Biologicals, also known as biopharmaceuticals or biologics, are medicinal products derived from living organisms or their components, such as proteins, nucleic acids, or cells. These products are used for the prevention, treatment, or diagnosis of various diseases and conditions, and have become increasingly important in the field of medicine due to their ability to target specific molecules or pathways in the body. Biologicals can include monoclonal antibodies, vaccines, hormones, enzymes, and growth factors, among others. They are typically produced using biotechnology processes, such as genetic engineering, cell culture, or recombinant DNA technology. Research in the field of biologicals focuses on developing new and improved biologic therapies, understanding their mechanisms of action, optimizing manufacturing processes, and ensuring their safety and efficacy. This research area plays a crucial role in advancing personalized and precision medicine, as well as in providing innovative treatment options for a wide range of diseases, including cancer, autoimmune disorders, and infectious diseases.
