This volume investigates the theory of the effect of static electric fields on one-electron states in. nanocylindrical and nanospherical heterolayers and quantized semiconductor films.

Homogeneous external electrostatic field for all these structures has been considered as a "universal" modulating factor. For structures with radial symmetry, a study on the influence of radial static field and the electric field of a charged ring on one-electron states is presented. Chapters focusing on homogeneous field effect on low-dimensional excitonic states in the quantized films and quantum wires - in both wide bandgap and narrowband semiconductors - are also included. Other contents include calculations weak, moderate and strong electric fields, quantum-mechanical approximation and perturbation theory, the quasi-classical approximation (WKB method). Readers will benefit from the varied methodological to the subject which gives them a concrete analytical framework to solve problems related to nanoscale semiconductor design. The reference should prove to be useful to academics and professionals working in semiconductor nanoelectronics research and development.

A biosensor is an integrated receptor-transducer device that converts a biological response into an electrical signal. The design and development of biosensors have taken center stage for researchers or scientists in the recent decade owing to the wide range of biosensor applications in healthcare and disease diagnosis, environmental monitoring, water and food quality, and drug delivery. Due to their adaptability, ease of use in relatively complex samples, and portability, the significance of electrochemical biosensors in analytical chemistry has increased manifold. Electrochemistry has been pivotal in developing transduction methods for biological processes and biosensors. In parallel, the explosion of activity in nanoscience and nanotechnology and their huge success have profoundly affected biosensor technology, opening new avenues of research for electrode materials and transduction.

Electrochemical Biosensors in Practice: Material and Methods particularly explores the use of silver and gold nanoparticles for signal amplification, photocurrent transduction, and aptamer design. Therefore, the book serves as an introductory text for those specializing in biosensors and bioelectronics and their practical applications.
