Abstract |
We developed cyclic olefin copolymer-based immunoassay chips through pre-activated polymer adlayers. For the surface modification of COC substrates we synthesized two types of amphiphilic polymers having three important functions: hydrophobic groups, a PEG component, and an NHS ester group for conjugation of biomolecules. Formation of the polymer adlayers on COC surface was confirmed using a contact angle analyzer. Sandwich immunoassay using anti-rabbit IgG immobilized COC surface showed linear response to rabbit IgG of model analyte over a range from 1 to 1000 ng/mL with detection limit of 1–10 ng/mL. We also fabricated a Lab-On-a Chip type of COC biochip, which could detect a cardiac marker protein, troponin I (TnI), with detection limit of 10 ng/mL. |
