With the development of molecular biology and genetic technology, target DNA detection and transition of genetic information are becoming increasingly significant, and electrochemical biosensor gains many concerns in direct detection of target DNA due to the advantages, i.e. simple mechanism, reliable result, low-cost process, sensitive and selective method for genetic detection. a novel biosensing...
This paper reports new neural probe schemes incorporating various optical waveguides for optogenetic applications. A photodefinable polymer (SU-8) has been patterned to form optical mixer and splitter waveguides for advanced optical functions with multiple light sources and easy delivery of light to multiple shanks, respectively. Also, multiple stimulation sites have been implemented by step-wise...
We demonstrate that the efficiency of DNA hybridization could be improved by introducing elevated temperature in the hot region and higher velocities in the cold region of a microfluidic chip. Compared with the conventional methods, this hybridization microchip was shown to increase the hybridization signal 4.6-fold within 30 minutes using a 1.4 kb target DNA as the test material. The increase in...
Novel electrochemiluminescence (ECL) nanoprobe was constructed, and the high sensitivity afforded by the current ECL assay based on ECL nanoprobe without the PCR amplification of telomerase reaction products.
We have fabricated a silicon microprobe integrated with a nanometer-sized light emitting diode (Nano-LED) on the tip. This paper describes the fabrication procedure and preliminary topographic testing results. The silicon probe with electrode pattern was made by wet-etching a silicon-on-insulator wafer using oxide as the mask. Subsequently, the probe tip was cut using a focused ion beam (FIB) to form...
In this paper, we report an in-situ nanosoldering technique to make electrically conductive interconnections between three-dimensional (3D) helical micro-/nanostructures and electrodes for the nanorobotic assembly of nanoelectromechanical systems (NEMS) using gold nanoparticle ink. 3D helical nanobelts are placed onto pre-fabricated gold electrodes using nanorobotic manipulation inside a scanning...
In recent years, quartz crystal microbalance (QCM) plays an important role in many biological detections, and the enhancement of a single strain DNA probe linked to the sensor surface is of crucial importance in DNA molecule recognition. By means of nanogold modification and mass amplification, a QCM biosensor for Escherichia coli O157:H7 DNA detection was explored and developed in this work. As a...
