FT electron spectroscopy studies of electron absorption and transfer show an efficiency of above 99%, which cannot be explained by classical mechanical models like the diffusion model. Various structures, such as the FMO complex in green sulfur bacteria, are responsible for transferring energy from antennae to a reaction site. The energy collected in reaction sites must be transferred quickly before it is lost to fluorescence or thermal vibrational motion. Photosynthesis creates Frenkel excitons, which provide a separation of charge that cells convert into usable chemical energy. For example, bacteria use ring-like antennae, while plants use chlorophyll pigments to absorb photons. Organisms that undergo photosynthesis absorb light energy through the process of electron excitation in antennae. The excitation then transfers through various proteins in the FMO complex to the reaction center to further photosynthesis. Applications Photosynthesis ĭiagram of FMO complex. In 1979, the Soviet and Ukrainian physicist Alexander Davydov published the first textbook on quantum biology entitled Biology and Quantum Mechanics. In his paper, he stated that there is a new field of study called "quantum biology". In 1963, Per-Olov Löwdin published proton tunneling as another mechanism for DNA mutation. Other pioneers Niels Bohr, Pascual Jordan, and Max Delbrück argued that the quantum idea of complementarity was fundamental to the life sciences. He further suggested that mutations are introduced by "quantum leaps". Schrödinger introduced the idea of an " aperiodic crystal" that contained genetic information in its configuration of covalent chemical bonds. Erwin Schrödinger's 1944 book What Is Life? discussed applications of quantum mechanics in biology. Early pioneers of quantum physics saw applications of quantum mechanics in biological problems. It has been suggested that quantum biology might play a critical role in the future of the medical world. Though the field has only recently received an influx of attention, it has been conceptualized by physicists throughout the 20th century. Quantum biology is an emerging field, in the sense that most current research is theoretical and subject to questions that require further experimentation. Quantum biology is concerned with the influence of non-trivial quantum phenomena, which can be explained by reducing the biological process to fundamental physics, although these effects are difficult to study and can be speculative. Quantum biology may use computations to model biological interactions in light of quantum mechanical effects. Such processes involve chemical reactions, light absorption, formation of excited electronic states, transfer of excitation energy, and the transfer of electrons and protons ( hydrogen ions) in chemical processes, such as photosynthesis, olfaction and cellular respiration. Many biological processes involve the conversion of energy into forms that are usable for chemical transformations, and are quantum mechanical in nature. An understanding of fundamental quantum interactions is important because they determine the properties of the next level of organization in biological systems. Quantum biology is the study of applications of quantum mechanics and theoretical chemistry to aspects of biology that cannot be accurately described by the classical laws of physics.

Herein, we summarize recent findings on the hydration of synthetic polymers, supramolecular materials, inorganic materials, proteins, and lipid membranes. Analysis of the water states of hydrated materials is complicated and remains controversial however, knowledge about interfacial water is useful for the design and development of advanced biomaterials. Biomolecules are important for understanding the interactions and biological reactions of biomedical materials to elucidate the role of hydration in biomedical materials and their interaction partners. The amount and degree of denaturation of adsorbed proteins affect subsequent cell behavior, including cell adhesion, migration, proliferation, and differentiation. When biomedical materials come into contact with body fluids, the first reaction that occurs on the material surface is hydration proteins are then adsorbed and denatured on the hydrated material surface.
