    Basic principles of impedance spectroscopy
    (CRC Press, 2023) Bhatt, Geeta
    Impedance spectroscopy of biomolecules is a growing domain that deals with the study and analysis of various analyte molecules to express high-utility applications. The analytes can be directly extracted from the environment or are derived from nature through some biological/biochemical processes. The common biological analytes are drugs, DNA/RNA, cells, pathogenic bacteria, enzymes, ions, and gases. Impedance analysis measures the impedance characteristics of an analyte over a long-range frequency sweep and interprets its behavior for various frequency domains. This detection method can be utilized for analysis in an independent or integrated format with various discrete analysis/supporting techniques. Along with extensive application in the biomedical field, this technique is also used in several other applications like the analysis of electroactive polymer thin films, colloids, lubricants, paints, and batteries/fuel cells. This chapter explains the utility of impedance analysis through a detailed explanation of fundamental principles, its several components, equivalent circuit diagrams, and their common applications.

    DNA-Based Sensors
    (Springer, 2017-12) Bhatt, Geeta
    Sensing and detection for clinical diagnostic can be accomplished through various routes. Additionally what and how of sensing is critically optimized to meet individual needs. Diagnostics is carried out with various types of sensors out of which the electrochemical sensors are most used due to their unique ability to couple seamlessly with electronic circuitry. The DNA sensor is one of the most common types of sensors which is majorly deployed to perform expression monitoring, transcription profiling, etc., for example, the products developed by Affymetrix and Nanogen. This chapter is a consolidated review of the various aspects of DNA sensors, like the principle of detection, various ways of sensing and detection, applications of such DNA-based sensing. It looks at the various principles that are utilized for gene mapping like dielectrophoresis, polymerase chain reaction (PCR), real-time PCR or quantitative PCR (better known as q-PCR), hybridization, solid-phase PCR, droplet-based PCR, etc. It also reviews various sensing/detection strategies for sensing DNA like electrophoresis, impedance spectroscopy, colorimetric sensing, optical sensing and inertial sensing. The chapter provides a state-of-the-art review of basic techniques, sensing methodologies and applications for DNA-based diagnostics as carried out by industry.
