Submicron fabrication of biomolecular patterns using optical methods

Medical Engineering, Nanoelectronics

We have developed a new method for writing of biomolecular patterns on silicon in sub-micron scales using the interference of light. In the first instance DNA patterned surfaces were fabricated. Covalent attachment of DNA oligonucleotides accessible towards hybridisation with a complementary sequence was achieved with very high density (one oligonucleotide per 16 nm²). Further development of the surface attachment chemistry has provided DNA modified patterned substrates for hybridisation with long DNA fragments.
