John H. Fenn

John H. Fenn was a scientist who, along with others, developed a method called electrospray ionization, which allows researchers to analyze large molecules like proteins and viruses without destroying them. This breakthrough enabled scientists to better understand biological molecules, significantly advancing fields like biotechnology and medicine. Fenn's work earned him the 2002 Nobel Prize in Chemistry, highlighting its importance in chemical and biological research. His contributions have helped improve drug development, disease diagnosis, and our overall understanding of complex biological systems.
