Electrokinetic boundary conditions are derived for ac electrokinetic phenomena over leaky dielectric (i.e., semiconducting) surfaces. Such boundary conditions correlate the electric potentials across a semiconductor-electrolyte interface (consisting of an electric double layer inside the electrolyte solution and a space charge layer inside the semiconductor) in an ac electric field with arbitra...

Delicately assembled composites of semiconducting nanomaterials and biological materials provide an attractive interface for emerging applications, such as chemical/biological sensors, wearable health monitoring devices, and therapeutic agent releasing devices. The nanostructure of composites as a channel and a sensing material plays a critical role in the performance of field effect transistor...

Printable or solution processable semiconductor materials have attracted significant attention recently due to their potential to enable cost effective, non-vacuum based fabrication approaches for large area electronics, often referred to as macroelectronics, and particularly to systems that use low cost plastic substrates. Several classes of semiconducting small molecule and polymer materials ...

The material systems include GaAs/AlGaAs semiconductor heterostructures, semiconducting nanowires and carbon nanotubes. These materials have their own advantages that can be employed to engineer a spin-friendly environment. These include fabrication and electrical-control issues as well as the strength of the hyperfine interaction (i.e. presence or absence of nuclear spins) and the spinorbit in...

Aptamers are synthetic single-stranded oligonucleotides that exhibit selective binding properties to specific targets, thereby providing a powerful basis for the development of and sensitive (bio)chemical assays. Electrochemical biosensors utilizing aptamers as biological recognition elements, namely aptasensors, at forefront current research. They exploit combination unique with advantages ele...
