The shock resistibility of MEMS device has been an urgent issue in the field of consumer electronics, automotive industry and special military applications. The paper analyses experimentally the shock resistibility of a typical MEMS capacitive [...]

Using Electron Tunneling for Direct Sequencing of DNA

Dong J., Lund J., Mehta R., Parviz B.A., Rahimi M., Ryan D., University of Washington, US

Genomic information has assumed a central role in the way biology in general and cell function in particular are understood today. Methods that can sequence DNA rapidly, accurately, and cost-effectively are needed in order to [...]

Nanoelectrodes with Selective Molecular Receptors for Label-Free Electronic Detection of Thrombin

Dong J., Parviz B.A., University of Washington, US

The enzyme thrombin plays a crucial role in the regulation of blood coagulation. We present a sensor that can directly detect this enzyme and generate an electronic signal. The sensor structure consists of three electrodes [...]

Tracking the Formation of a Break Junction Formed by Electromigration using Transmission Electron Microscopy

Dong J., Parviz B.A., University of Washington, US

Break junctions formed by electromigration have been extensively used in the molecular electronics and electrical characterization of atomic or molecular clusters and biological molecules such as deoxyribonucleic acid (DNA)1. However, to obtain a controllable gap [...]
