Surface and its manufacture and uses

摘要

A microfabricated device that comprises a liquid transportation system comprising channels and chambers which have a depth ≤ 1000 mu m and are formed in/on a plastic material that comprises a polymerised aliphatic monomer containing unsaturation and being in the form of a copolymer or a homopolymer. The device is characterized in that the aliphatic monomer is a cycloalkene. A kit comprising a) a microfabricated device comprising a surface (i) which is manufactured from a plastic material and (ii) comprises a liquid transportation system of chambers and channels with a depth ≤ 1000 mu m which are covered by a top, and b) a fluorescent substance to be detected in the device and comprising a fluorophor with a distinct maxima in the interval of 400-750 nm. The plastic material has a fluorescence intensity < 50 % of the fluorescent intensity of the fluorescent substance at the wavelength at which the substance fluoresces. The kit is characterized in that the plastic material comprises a homopolymer or a copolymer of an aliphatic monomer comprising a polymerisable carbon-carbon double bond.
