A method for preparing the outer surface (11) of a planar waveguide (1) for binding target samples along a plurality of predetermined lines (4). The method comprises sequentially applying at least one plurality of linker molecules (2, 5) to the outer surface (11) of a planar waveguide (1) adapted for attachment of a head group (21) of a linker molecule (2) to the outer surface (11) to form an individual layer of linker molecules (2, 5) with individual layers formed one above the other starting from the outer surface (11) of the planar waveguide (1). Each linker molecule (2, 5) comprises a functional group (22, 52) and the head group (21, 51) which is capable of attaching to the outer surface (11) of the planar waveguide (1) or to the functional groups (22) of the preceding layer of linker molecules (2). The functional groups of the uppermost layer are bound to photo-labile protecting groups (3). Exposing those groups (3) of the uppermost layer arranged along a plurality of predetermined lines (4) to light of a predetermined wavelength removes the exposed photo-labile groups (3) from the functional groups (52) to make these functional groups (52) capable of attaching a complementary functional group of a further molecule.
一种制备平面波导(1)外表面(11)的方法,用于沿多条预定线(4)结合目标样品。该方法包括在平面波导(1)的外表面(11)上依次施加至少一个多个连接体分子(2,5),以将连接体分子(2)的头部基团(21)附着在外表面(11)上,从而形成单个连接体分子(2,5)层,单个层从平面波导(1)的外表面(11)开始一个接一个地形成。每个连接剂分子(2,5)都包括一个官能团(22,52)和头部基团(21,51),它们能够附着在平面波导(1)的外表面(11)或前一层连接剂分子(2)的官能团(22)上。最上层的官能团与光敏保护基团(3)结合。将最上层沿多条预定线(4)排列的那些基团(3)暴露在预定波长的光下,可从官能团(52)上去除暴露的光敏基团(3),使这些官能团(52)能够连接另一个分子的互补官能团。
