We describe fuel-free, near-infrared (NIR)-driven Janus mesoporous silica nanoparticle motors (JMSNMs) with diameters of 50, 80, and 120 nm. The structure the JMSNMs is generated by vacuum sputtering a 10 nm Au layer on one side MSNMs. Upon exposure to an NIR laser, localized photothermal effect half-shells results in formation thermal gradients across JMSNMs; thus, self-thermophoresis can actively drive nanomotors move at ultrafast speed, for instance, up 950 body lengths/s 50 under laser...
We describe an approach to modulating the on-demand motion of catalytic polymer-based microengines via near-infrared (NIR) laser irradiation. The polymer multilayer motor was fabricated by template-assisted layer-by-layer assembly and subsequently deposition platinum nanoparticles inside a thin gold shell outside.

Abstract Photothermal therapy based on gold nanostructures has been widely investigated as a state‐of‐the‐art noninvasive approach. Because single nanoparticles cannot harvest sufficient energy, self‐assemblies of small plasmonic particles into large aggregates are required for enhanced photothermal performance. Self‐assembled nanorods in lipid bilayer‐modified microcapsules shown to localize at tumor sites, generate vapor bubbles under near‐infrared light exposure, and subsequently damage...
Abstract We report a dynamic self‐organization of self‐propelled peanut‐shaped hematite motors from non‐equilibrium driving forces where the propulsion can be triggered by blue light. They result in one‐dimensional, active colloid ribbons with positive phototactic characteristic. The motion is ascribed to diffusion‐osmotic flow chemical gradient photocatalytic decomposition hydrogen peroxide fuel. show that colloids readily form slithering ribbon structures under out‐of‐equilibrium...
The treatment outcomes of oral medications against ulcerative colitis (UC) have long been restricted by low drug accumulation in the mucosa and subsequent unsatisfactory therapeutic efficacy. Here, high-performance pluronic F127 (P127)-modified gold shell (AuS)-polymeric core nanotherapeutics loading with curcumin (CUR) is constructed. Under near-infrared irradiation, resultant P127-AuS@CURs generate transient mild photothermia (TMP; ≈42 °C, 10 min), which facilitates their penetration...
As artificial active colloids, micro-/nanomotors (MNMs) can convert energy from the environment into mechanical motion in different fluids, showing potential applications diverse fields such as targeted drug delivery and photothermal therapy. However, chemical fuels for typical catalytic MNMs, e.g., hydrogen peroxide, are highly toxic to organisms, thus fuel-free MNMs required. Recently, we have developed near-infrared light (NIR) propelled through integrating plasmonic gold nanoshells...
