context_page_description: Mostafa A. El-Sayed is a highly cited Egyptian chemical physicist, a leading nanoscience researcher, a member of the National Academy of Sciences and a US National Medal of Science laureate. He is also known for the spectroscopy rule named after him, the El-Sayed rule.
context_section_description: El-Sayed and his research group have contributed to many important areas of physical and materials chemistry research. El-Sayed's research interests include the use of steady-state and ultra fast laser spectroscopy to understand relaxation, transport and conversion of energy in molecules, in solids, in photosynthetic systems, semiconductor quantum dots and metal nanostructures. The El-Sayed group has also been involved in the development of new techniques such as magnetophotonic selection, picosecond Raman spectroscopy and phosphorescence microwave double resonance spectroscopy. A major focus of his lab is currently on the optical and chemical properties of noble metal nanoparticles and their applications in nanocatalysis, nanophotonics and nanomedicine. His lab is known for the development of the gold nanorod technology. El-Sayed has over 500 publications in refereed journals in the areas of spectroscopy, molecular dynamics and nanoscience.
  El Sayed's son, Ivan El-Sayed, the Professor of Head and Neck Oncologic Surgery at the University of California, took part in applying these outcomes on cancerous cells of some animals.Cancer Lett. 2008 Sep 28; 269(1): 57–66.
