Diez-Ahedo, Ruth , Normanno, Davide , Esteban, Olga,, Bakker, Gert-Jan, Figdor, Carl, Cambi, Alessandra , Garcia-Parajo, M. F., (2009). Dynamic re-organization of individual adhesion nanoclusters in living cells by ligand-patterned surfaces Small 5, (11), 1258-1263

Ligand-patterned surfaces alter the spatio-temporal organization of specific receptors on the cell membrane. Chemically confined surfaces are fabricated using microcontact patterning. The dynamic re-organization of the integrin LFA-1 in living cells is monitored at the single-molecule level using total internal reflection fluorescence. The image on the left shows individual LFA-1 nanoclusters on a single cell being recruited to ligand-rich areas of the pattern.
