چکیده
User-friendly devices for detecting low gliadin content in commercial foods are of extreme importance people with gluten diseases. With this concern, the present work proposes a rapid and sensitive optical nanostructured microarrays platform detection using specific anti-gliadin IgG antibodies immobilized on annealed gold nanostructures (AuNPs) obtained after high annealing process (550 °C) thin films evaporated glass coverslips. Localized Surface Plasmon Resonance (LSPR) immunosensing range 0.1 ppm to 1000 is successfully achieved. In addition, biofunctionalization protocol was used screening five food complex products.

Algorithms for large-scale genotyping microarrays
MOTIVATION Analysis of many thousands of single nucleotide polymorphisms (SNPs) across whole genome is crucial to efficiently map disease genes and understanding susceptibility to diseases, drug efficacy and side effects for different populations and individuals. High density oligonucleotide microarrays provide the possibility for such analysis with reasonable cost. Such analysis requires accur...
متن کاملUltra-sensitive immunoassay biosensors using hybrid plasmonic-biosilica nanostructured materials.
We experimentally demonstrate an ultra-sensitive immunoassay biosensor using diatom biosilica with self-assembled plasmonic nanoparticles. As the nature-created photonic crystal structures, diatoms have been adopted to enhance surface plasmon resonances of metal nanoparticles on the surfaces of diatom frustules and to increase the sensitivity of surface-enhanced Raman scattering (SERS). In this...
متن کاملTraces of molecular disease mechanisms on microarrays
The main roads of statistical microarray data analysis currently include data normalization, multiple testing, classification models, clustering algorithms and graphical models of transcriptional networks. In this paper we describe two side roads. In the first chapter we describe a semi-supervised algorithm for molecular diagnosis, which is designed for the diagnosis of complex molecular phenot...
متن کاملA TWO-STAGE METHOD FOR DAMAGE DETECTION OF LARGE-SCALE STRUCTURES
A novel two-stage algorithm for detection of damages in large-scale structures under static loads is presented. The technique utilizes the vector of response change (VRC) and sensitivities of responses with respect to the elemental damage parameters (RSEs). It is shown that VRC approximately lies in the subspace spanned by RSEs corresponding to the damaged elements. The property is leveraged in...
متن کاملMining Traces of Large Scale Systems
Large scale distributed computing infrastructure captures the use of high number of nodes, poor communication performance and continously varying resources that are not available at any time. In this paper, we focus on the different tools available for mining traces of the activities of such aforementioned architecture. In this paper we propose new techniques for fast management of a frequent i...
