Dandelion flower-like micelles (DFMs) were prepared by self-assembly of polycaprolactone (PCL) functionalized surface cross-linked micelles (SCMs). Upon reductive stimuli, the SCMs can be released from the DFMs by non-Brownian motion at an average speed of 19.09 μm s. Similar to the property of dandelion flowers dispersing their seeds over a long distance, the DFMs demonstrated enhanced multicellular tumor spheroid (MTS) penetration, a useful property in the treatment of many diseases including cancer, infection-of-biofilm diseases and ocular problems.

Due to their affordability and good catalytic activity for oxygen reactions, MOF-derived carbon composites containing metal alloys have piqued interest. However, during synthesis, MOFs have the disadvantage of causing significant carbon evaporation, resulting in a reduction of active sites and durability. This study proposes tailoring the molecular structure of MOFs by optimizing bipyridine and flexible 4-aminodiacetic terephthalic acid ligands, which have numerous coordination modes and framework structures, resulting in fascinating architectures.

We report the reconfigurable assembly of rod-shaped eutectic gallium-indium alloy (EGaIn) liquid metal colloidal motors by mimicking the growth behavior of a dandelion. EGaIn nanorods with a diameter of 210 nm and a length of 850 nm were synthesized via an ultrasound-assisted physical dispersion method. The nanorods possess a core-shell structure with a 30 nm GaOOH shell and zero-valent liquid core.

A novel three-dimensional purple dandelion-like hierarchical AgO@CoO heterojunction with an appropriate redox potential was constructed by chemical precipitation of AgO nanoparticle on flower-like CoO. By feat of this hierarchical structure, the AgO@CoO photocathode showed significantly high photoelectroreduction activities toward -nitrophenol (-NP) and Cr(VI). The high performance of AgO@CoO was mainly attributed to the specific structural characteristics and synergistic effect of each chemical component.
