This book provides a selection of recent developments in scanning ion conductance microscopy (SICM) technology and applications. In recent years, SICM has been applied in an ever-increasing number of areas in the bioanalytical sciences. SICM is based on an electrolyte-filled nanopipette with a nanometer-scale opening, over which an electric potential is applied. The induced ion current is measured, which allows to directly or indirectly quantify various physical quantities such as pipette-sample distance, ion concentration, sample elastic modulus among many others. This makes SICM well suited for applications in electrolytes - most prominently for the study of live cells.This book starts with a historic overview starting from the days of the invention of SICM by Paul Hansma at the University of California at Santa Barbara in 1989. SICM is a member of the family of scanning probe microscopies. It is related to another prominent member of the family, atomic force microscopy (AFM), which has found application in almost any field of nanoscale science. The advantages and disadvantages of SICM over AFM are also outlined. One of the most effective and break-through applications of SICM nanopipettes is in electrochemistry. The different routes and applications for doing electrochemistry using nanopipettes are also discussed. In addition the book highlights the ability of SICM for surface positioning with nanometer precision to open up new vistas in patch clamp measurements subcellular structures. Finally the book presents one research area where SICM has been making a lot of contributions, cardiac research and the endeavors to combine SICM with super-resolution optical microscopy for highest-resolution joint topography and functional imaging.

Radiobiology is a field of medical science that studies the action of ionizing radiation on biological tissues and their cellular and molecular components. Ionizing radiation can cause severe harmful impacts in living beings but it can also provide health benefits for treating cancer and thyrotoxicosis through radiation therapy. Ionizing subatomic particles can be classified into five types, namely, alpha particles, beta particles, positrons, gamma rays and X-rays. The most common impact of ionizing radiation is that it may induce cancer with a latent period of years or decades after exposure. The administration of high doses of ionizing radiation can cause visually dramatic radiation burns and may prove fatal due to acute radiation syndrome. Therefore, controlled doses of ionizing radiation are administered for medical imaging and radiotherapy. There are four factors that determine the success or failure of standard clinical radiation treatment. These factors include repair of DNA damage, redistribution of cells in the cell cycle, repopulation, and reoxygenation of hypoxic tumor areas. This book contains some path-breaking studies in the field of radiobiology. Scientists and students actively engaged in the study of ionizing radiation will find it full of crucial and unexplored concepts.
