摘要: Site-specific deposition of nanoparticles and DNA onto micro-patterned aminoterpolymer films is reported. The chemical patterning the film surface accomplished by an easy-to-handle, one-step procedure. Photolabile protection groups are locally removed applying UV light through optical mask. This causes exposure amino to which charged can then associate. End-specific binding at surface-exposed obtained optimum pH conditions. allows a site-specific attachment stretching single molecules patterned polymer surface.
