Il s'agit d'empêcher les opsonines, ces protéines plasmatiques, de venir se fixer sur les nanovecteurs. Pour ce faire, l'équipe de Patrick Couvreur a fait appel au concept physico-chimique de la «répulsion stérique» qui consiste à greffer à la surface des nanoparticules des chaînes de polymères de polyéthylène glycol (PEG) hydrophiles et flexibles. Grâce à leur mobilité moléculaire, les chaînes de PEG repoussent - par le processus de répulsion stérique - les opsonines et les empêchent de se fixer à la surface des nanovecteurs, qui de ce fait, ne sont plus reconnus par le foie et la rate. 1, record 3, French, - r%C3%A9pulsion%20st%C3%A9rique

Gel Filtration Chromatography. The gel filtration method is a relatively new fractionation procedure in liquid chromatography for the separation of molecules according to the differences in size and shape and can be considered a a kind of "molecular sieve." This method has also been referred to in some publications as exclusion chromatography, restricted diffusion chromatography, restricted diffusion chromatography, gel chromatography and gel permeation chromatography, just to mention a few. 12, record 5, English, - gel%20permeation%20chromatography

When an enzyme is immobilized by using a water-insoluble polymer carrier, the enzyme activity toward substrates of high molecular weight is markedly reduced due to steric hindrance which obstructs the approach of the substrate to the enzyme molecule. However, the activity of immobilized enzyme toward substrates of low molecular weight is similar to that of the native enzyme because the substrate can easily approach the enzyme molecule. 2, record 12, English, - steric%20hindrance
