Sensing scheme for the SPR signal amplification with liposomes. Liposomes are used as label subsequent to the analyte binding to the SPR surface. Although this renders the traditionally label-free SPR method to a label-based detection system, this approach will enable the detection of bound analytes present at low concentration and those providing only minimal changes in RI.
