The properties of holes in metallic film of subwavelength
sizes have been an object of interrest for diffraction theory
since the 1940s and more recently experimentally studied[1].
Interresting transmissions effect has been observed, and is
utilised in scanning near-field microscopy.
I will propose a technique with promising applications in
fabrication of holes in metallic film, using organic
components.
This technique will use oxidizing peptides organised in a
lattice on a Si-wafer, using fused SbsB-peptide complexes,
which will we used to cut the holes in the metallic films.
The selection of peptides will be done using commercially
available phage display kits from New England Biolabs,
employing an engineered library of random peptides fused to
the pIII proteine of M13. The phage will be tested for binding
affinity to an Ag substrate, and candidates will be selected
and tested for oxidizing ability, using spectroscopy.
Peptides with appropriate oxidizing properties will then be
fused to the N-terminus of SbsB[3] and self-assembled on an Si-wafer. This self-assembled structure will have a regular lattice spacing.
