  • Concept of hybrid molecules: When double strand DNA is steamed to a temperature exceed the melting temperature (Tm), it will separate into 2 single strands DNA due to breaks of H bonds. If the reaction temperature is then decreased slowly plus other appropriate experimental conditions, these ssDNA will pair again. This phenomenon is called the hybridization of molecules. Characteristic of the hybrid molecules: Specificity, the re-pairing occurs only between two complementary sequences.

  • This book presents basic and advanced principles underlying the multivalent interactions that are prevalent in biological systems. To illustrate important or complex concepts, the book provides up-to-date examples of synthetic multivalent molecules, their design, and their biological benefits. Functional roles displayed by such molecules of both natural and synthetic origin are well documented in biology, where they exert unique and crucial activities at a level not readily achievable by monovalent molecules.

  • Molecules, small structures composed of atoms, are essential substances for lives. However, we didn’t have the clear answer to the following questions until the 1920s: why molecules can exist in stable as rigid networks between atoms, and why molecules can change into different types of molecules. The most important event for solving the puzzles is the discovery of the quantum mechanics. Quantum mechanics is the theory for small particles such as electrons and nuclei, and was applied to hydrogen molecule by Heitler and London at 1927.

  • Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles.[1] The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.

  • This course of lectures is devoted to protein physics, i.e., to the overall topics of structure, self-organization and function of protein molecules. The course is based on lectures given by us (earlier by O.B.P., and later by A.V.F.) first at Moscow PhysTech Institute and then at Pushchino State University and the Pushchino Branch of MoscowState University. Initially, our students were physicists, then mainly biologists with some chemists.

  • There is hardly any book that aims at solving problems typically encountered in the laser field, and this book intends to fill the void. Following some initial exercises related to general aspects in laser physics (Chapt. I), the subsequent problems are organized along the following topics: (i) Interaction of radiation with matter either made of atoms or ions, weakly interacting with surrounding species, or made of more complicated elements such as molecules or semiconductors (Chapters 2 and 3). (ii) Wave propagation in optical media and optical resonators (Chapters 4 and 5)....

  • Twenty-five years ago, Georges Köhler and César Milstein invented a means of cloning individual antibodies, thus opening up the way for tremendous advances in the fields of cell biology and clinical diagnostics (1). However, in spite of their early promise, monoclonal antibodies (MAbs) were largely unsuccessful as therapeutic reagents resulting from insufficient activation of human effector functions and immune reactions against proteins of murine origin.
