A New Method toward Microengineered Surfaces Based on Reactive Coating
摘要:
By using chemical vapor deposition (CVD) a range of substrates can be coated with a highly reactive polymer containing pentafluorophenol ester groups. A biotin-modified pattern is generated on the substrate by microcontact printing; such a pattern interacts specifically with fluorescein-conjugated streptavidin and thereby the pattern becomes observable with fluorescence microscopy.
Multifunctional reactive polymers created by chemical vapor deposition (CVD) and methods of making such polymeric systems are provided. Such polymers provide multifunctional surfaces which can present two or more different molecules (e.g. biological ligands) in controlled ratios. Polymers may include compositional gradients allowing attached ligands to be presented as continuous gradients across a surface. The polymer compositions are modularly designable and applicable to a wider range of applications, including biomedical devices and diagnostic systems.
