SUMMARY:Active surfaces with tunable adhesion - Dr. Aránzazu del Campo\, 
 Max-Planck-Institut für Metallforschung
DTSTART:20080122T120000Z

UID:TALK10311@talks.cam.ac.uk
CONTACT:Dr James Bendall
DESCRIPTION:The interaction between two bodies in close proximity is stron
 gly influenced by the chemical nature of their outmost molecular layer and
  their surface topography. The external control of these factors enables f
 ine tuning of the resulting adhesion forces. Particular interesting are su
 rface designs which enable strong but reversible attachment\, or even sele
 ctive adhesion. Biology provides spectacular examples which inspire our de
 velopments\, eg. the hierarchical assembly of nanosized setae found in gec
 ko’s feet which enable their effective locomotion\, or the selective att
 achment or cells to surfaces with particular topographies and compositions
 . Artificial realisation of such properties requires the combination of ma
 terials and surface chemistry with micro and nanofabrication techniques to
  obtain complex and responsive surface designs. Novel developments based o
 n wavelength sensitive materials and complex 3D topographies will be prese
 nted. These will allow us to control adhesion phenomena at different level
 s in multiple fields of modern technologies.\nhttp://www.mf.mpg.de/en/abte
