["Structured liquids in miscible fluids, due to ineffective resistance to withstand particle self-diffusion, differ from that in immiscible liquids because of interfacial interactions. Here, a kind of structured liquid, jammed by thiol-terminated polystyrene-modified gold nanorods (GNRs) within tetrahydrofuran and toluene (TOL), is developed by introducing electrostatic repulsion to counterbalance the self-diffusion of GNRs. First-principle calculations reveal charge transfer between the GNRs and TOL, resulting in the electrostatic repulsion. The structured liquids can be regarded as mimic \"loading vehicles\" to controllably carry and transport matter under electric or magnetic fields, where release rate can be adjusted by changing the concentration of the soluble matter for slow release and using the photothermal effect of the assembled GNRs for fast release. This work has developed a new assembly mechanism to form structured liquids, allowing the construction of a flexible and robust droplet platform with possible applications in microreactors, biomimetic permeable membranes, and functional liquid robots.","Using electrostatic repulsion between nanoparticles and solvent to counterbalance the self-diffusion of the particles, a structured liquid based on miscible fluids without obvious interface is obtained. The structured liquids can be regarded as mimic \"loading vehicles\" to controllably carry, transport and release matter under the applied electric or magnetic fields.image"]
