Label-Free Measurements of Molecular Transport across Liposome Membranes using Evanescent-Wave Sensing
Artikel i vetenskaplig tidskrift, 2008

Pucker up! A novel approach enabling direct measurements of biomolecular transfer across lipid bilayer membranes, using surface plasmon resonance, is demonstrated. The figure shows the transfer of sucrose (S) through melittin pores formed in surface-attached liposomes. By measuring the shift in refractive index in the volume enclosed by the liposomes, the sucrose transfer can be time-resolved and quantified.
