L’incorporation de nanoparticules de silice dans les adhésifs révolutionne le collage de matériaux, notamment ceux composés de gels ou de surfaces humides. Ces nanoparticules, en solution aqueuse, forment un réseau fin et poreux qui permet une adhésion forte et rapide entre les surfaces. Grâce à leur taille extrêmement petite (moins de 100 nanomètres), elles interagissent directement avec la structure moléculaire des matériaux collés, créant des liaisons multiples sans réactions chimiques complexes. Cela rend le collage efficace même sur des matériaux mous, glissants ou de nature différente. Parmi les avantages, cette technique procure une adhésion résistante à la déformation, souvent plus solide que les matériaux eux-mêmes, tout en restant perméable aux échanges nécessaires, par exemple dans les tissus biologiques. La colle obtenue est aussi autoréparable: des surfaces décollées peuvent être recollées facilement sans ajouter de nouvelles nanoparticules. De plus, cette méthode fonctionne sans polymères ajoutés ni chauffage, ce qui la rend simple, rapide et adaptée à de nombreuses applications.
