    Poloxamers are triblock copolymers made of poly(ethylene glycol)-(poly(propylene glycol))-poly(ethylene glycol). They have been shown to enhance gene transfer in the muscle, and co-administration of polymers and DNA appeared to be crucial to obtain this effect. It is questionable then if some interaction occurs between polymers and DNA. Polymer interaction with membranes represents a second crucial point due to the central hydrophobic part of the triblock copolymers. Besides, the question of the polymer spanning or adsorbing to the surface has not been solved by now. We addressed these issues by means of sensitive techniques that allowed working in diluted conditions and gaining in comprehension of gene transfection. By means of simultaneous time-correlated single-photon counting and fluorescence correlation spectroscopy, we have shown that the diffusion time of a single DNA molecule and PicoGreen lifetime was not altered in the presence of the triblock copolymer L64.
