Interfacial adhesion occurs by covalent bonding or noncovalent interactions that are ubiquitous in nature. Adhesive materials are widely desired in many fields including wearable devices, electronic devices, medical surgeries, etc. In recent years, bio-inspired structural adhesive materials and adhesives have been rapidly developed, and some artificial adhesive materials have been put into practical use. However, the restrictions of structural microfabrication and the complexity of synthetic routes limit their large-scale production. In contrast, the nanoparticle solutions provide a simpler and easier alternative to achieve strong adhesion. Here this article makes a highlight on the recent research of "strong anisotropic adhesion of cellulose nanocrystals suspension".

Key words: adhesive, nanocrystal, self-assembly, anisotropic adhesion
