Electroacoustic miniaturized DNA-biosensor.
A micrometer-sized electroacoustic DNA-biosensor was developed. The device included a thin semi-crystalline polyethylene terephthalate (PET) dielectric layer with two Ag microband electrodes on one side and a DNA thiol-labeled monolayer adsorbed on a gold surface on the other. A resonance wave was observed at 29 MHz with a network analyzer, upon AC voltage application between the two Ag electro...

متن کاملA Readout Chip for Miniaturized in Vivo Biosensor Implant
This work presents a programmable read-out chip for a miniaturized multi-parameter in vivo biosensor implant. The chip stimulates the measurement electrodes and reads out the generated analog signals in order to carry out temperature, pH and oxygen measurements. The design process aims at the optimization of the chip programmability and energy efficiency so as to make it suitable for implantabl...
متن کاملMiniaturized fiber-optic biosensor to monitor asparagine in clinical samples
Asparagine biosensor was constructed by co-immobilized anti-leukemic enzyme (L-asparaginase) and absorptive pH sensitive indicator on to plastic chips of 5mm through hydro sol-gel approach. Asparagine is used as a biomarker for detection of acute lymphoblastic leukemia. In this research work asparagine biosensor was developed focusing on L-asparaginase activity as bioassay principle. L-asparagi...
متن کاملElectroacoustic polymer microchip as an alternative to quartz crystal microbalance for biosensor development.
Laser photoablation of poly(ethylene terephthalate) (PET), a flexible dielectric organic polymer, was used to design an acoustic miniaturized DNA biosensor. The microchip device includes a 100-microm-thick PET layer, with two microband electrodes patterned in photoablated microchannels on one side and a depressed photoablated disk decorated by gold sputtered layer on the other side. Upon applic...
