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.

Nanotech Gene Sequencing

Prof. Marija Drndic is researching a technique to sequence genes by reading DNA bases as they translocate through a silicon nitride nanopore.  As strands of DNA in a salt solution are driven through the pore by an applied electric field, the electric current passing through changes with the size of the base.  This method could be essential for swift sequencing of genes and personalized medicine.

MRSEC Research at Penn

The P&A department plays a large role in the Laboratory for Research on the Structure of Matter (LRSM). One focus of LRSM research between faculty from different departments and schools is soft matter and how it conforms, assembles, and reconfigures in response to the geometry and chemistry of bounding surfaces and interfaces.
