| As recently reported UV-light patterning of ultrathin self-assembling monolayers (SAMs) of organic molecules for SAMs prepared from amines protected with photolabile groups allows to fabricate a chemical surface pattern or even direct deposition of molecules onto a substrate in one step by means of microcontact printing [Fod91], [Kru02]. In previous work we demonstrated a novel method to fabricate a functional surface pattern for a site-specific deposition of charged nanoparticles and biomolecules, based on optical exposure of a thin, spin-coated aminoterpolymer film, and intrinsically capable of massive parallel processing. The amino groups of the polymer film are protected by UV-labile nitroveratryloxycarbonyl (NVOC) groups [Bra03]. Thus, the film surface can be easily chemically patterned by applying UV light which causes photo-cleavage of the NVOC groups. As a result, the amino function is created at the UV-light exposed area, ready to use for a site-specific immobilization of nanoparticles.

One well known exception is microcontact printing [1], which allows us to fabricate a chemical surface pattern or even direct deposition of molecules onto a substrate in one step in a massively parallel fashion. UV-light patterning of ultra-thin self-assembling monolayers (SAMs) of organic molecules as recently reported for SAMs prepared from amines protected with photolabile groups [2, 3] has the same potential.

Here, we report on a novel method to fabricate a functional surface pattern for a site-specific deposition of charged nanoparticles and biomolecules, based on optical exposure of a thin, spin-coated aminoterpolymer (ATP) film, and intrinsically capable of massive parallel processing. The amino groups of the polymer film are protected by UV-labile nitroveratryloxycarbonyl (NVOC) groups [5]. Thus, the film surface can be easily chemically patterned by applying UV light which causes photo-cleavage of the NVOC groups. As a result, the amino function is created at the UV-light exposed area, ready to use for a site-specific immobilization of nanoparticles. [1] Xia Y and Whitesides G M 1998 Angew.

No source given. Though nearly identical (including references) nothing has been marked as a citation. Passage stems from a paper originated by the research group of which Bsi was a member. Bsi is not named as a co-author or as a participator in the research being described in the paper. Thus she is also not a member of the "we" in "In previous work we demonstrated [...]". There is no entry for [Kru02] in Bsi's list of references. Neither is there one for [Krü02] which would have been the correct reference. |
