Microfabricated PCR-electrochemical device for simultaneous DNA amplification and detection.
Microfabricated silicon/glass-based devices with functionalities of simultaneous polymerase chain reaction (PCR) target amplification and sequence-specific electrochemical (EC) detection have been successfully developed. The microchip-based device has a reaction chamber (volume of 8 microl) formed in a silicon substrate sealed by bonding to a glass substrate. Electrode materials such as gold an...
متن کاملμ-eLCR: a microfabricated device for electrochemical detection of DNA base changes in breast cancer cell lines.
Microfabricated devices for the electrochemical detection of single DNA base changes in cancer cell lines are highly desirable due to the inherent advantages such as portability, simplicity, and the rapid and inexpensive nature of electrochemical readout methods. Moreover, molecular sensors that use microscale-footprint working electrodes have shown high signal-to-noise ratio. Herein we report ...
متن کاملFully integrated on-chip electrochemical detection for capillary electrophoresis in a microfabricated device.
Microfabricated lab-on-a-chip devices employing a fully integrated electrochemical (EC) detection system have been developed and evaluated. Both capillary electrophoresis (CE) channels and all CE/EC electrodes were incorporated directly onto glass substrates via traditional microfabrication techniques, including photolithographic patterning, wet chemical etching, DC sputtering, and thermal wafe...
متن کاملAdvancement in electrochemical DNA-biosensors for GMOs detection: A review
Genetically modified organisms (GMOs) are plants or animals whose genetic make-up has been transformed by recombinant DNA technology, which has new features such as resistance to herbicides, virus and insect. Recently, genetic modification of food products has increased in order to reduce world poverty and hunger and increase food production However, the impact of GMOs on the human health is a ...
متن کاملAn Efficient Method For DNA Extraction From Paraffin Wax Embedded Tissues For PCR Amplification Of Human And Viral DNA
Background and Objective: Formalin-fixed paraffin-embedded tissues are a valuable source of DNA for molecular studies. We designed and optimized an efficient procedure for DNA extraction from formalin-fixed paraffin embedded tissues. Materials and Methods: Seventy three blocks of cervical paraffin-embedded tissues were investigated. DNA was extracted using 45 minutes boiling in alkaline sol...
