DNA-Functionalized Carbon Nanotube Chemical Sensors

The group of Professor Charlie Johnson has developed chemical sensors using single-walled carbon nanotubes wrapped with single-stranded DNA adsorbed to the nanotube's outer wall.

Euclid Mission to Explore Dark Energy

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures.  Penn researchers are part of the Euclid science team.


Dark Energy Studies

Professor Masao Sako uses Type Ia supernovae to study the expansion history of the universe.  The graphs show (left and middle) Hubble diagrams from a simulated 5-year Type Ia sample from the Dark Energy Survey.  The right graph shows the 95% confidence limits on dark energy parameters.
