecular relay channel in which signal molecules are transmitted by a sender of communication, propagated, amplified, removed in the channel, and sensed by the receiver of communication that decodes the signal molecules. To understand and characterize the communication capacity of the molecular relay channel, we develop an information communication model that consists... View full abstract»
