In this contribution, a mussel inspired polydopamine (PDA) thin film is employed as a protein adhesive layer in surface plasmon enhanced fluorescence (SPF) biosensors, and detection of inflammatory maker Interleukin 6 (IL6) is performed. After a gold surface supporting surface plasmons is coated with PDA, adsorption kinetics of anti-IL6 antibody is taken by surface plasmon resonance spectroscopy. Sandwich immunoassay of IL6 using fluorescence labeled anti-IL6 detection antibody is carried out. The sensing performance of SPF biosensors using PDA coatings, including detection limit of IL6, will be presented.
