A Fiber-Optic Biosensor Based on Monooxygenases and Sol–Gel Entrapped Fluoresceinamine for Trichloroethene and Tetrachloroethene
Tetrachloroethene (a.k.a. perchloroethene, PCE) and trichloroethene (TCE) are the most frequently detected groundwater contaminants which are suspected to cause cancer in humans. Monitoring of these carcinogens suffers from high costs and inaccuracy caused by cumbersome [...]
Piezoelectric Microcantilevers of Nanoscale Thickness for Detection of Cells
This research project explores the employment of piezoelectric material as the sensing element in microcantilever beams fabricated to function as resonant mass sensors. The cantilever beam would be a very thin double-bridged structure (50 nm) [...]
Whole Cell Biosensors For (Eco)Toxicity Screening: Alternatives For The Future
As a response to the emerging environmental threats, the European Parliament introduced tough new rules for the testing and approval of thousands of chemicals. Questions are raised towards the practicality of the new legislation as [...]
Use of Magnetoresistive Biochips for Monitoring of Pathogenesis Microorganisms in Water through Bioprobes: Oligonucleotides and Antibodies
Martins V.C.B., Fonseca L.P., Ferreira H.A., Graham D.L., Freitas P.P., Cabral J.M.S., Instituto Superior Técnico, PT
Magnetoresistive biochips have been integrated with success in a microtechnology engineered set-up for the development of a portable analytical device, characterized by low-cost with high sensitivity and selectivity of immunodetection and biomolecular methods [1, 2]. [...]
A Novel Class of Sensors for System Integrative Concepts in Biotechnological Applications
Schober A., Kittler G., Kittler M., Buchheim C., Majdeddin A., Cimalla V., Fischer M., Yanev V., Himmerlich M., Krischok S., Schaefer J.A., Romanus H., Sändig T., Burgold J., Weise F., Wurmus H., Drüe K.H., Hintz M., Thust H., Gebinoga M., Kittler G., Kittler M., Spitznas A., Gottwald E., Weibezahn K-F., Wegener D., Schwienhorst A., Ambacher O., Technical University of Ilmenau, DE
The application of an system integrative approach based on hetereostructure sensors (group III nitrides) for the examination of differnt biological systems is shown and discussed.
Controlling Colorimetric Reversibility of Nanostructured Polydiacetylenes
Lee C.H., Lee J.S., Lee C.H., Lee J.S., Park H-W., Lee C.H., Lee J.S., Ahn D.J., Kim J-M, Hanyang University, KR
Polydiacetylene liposome has specific color change of blue to red upon various kinds of stimuli. Stimuli can be a antigen-antybody, thermal stimuli and Ph change and even physical contact. From these charecteristics polydiacetylene used a [...]
Electrical Detection of DNA Hybridization using Adjacent Impedance Probing (AIP) Method
Sensitivity and selectivity are two of the most challenging criteria for the development of DNA biosensor devices. These biosensor devices have attracted interest for the rapid identification of pathogens in humans, animals, and plants, for [...]
A Piezoelectric Micro-Cantilever Bio-Sensor Using the Mass-Micro-Balancing Technique with Self-Excitation
A new bio-sensor was developed in order to use in a LOC(Lab-On-a-Chip). The sensor detects the change in the resonance frequency of a micro cantilever with a piezoelectric film(PZT). This is the so-called mass micro-balancing [...]
