Abstract

The invention discloses a liquid-phase self-assembly method based on evaporation-induced nanoparticles. The method comprises the following steps: (1) preparing silver nanoparticle colloid; (2) addingglycerol with the volume ratio of 0.5% into the silver nanoparticle colloid prepared in the step (1), and uniformly mixing the mixture to form nanoparticle turbid liquid; and (3) dripping the nanoparticle turbid liquid drops obtained in the step (2) onto a hydrophobic glass substrate, and drying the glass substrate and evaporating the solvent water at room temperature to realize nanoparticle self-assembly to form a glycerol-stabilized nanoparticle cluster. The evaporation induced self-assembly technology is adopted, functional group modification does not need to be carried out on the surfacesof the nanoparticles, conjugate connecting molecules such as DNA and a surface modifier do not need to be used, nanoparticle self-assembly can be directly carried out on any substrate, and therefore,the assembled nanoparticles are uniform in gap, high in speed, high in efficiency and low in cost.

Description

technical field [0001] The invention belongs to the technical field of self-assembly of nanomaterials, and in particular relates to a method for self-assembly of nanoparticle liquid phase based on evaporation induction. Background technique [0002] Due to the continuous development of research in the preparation of nanoparticles of different shapes, sizes and materials in recent years, fast and efficient large-area assembly of nanoparticles has great application prospects in biosensing, drug delivery, disease diagnosis, and preparation of new materials. However, unlike the interactions between atoms, the interactions between nanoparticles are very complex, involving van der Waals, electrostatics, solvation / depletion, friction / lubrication, capillary forces, etc. Furthermore, most nanoparticles do not self-assemble into thermodynamically lowest energy states, but form kinetically trapped non-equilibrium structures, thus experimental techniques for assembling nanoparticles int...
