We demonstrate a nonfaradaic electrochemical impedance spectroscopy measurement of biochemically modified gold plated electrodes using a two-electrode system. The absence of any redox indicator in the impedance measurements provide more precise and accurate characterization of the measured bioanalyte at molecular resolution. An equivalent electrical circuit of the electrodeelectrolyte interface...

Forward engineering synthetic circuits are at the core of biology. Automated solutions will be required to facilitate circuit design and implementation. Circuit is increasingly being automated with software, but innovations in experimental automation lagging behind. Microfluidic technologies made it possible perform vitro transcription-translation (tx-tl) reactions increasing throughput sophist...

DNA computing is an emerging field of research in which biochemistry and molecular biology elements are utilized to complete computational processes performed by traditional silicon-based technologies. Current DNA-based circuits are nonhomogenous, consisting of discrete combinatorial gates with corresponding static processing abilities. This research focuses on further developing DNA-based meth...

This paper examines the increasing police use of DNA profiling and databasing as a developing instrumentality of modern state surveillance. It briefly notes previously published work on a variety of surveillance technologies and their role in the governance of social action and social order. It then argues that there are important differences amongst the ways in which several such technologies ...

in this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of sarcheshmeh copper complex was studied. the comminution circuit of this plant includes one sag mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. the goal of this work was to calcu...

The social amoeba Dictyostelium discoideum is a commonly used eukaryotic model organism for the study of cell division, chemotaxis, differentiation, phagocytosis, and other cellular processes. Electroporation an effective efficient method delivering plasmid DNA into D. discoideum, invaluable tool studying intracellular technology readily available but often prohibitively expensive. Although sev...

methylated and un-methylated control dna is an important part of dna methylation studies. although human and mouse dna methylation control sets are commercially available, in case of methylation studies on other species such as animals, plants, and bacteria, control sets need to be prepared. in this paper a simple method of generating methylated and un-methylated control dna is described. whole...
