Introduction To Biophysics

Science is divided into different disciplines – Biology, Physics, Chemistry, etc. All these are again incomplete without the contribution of mathematics. A separate study of nature and natural phenomenon through specified fields of biology, physics, mathematics, and chemistry gave us a certain idea about them. But with time it was realized to understand the real world, we need to combine all the knowledge of different fields to get a unified view. Only a unified view can bring us closer to the real world. This led to the development of many multidisciplinary as well as an interdisciplinary field of studies, like astrophysics, biophysics, physical chemistry, biochemistry, astrobiology, biomechanics, biopsychology, etc.

Biophysics or biological physics combines physics with biology. It is an interdisciplinary field of science which is a congruence of many other disciplines. Major contributing disciplines are physics, mathematics, chemistry, engineering, pharmacology, material sciences, and computer science. All these together are utilized to define the biological systems, phenomena, and functioning.

The concept of biophysics might have been around many centuries and can be traced back as early as ancient Romans and Greeks. Discovery of radioactive elements and inventions related to those elements like nuclear weapons shifted focus to the effect of radiation on living organisms. Research in this aspect widened the view of biology by utilizing physics to explain the mechanics of life. This new approach seeks to explain the life at the molecular level – molecular composition of biomolecules, cells, organization, and hierarchy, how they from molecules to cells to tissues to organs to organ system to organism work.

Life At The Molecular Level

Living organisms are comprised of basic elements like Carbon, Hydrogen, Oxygen, Nitrogen, Sulphur, Phosphorous, etc. All these combine in a different manner to give rise to the basic biomolecules – proteins, carbohydrates, lipids, and nucleic acids. They help to create the unit of life the cell. Though diverse in their shape, size, composition, and properties, they function as the building blocks of life creating cells, tissues, organs, organ systems and finally the entire organism.

The major functions allocated to basic macromolecules are as follows:

1. Nucleic acids store the information required for the cell functioning are known as genetic material.
2. Lipids create the membranous boundaries which help to compartmentalize the cell from the rest of the surrounding and even creates sub-compartments inside the cell which help in work distribution.
3. Carbohydrates used as energy source and storage and are part of many structural and functional components of the cell in association with proteins or lipids.
4. Proteins are the working machinery of cells in the form of enzymes and take part as a major structural component.

All these macromolecules interact among each other and with other molecules, ions for the sustenance of life. The underlying mechanisms involved in a molecular association like association and dissociation kinetics, energetics, thermodynamics, and molecular dynamics, special organization, stability, ionization, wave-particle interaction, etc. can be studied by biophysics. Using diversified tools and analytical methods, the intricacies of biological functions at cellular can be explained in terms of structure, function, and properties of specific molecules. Even it is possible to develop tools for detection, and manipulation of a single molecule.

Biophysics can also integrate the cellular working mechanism at the higher levels of organ and organism, helping to unravel the body’s functioning. These functions can be visualized using different biophysical techniques and even modeled. Modelling and simulation are successfully used for prediction and therapeutics. Moreover, the biophysical study of environment and organisms also sheds light on the ecological interactions around us on earth.

Applications of Biophysics

Being an interdisciplinary science, it can be applied in multiple domains. Some of them have been mentioned below:

1. Structure and Data Analysis – The structure of many biological macromolecules like DNA, RNA and proteins have been elucidated till date. Techniques of purification, characterization, sequencing, and crystallization has helped in this process. Presently innumerable entries are available for DNA, RNA, and protein sequences from varieties of living organisms. These entries have been utilized for the structural analysis, sequence matching, development of gene maps, and evolution and phylogenetics. Species relatedness, developmental hierarchy, and diversification can be studied extensively.

2. Modelling – Biophysics also deals with computation, using which models can be developed for DNA, RNA, protein, and viruses, etc. This approach helps in better visualization of the desired object and understanding the working process. A complete understanding is essential for further manipulation of structure and prediction of the consequences. Thus, gives an in-depth understanding of the effect of mutations, DNA damage or any other abnormality due to conditions like disease or cancer. Moreover, the foremost application of modeling so far has been done in drug designing and finding new drug targets.

3. Molecules Dynamics – Molecular dynamics can also be studied under biophysics. This has been accomplished by using fluorescent tags which can bind to specific target inside or outside the cells. The fluorescence can be monitored using spectroscopy or microscopy techniques and thus the movement of molecules could be recorded. It has immense scope in predicting the working machinery of cells like the dynamics of the plasma membrane during endocytosis, exocytosis, signaling, transportation, assembly, and disassembly of cytoskeleton during the cell cycle, sudden rise and fall of internal signals in form of ions, cAMP etc. and even outside the cell movement of secretory signals viz. hormones from one cell to another.

4. Neuroscience – Another active area where biophysics has been extensively used is in understanding the nervous system. Nowadays famous Deep learning in computation is based on Neural Networks – single layer, multilayer – an algorithm which is modeled based on the human brain. The neural network recognizes patterns by interpretation of sensory data through a kind of machine perception viz. labeling or clustering raw input. Likewise, to understand the working of the brain and nervous system during processing of different sensory information like visual, auditory, etc. models have been developed using neural networks.

5. Nanotechnology and Biomedical engineering – The critical understanding of mechanics of an organ and its supportive tissues helps in the development of biomimetics. The detailed knowledge and simulations provide an extra edge to design appropriate biomaterials and to improve upon it which can replace the damaged tissues or organs like prosthetic limbs. Even the development of better nanomaterials as a drug delivery system is also possible through biophysical studies.

6. Imaging – Development of sophisticated imaging techniques like CT scans, MRI, US, and PET scans have been possible by biophysical studies. These types of imaging and diagnostic tools are essential for efficient, precise, rapid and safe diagnosis and monitoring of organs and bioprocesses.

7. Medical Therapeutics- Biophysicist also work towards research and development of therapeutic devices, which can be successfully utilized to treat certain conditions. Some of such devices and techniques so far developed and being utilized include a pacemaker, stents, cardiac defibrillators, artificial joints – knee and hip, dialysis, electrotherapy, radiation therapy, etc.

8. Ecosystem study– Biophysics also studies life from a larger view of environment and population, community, so considering both aspects of abiotic and biotic factors. A detailed study of all these along with model development is essential for understanding the ecosystem, its variations and complexities, dynamics, conservation, and management.
