Feasibility of optical waveguide immunosensors for pesticide detection: physical aspects
The feasibility of detecting small molecules such as pesticides using optical evanescent-wave sensors is discussed with emphasis on the Mach-Zehnder sensor and a newly developed sensor called a ‘critical’ sensor. For direct detection of an estimated average pesticide layer growth of 2X 10m4 nm, the sensitivity of the Mach-Zehnder sensor is almost adequate (lx lo-” nm within one hour), whereas t...
متن کاملFeasibility of evanescent wave interferometer immunosensors for pesticide detection: chemical aspects
A waveguide Mach-Zehnder Interferometer (MZI) immunosensor has been developed which can detect, in a direct way, a minimum average layer growth thickness of the analyte of 2X 10e3 nm (bound mass, I’=lX low4 fig cm-“). The design and fabrication of the sensor and the experimental set-up are aimed at decreasing the detection limit. A flow cell has been designed and incorporated into the set-up to...
متن کاملNanoelectrochemical Immunosensors for Protein Detection
Nanoelectrochemical immunosensors fabricated by templated electrodeposition of gold nanoelectrodes inside the pores of polycarbonate (PC) track-etched membranes, followed by the immobilization of the biorecognition elements on the surrounding PC, have proven high sensitivity and specificity for protein detection. The signal transduction scheme involves a suitable redox mediator added to the sam...
متن کاملDesign of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks
This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
