Donald Tomalia
Donald A. Tomalia (born September 5, 1938) is an American chemist who is known as one of the early discoverers of dendrimers. Biography Tomalia earned an undergraduate degree from the University of Michigan, a master's degree from Bucknell University and a Ph.D. in physical organic chemistry from Michigan State University. He worked at Dow Chemical for many years as a research scientist then moved to the Michigan Molecular Institute as a Senior Lead Scientist. In 1979, Tomalia first reported on the synthesis of dendrimers, which have been used in nanotechnology and pharmaceuticals. The first dendrimer synthesis was noted by winning the Leonardo da Vinci Prize (Paris, 1996). In 1990, he joined the Michigan Molecular Institute (MMI) as Professor and Director of Nanoscale Chemistry &Architecture (1990–1999). In 1992, Tomalia founded his own company, Dendritech. The company was purchased by Dow Chemical a few years later. Tomalia was the scientific director of the Center for Biolog ...

Dendrimer
Dendrimers are highly ordered, Branching (polymer chemistry), branched molecules, polymeric molecules. Synonymous terms for dendrimer include arborols and cascade molecules. Typically, dendrimers are symmetric about the core, and often adopt a spherical three-dimensional morphology. The word dendron is also encountered frequently. A dendron usually contains a single chemically addressable group called the focal point or core. The difference between dendrons and dendrimers is illustrated in the top figure, but the terms are typically encountered interchangeably. The first dendrimers were made by #Divergent methods, divergent synthesis approaches by Fritz Vögtle in 1978, R.G. Denkewalter at Allied Corporation in 1981, Donald Tomalia at Dow Chemical in 1983 and in 1985, and by George R. Newkome in 1985. In 1990 a #Convergent methods, convergent synthetic approach was introduced by Craig Hawker and Jean Fréchet. Dendrimer popularity then greatly increased, resulting in more tha ...

The University of Michigan Medicine (branded as Michigan Medicine) is the academic medical center of the University of Michigan, a public research university in Ann Arbor, Michigan. It consists of the university's Medical School, affiliated hospitals, and affiliated healthcare centers. History In 1869 the University of Michigan opened the first hospital in the country owned and operated by a university, in a house in Ann Arbor originally built as a professor's residence. In 1876 a new hospital building was opened adjacent to the old one.
