WebOur approach is based on a drying-driven dynamic assembly process occurring on a liquid surface with the stripe pattern formed by a new type of contact-line instability. Periodic ordering of NCs is realized on microscopic and nanoscopic scales simultaneously without the need of any specialized equipment or the application of external fields. WebNov 1, 2024 · Deblais et al. have demonstrated that using the contact line instability of non-Newtonian fluid, slender liquid micro-filament can be formed in the orthogonal direction to the contact line and this can be used for particle sorting or stretching of DNA molecules [35]. These self-assembled evaporative patterns are highly sensitive to the ...
