Viruses are submicroscopic, subcellular agents that cannot replicate outside of a host cell. They can infect all living things, including birds, bacteria, reptiles, mammals, protozoa, insects, plants, fungi, and fish. Virology refers to the scientific study of the biology of viruses and viral diseases, comprising their evolution, physiology, biochemistry, clinical aspects, molecular biology, distribution, and ecology. Due to their small size, viruses are considered to be naturally occurring nanoparticles. The usage of viruses for biomedical purposes is studied under the field of viral nanotechnology. Viruses are used within this field as vectors for gene delivery, immunotherapy and vaccination. Bacteriophages are a type of viruses which are used extensively for medical purposes. These viruses infect and kill bacteria without harming human cells. This book unravels the recent studies in the field of viral nanotechnology. It is a valuable compilation of topics, ranging from the basic to the most complex advancements in this field. This book will prove to be immensely beneficial to students and researchers in the field of viral nanotechnology.
