Timothy Manning Swager (born July 1, 1961 in Sheridan ) is an American chemist, known for the development of chemical sensors based on conductive polymers and carbon nanotubes .

Swager studied chemistry at Montana State University with a bachelor's degree in 1983 (with top grades) and received his doctorate in 1988 with Robert H. Grubbs at Caltech ( Precursor routes to conducting polymers from the ring-opening metathesis polymerization of cyclic olefins ). He was a post-doctoral student at the Massachusetts Institute of Technology (MIT) with Mark S. Wrighton . In 1990 he became Assistant Professor and in 1996 Professor at the University of Pennsylvania and in 1996 he became a full professor at MIT. From 2005 to 2010 he headed the chemistry faculty there. Since 2005 he has been the John D. MacArthur Professor of Chemistry at MIT. From 2002 to 2005 he was deputy director of the Institute for Soldier Nanotechnologies.

Swager developed novel chemical sensors based on molecular electronics (nanowires and molecular wires with conductive polymers). This enabled him to develop sensors for the detection of explosives, which were marketed under the name Fido (ICx Technologies). Fido was based on amplification by fluorescent polymers (AFP, amplified fluorescent polymer) and the name should be reminiscent of a dog (the sensitivity is comparable to highly trained explosive dogs). Fido won the US Army Greatest Invention Award twice and is used, for example, in portable devices and robots. Further detectors were developed at his laboratory based on functionalized carbon nanotubes (C2Sense, founded by his doctoral student Jan Schnorr). They are also used to detect chemical substances (with application, for example, to the freshness of food).

Swager also conducted research on liquid crystals and developed interlocking molecular structures for high-strength materials, developed functionalized graphenes and carbon nanotubes, and novel materials for use in NMR (with Robert G. Griffin, marketed in his company DyNuPol Corp.) that could be used as additives with dynamic nuclear polarization improve the signal-to-noise ratio.

He is involved in more than 39 patents. He is the founder of Iptyx Corporation (2003 to 2009, high performance polymers) and of Dynupol in 2009.

Swager received the Linus Pauling Award in 2016 and the Lemelson MIT Prize in 2007 . In 2019 he received the ACS Award in Polymer Chemistry , 2016 the Gustavus John Esselen Award, 2012 the Centenary Prize of the Royal Society of Chemistry , 2005 the Carl S. Marvel Creative Polymer Chemistry Award and the Christopher Columbus Foundation Homeland Security Award and 2013 the Award for Creative Invention of the American Chemical Society . In 2000 he was a Cope Scholar. In 2006 he received an honorary doctorate from Montana State University. He is a member of the American Academy of Arts and Sciences and the National Academy of Sciences . He was a Sloan Research Fellow from 1994 to 1996 and received the DuPont Young Faculty Award from 1993 to 1996.
