This invention relates to a lift-off process for micro-patterning of plasma-polymerised coatings using micro lithography. The plasma-polymerised surface may be hydrophobic, hydrophilic, cell non-adhesive surface (i.e. a surface which prevents bio-fouling), cell-adhesive surface (surface with high adhesion to cells thereby promoting cell-attachment), conducting, acidic, alkaline, etc. The invention enables patterning of a single or multiple plasma polymerised surfaces on the same substrate. The invention also relates to substrates and devices for use in cell sorting or cell-capture procedures.
本发明涉及一种利用微光刻技术对等离子聚合涂层进行微图案化的升华工艺。等离子聚合表面可以是疏水性表面、亲水性表面、细胞非粘附性表面(即防止生物污染的表面)、细胞粘附性表面(对细胞具有高粘附性从而促进细胞附着的表面)、导电性表面、酸性表面、碱性表面等。本发明可在同一基底上对单个或多个等离子聚合表面进行图案化。本发明还涉及用于细胞分选或细胞捕获程序的基底和装置。
